How do you set up a reactor to get enough water to keep producing steam? by steinio Fri Jan 03, 2020 4:52 pm, Post 75 crafting speed, while the induction furnaces use 3 * 1, so the ratio could be fine tuned a bit. by gGeorg Sat Dec 07, 2019 1:00 am, Post using 3 pumps and a tank, you can feed 28 heat exchangers. This means a single unit of 500C steam has 5.82MW / (60/s) = 0.097 MJ of energy. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. Each offshore pump outputs 1200 units of water per second. But the water only gets heated up from 15C to 500C, so by 485C. Id probably put it on or next to either of the lakes in the middle north or middle south. can you post a screenshot/blueprint? Factorio - The Best Nuclear Power Ratio To generate ten fuel cells, you will need one U-235 cell and nineteen U-238 cells. Create an account to follow your favorite communities and start taking part in conversations. 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. -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. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. Espaol - Latinoamrica (Spanish - Latin America), https://wiki.factorio.com/Tutorial:Nuclear_power#Neighbor_bonus. Press J to jump to the feed. These fuel cells are then burned in a nuclear reactor to create heat. 9.89 gigawatts is a lot. If the only effect the mod has on the game is it changes the total length of one day, without changing the ratio of dusk: day: dawn: night, then the equation can be simplified as. 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. 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. Heat exchangers have different dynamics to actual pipes. A reactor produces 40MW, plus another 40MW for each active neighbouring reactor. Someone already mentioned the normal "build on a lake" strategy. There are mods that can add landfill tiles to existing blueprints if you're up for modding and using a blueprint rather than making your own reactor, and this design is one of my favourites - not objectively "best" perhaps, but has a certain elegance that I deeply appreciate alongside a decent serving of entirely respectable practicality. 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. For each 100% neighbor bonus, the reactor needs 4 more heat exchangers. 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. They represent the number of modules. Then you just connect the reactors to exchangers and exchangers to turbines, also you need about 1 water pump per 10 exchangers (in vanilla). It does not require electricity or fuel to operate. Connect water tank to exchanger for exactly 25k units water. 1 25k tank water disconnected from water input. 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. Each turbine consume 60 water/s so 1200/60=20 turbines. 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. There are also times between day and night called dusk and dawn which complicate the calculations. Reddit and its partners use cookies and similar technologies to provide you with a better experience. I've confirmed that the true value is indeed 5.82, and updated everything accordingly. You may also use this to rectify brownouