You can also have some steam tanks with additional turbines for power spikes (laser turrets etc) as reactors always work with 100% power tanks will store steam when you're not using it all), Factorio Cheat Sheet - That's all the information you need. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. Place some pipes or a tank at the end to see if there is really water coming through. So you have 10 + 12 = 22 pipes. Use the lake west of your copper mine. 6, crafting time is 15s, producing 0. Yogi Berra. Mark IIIs are unable to complete a full cycle without going into meltdown and thus need to be shutdown mid-cycle in order to deal with the high amount of excess heat. Ratio of reactors to whatever is 2x2 480MW reactor to 10MW heat exchanger, ratio of reactors to miners is 1:4 iirc, so double that miners, You will need 1x2 chunks space near water, so anywhere, maybe next to Oil Field's Uranium patch. If not, ensure all. This page was last edited on 27 October 2020, at 13:19. A powered nuclear reactor outputs 40 megawatts of heat, plus an additional 40 megawatts for each powered nuclear reactor directly adjacent to it. A perfect square of reactors has the highest theoretical efficiency, but at 3x3 and above you'll have reactors surrounded on all 4 sides and have no way to load the uranium fuel cells. Additional comment actions. EDIT NOTE: The original version of the post used the wrong output for steam turbines (5.8 MW instead of 5.82). One offshore pump can supply 20 boilers and 40 steam engines. The number of boilers can be derived from the number of steam engines: 40 2 = 20. Each uranium fuel cell will power a nuclear reactor for 200 seconds. The true maximally efficient layout is a 2 by X rectangle; this gives you access to every reactor. Each steam turbine take a maximum input of 60 units of 500 C steam per second and outputs 5.82 megawatts of electricity; the 5.8 megawatts listed on the tooltip is rounded. That's actually just odd. Exchanger outputs to 2 tanks. Cookie Notice Reddit and its partners use cookies and similar technologies to provide you with a better experience. The main thing to remember is that Factorio generally follows the laws of thermodynamics; if your nuclear reactor produces 40 megawatts of heat, you can get a maximum of 40 megawatts of electricity out the other side. It does not require electricity or fuel to operate. Are there enough steam generators (boilers, heat exchangers)? Using steam engines for power does not produce pollution, however using boilers to heat up the water does. Is there any info about how much water per second Heat Exchangers use? Press question mark to learn the rest of the keyboard shortcuts. r/factorio . Valve Corporation. A "close enough" ratio is 20:24:1 accumulators to solar panels to megawatts required (for example, a factory requiring 10 MW can be approximately entirely powered, day and night, by 200 accumulators and 240 solar panels - this approximation differs from optimal only in that it calls for 20 extra solar panels, which is negligible but remember that the difference between the "close enough" ratio and the optimal ratio increases as you add more solar panels). This produces the 1:20:40 ratio. Pump Ratio ^ 1. SmartAlec105 having more than 2 steam engines per boiler could do that. #footer_privacy_policy | #footer . Stuck in a mission? By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. It takes 200J to heat 1 unit of water by 1C. Community-run subreddit for the game Factorio made by Wube Software. Then you just connect the reactors to exchangers and exchangers to turbines, also you need about 1 water pump per 10 exchangers (in vanilla). The steam production rate can also be calculated using the energy consumption: 1 Heat exchanger consumes 10MW, so it's putting 10,000,000 joule of energy into heating water/steam per second. Reddit and its partners use cookies and similar technologies to provide you with a better experience. chrisgbk 6 yr. ago Technically the HX consumes the water and outputs an equal amount of steam. Each heat exchanger takes a maximum input 10 megawatts of heat and uses it to heat water into steam. Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. Community-run subreddit for the game Factorio made by Wube Software. (Low quality because reddit wouldn't let me upload the full png) redditads Promoted. using 3 pumps and a tank, you can feed 28 heat exchangers. The current optimal ratio is 1 offshore pump to 20 boilers to 40 steam engines. The lake under the oil field looks like a nice place, letting you place offshore pumps near the center, with the turbines extending to land. A compendium of the most common Factorio game facts, such as build ratios, tips/tricks, . What I can't find is how much water a heat exchanger *consumes* to produce the 103ish steam per second. Give exchanger max heat you can then let the exchanger turn 25k water into steam. A reactor without neighbor bonus needs 4 heat exchangers so that all its heat gets consumed. Don't know how to use a machine? The optimal ratio is 0.84 (21:25) accumulators per solar panel, and 23.8 solar panels per megawatt required by your factory (this ratio accounts for solar panels needed to charge the accumulators). by gGeorg Sat Dec 07, 2019 1:00 am, Post In general, nuclear power is produced by the following production chain: Uranium ore is mined and processed to uranium-235 and uranium-238, then uranium fuel cells are created from the two. See also the applied power math tutorial to answer the question how much coal do I need? The Factorio devs plan some refactoring for the upcoming version 0.17. I get that offshore pumps produce 1200 units of water per second. Geplaatst op 3 juli 2022 door . I found the cheatsheet and wiki which have been quite helpful. Remember that water in pipes still obeys Factorio physics; if you pipe your water a long distance, you may not get the full 1200/s. factorio offshore pump heat exchanger ratio The heat exchanger exchanges heat between a heat connection and water to produce steam . This layout produces 40 MW output ( 1 SRE ). Introduction Troubled by pipes having low flow rates? Heat exchangers produce ~103 steam with a temperature of 500C every second. The maximum length of heat pipe you can use depends on the combined distance of your heat exchangers from your reactors. Heat pipes (also in reactors and heat exchangers) glow with high temperatures. Click on an empty cell to place a nuclear power plant. by steinio Fri Jan 03, 2020 4:52 pm, Post Not sure where you got those numbers from, but in 0.15, small pumps and offshore pumps pump at exactly the same rate: 1200 fluid/s. All rights reserved. Heat exchangers will not produce steam until they reach 500C. Hovering the mouse over a steam engine will display their current power production (Performance) and their possible power production (Available Performance), in a display on the right. Id probably put it on or next to either of the lakes in the middle north or middle south. This link for calculations. So far I have built/replaced 3 reactor sectors to be on the lake rather than beside the lake, and I am pretty happy with the results (600 fewer pipes, 800 fewer underground pipes). Heat exchangers have different dynamics to actual pipes. They produce electricity by consuming steam, using water pumped from an offshore pump that was heated to 165C steam with boilers or to 500C steam with heat exchangers. One steam engine consumes 30 steam per second, and one offshore pump produces 1200 water per second, so each offshore pump produces enough water to supply 40 steam engines: 1200 unit/s 30 units/s = 40. by Honktown Tue Jan 07, 2020 10:30 pm, Post Includes pipe, pipe to ground, pump, offshore pump, heat pipe. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. However you did warn me: Save often and reload if necessary during landfilling. This means a single unit of 500C steam has 5.82MW / (60/s) = 0.097 MJ of energy. Steam engines will automatically adjust their power production and steam usage based on the current demands of the electricity network. Espaol - Latinoamrica (Spanish - Latin America). Does the game consider 1 water = 1 steam (just a different temperature?) by Amarula Mon Dec 02, 2019 3:51 pm, Post The above ratio can be calculated from information available in-game: One boiler consumes 1.8MW of fuel and produces energy stored in steam at 100% efficiency. Also, before you set it up, make sure you nuke any landfill land to get a little pollution absorption to help manage your Fun fumes cloud. However I want to do a different configuration and want to plan out how many of each type of component I need. Build the reactor over a lake, with careful placement of landfill you can have pumps directly feeding each end of the heat exchanger line. Additional comment actions. Here are the total requirements for certain amounts of reactors, with everything rounded up to guarantee maximum energy production. 1 25k tank water disconnected from water input. The technical implementation details of Factorio's pipe system still have some room for improvement. On a lake, very carefully - they consume a monstrous amount of water, and having the multiple required offshore pumps integrated directly into the design is often worth the hassle of wrangling landfill. Post You can sideload water for a 1.1 GW plant. by Amarula Fri Jan 03, 2020 4:45 pm, Post So a heat exchanger generated 103 steam per second is 103 water per second I need from my offshore pump. Someone already mentioned the normal "build on a lake" strategy. factorio offshore pump heat exchanger ratio and another post in that thread (which calculates the solar panel to megawatt ratio in a different way). Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. The heat can be used to convert water to steam using a heat exchanger and the steam can be consumed by steam turbines to produce power. 40 MW of power output is consumed by 4 Heat Exchangers (10MW per Heat Exchanger ). Your other big concern is fluid flow, and the main constraint is the heat flow along heat pipes. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. Tutorial:Main bus. . All trademarks are property of their respective owners in the US and other countries. Steam that has a higher temperature than the maximum temperature of the steam engine (165C) is consumed at the normal rate (30 units/s), and does not yield more electricity. Calculator for the Nuclear Reactor. The more heat exchangers you want to put on a single length of heat pipe, the shorter that heat pipe has to be to ensure minimal heat loss; e.g. Heat exchangers produce ~103 steam with a temperature of 500C every second. by Bauer Wed Jan 08, 2020 3:04 pm, Post One boiler consumes 1. Now you have 0 waste of fuel. Designed for supporting scaled up machines from "Schall Machine Scaling" mod. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. Look at the windows in the pipes, hover over the pipes! Neighbor bonuses make nuclear very efficient: 1 reactor = 40MW = 4 exchangers = 7 turbines 120 MW ^Note: Pumps, Steam Turbines and Power are approximate for easier build ratios. (100% neighbor bonus per adjacent reactor). fox hill country club membership cost. Each boiler is capable of producing enough 165C steam for two steam generators. Heat pipes are used to transfer heat from your nuclear reactors to your heat exchangers. When producing power, the steam engine will display a working animation: https://wiki.factorio.com/index.php?title=Steam_engine&oldid=188232. And probably how many Offshore Pumps you need for them? There is a handy table on the factorio wiki listing the throughput for different lengths of pipe between pumps. It must be placed on a shoreline of a body of water on the map, and connected to a pipe or other object that accepts liquids. Do your pipes have water? 20. You can check the usage on the turbines as well as the production stat on the offshore pump. by leitk Mon Dec 02, 2019 4:29 am, Post The water calculation has me stumped. The glow of the heat pipes indicates temperature, with left ends being at the upper limit of 1000C. Ratio of heat exchangers to turbines is 1:2, don't bother building lots of pipes for 10% les turbines. So a 2x2 block produces 480MW (4*3*40). Don't ask me how that works.). Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. I wasn't sure if Heat exchanger converts 1 water into 1 steam and there is nothing written in its tooltip. 412.36 Water requires 1 ( 0.34) Offshore Pumps (1200 per Offshore Pump ). Fresh water is at 15C while the steam produced by heat exchangers and consumed by steam turbines is at 500C, a difference of 485C, so you need 1 unit of water for each 97kJ, which is roughly 10.3 units per MJ. This ratio is. This means the energy that was put into the steam to heat it to a higher temperature is wasted. The lake under the oil field looks like a nice place, letting you place offshore pumps near the center, with the turbines extending to land. Perfectly optimal solar network (Factorio forums), 1 solar panel produces 42KW after factoring in the night (Factorio forums), https://wiki.factorio.com/index.php?title=Power_production&oldid=182968. by mrvn Fri Nov 29, 2019 4:41 pm, Post Reddit and its partners use cookies and similar technologies to provide you with a better experience. One pump can supply up to 20 boilers. Valve Corporation. Also iirc tanks limit liquid throuput when it flows through them, so try connecting them on the side and not in-line if you have to at all. If you run an odd number of reactors, you should have a 2 by X rectangle with one reactor dangling off the end. If you inexplicably want to go back to a 4 year old build of Factorio then you will need to build 14 boilers in a row (they each used to heat the water up by a little bit), followed by 10 steam engines. Factorio - The Best Nuclear Power Ratio To generate ten fuel cells, you will need one U-235 cell and nineteen U-238 cells. Heat exchangers produce 103 steam/second.This can be calculated by relying on steam turbine data: A steam turbine consumes 60 steam/second and produces 5.82MW (assuming 500C steam). by astroshak Sat Jan 04, 2020 1:58 am, Post Added high graphics quality option for the steam engine. The current optimal ratio is 1 offshore pump to 20 boilers to 40 steam engines. In theory, there is no difference between theory and practice. Privacy Policy. The steam produced is exactly 500C hot, even if the exchanger is hotter. 9.89 gigawatts is a lot. Espaol - Latinoamrica (Spanish - Latin America), https://wiki.factorio.com/Tutorial:Nuclear_power#Neighbor_bonus. The main thing to remember is that Factorio generally follows the laws of thermodynamics; if your nuclear reactor produces 40 megawatts of heat, you can get a maximum of 40 megawatts of electricity out the other side. They produce electricity by consuming steam, using water pumped from an offshore pump that was heated to 165C steam with boilers or to 500C steam with heat exchangers. It's recommended to build them near or on bodies of water, as that lets you place offshore pumps where ever you want. This page was last edited on 16 February 2022, at 11:27. by disentius Fri Nov 29, 2019 9:15 pm, Post By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Change fluidbox height and base level of boiler, steam engine and pump to improve fluid flow. Nuclear reactors have a maximum temperature of 1000 C. Unlike boilers, nuclear reactors will not slow or stop their fuel consumption if their output isn't being used; they'll constantly use up fuel cells at the normal rate of 1 fuel cell / 200 seconds. This page was last edited on 13 September 2019, at 23:48. Heat exchangers have a heat capacity of 1 MJ/C. Is steam able to reach all steam engines? The ideal ratio is 4 Reactors, 48 Heat Exchangers, 83 Steam Turbines and 5 Water pumps. This equation could also be used to remember the vanilla optimal ratio given its simplicity. One steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2 steam engines: 1.8MW 0.9MW = 2. If the player uses mods which change the power generation of solar panels, or the energy storage of accumulators, but not the length of days, a simplified version of this equation can be used. I concur the ratio is 1:1 cerified through testing. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. 75 crafting speed, while the induction furnaces use 3 * 1, so the ratio could be fine tuned a bit. -adding a second off-shore pump to start off with twice as much water (in theory); -putting in more pumps, say one pump for every underground pipe; -putting in a complete second line from off-shore pump to heat exchangers with a pump every 5 underground pipes. The steam production rate can also be calculated using the energy consumption: 1 Heat exchanger consumes 10MW, so it's putting 10,000,000 joule of energy into heating water/steam per second. If your heat pipe is too long, your reactors will max out at 1000 C before your heat exchangers can reach a steady state of 500 C, and and you'll start to waste heat. What does clicking on an item's icon in the "Factory" tab do? Fresh water is at 15C while the steam produced by heat exchangers and consumed by steam turbines is at 500C, a difference of 485C, so you need 1 unit of water for each 97kJ, which is roughly 10.3 units per MJ. They only work when they're above 500 C, and have a maximum temperature of 1000 C. Temperatures above 500 don't increase efficiency; the exchanger will just store the heat, which it can then use later. 1 offshore pump: 20 Steam Turbines. by disentius Tue Jan 07, 2020 9:36 pm, Post HolyGarbage . This allows steam engines to be chained together. The above ratio can be calculated from information available in-game: One boiler consumes 1.8MW of fuel and produces energy stored in steam at 100% efficiency. This is taken from Accumulator / Solar Panel Ratio (which calculates this in an impressive mathematical way!) Factorio version: 1.1 Downloaded by: 1.88K users WHAT IS OFFSHORE P.U.M.P.S.? I think it is easiest to just have an abundance of storage tanks for the steam. How do you set up a reactor to get enough water to keep producing steam? Optimal ratio is 1 offshore pump for every 20 steam turbines; or, 25 offshore pumps for every 291 heat exchangers. To heat up 1 unit of water 1 degree, 200 joules are needed, so the heat exchanger is heating up water by 50,000C in total. by Honktown Fri Jan 03, 2020 8:34 pm, Post As far as I can tell, the absolute smallest perfect-ratio setup possible is: which would require an input of 1.46 uranium fuel cells per second and output a cool 46.56 gigawatts of electricity. Don't ask me how that works.) Any experiences/suggestions/comments are welcome. The steam produced is exactly 500C hot, even if the exchanger is hotter. One offshore pump can supply 20 boilers and 40 steam engines. I've confirmed that the true value is indeed 5.82, and updated everything accordingly. So the 50,000C are enough to heat up 103 units of steam per second, since 50,000 / 485 = 103.09. by mrvn Wed Jan 08, 2020 3:42 pm, Post Thus, they can buffer 500 MJ of heat energy across their working range of 500C to 1000C, and require 485 MJ of energy to warm up from 15C to 500C when initially placed. There are also times between day and night called dusk and dawn which complicate the calculations. But the water only gets heated up from 15C to 500C, so by 485C. 1 electric pump can keep up with rate of roughly 10 water pumps if i recall, so at least you don't need to have pump and waterpump flows in parallel. A heat exchanger consumes 10 MW. At full 10 MW load this is 103.096 water per second. Geplaatst op 3 juli 2022 door . Each offshore pump outputs 1200 units of water per second. All rights reserved. Steam engines are the most basic electricity generator, available to the player at the start of the game. Yes, there is also a maximum throughput for water that depends on the distance the . by mrvn Wed Jan 08, 2020 3:45 pm, Powered by phpBB Forum Software phpBB Limited. and our Steam that has a higher temperature than the maximum temperature of the steam engine (165C) is consumed at the normal rate (30 units/s), and does not yield more electricity. Do the numbers in the "beacons" column represent the number of modules or the number of beacons? For each 100% neighbor bonus, the reactor needs 4 more heat exchangers. Each heat exchanger converts 103 water to 103 steam, feeding 1.72 turbines. by Amarula Fri Nov 29, 2019 3:09 pm, Post There are multiple methods to produce electricity: Each steam engine needs 0.5 boilers when running at full capacity. These include the power generation of a solar panel, the energy storage of an accumulator, the length of a day, and the length of a night. The heat exchanger exchanges heat between a heat connection and water to produce steam. P UMPING U NITS M EETING P HYSICS S TANDARDS This mod started off as a project to sustain my most eco-unfriendly excessive water needs by implementing some Higher Tier Offshore Pumps. The optimal ratio of accumulators per solar panel relies on many values in the game. Nuclear power plants mostly need a lot of water. u/asdjfsjhfkdjs calculated the convergents of 500:291, and found that 7 : 4 and 55 : 32 are both fairly accurate approximations.
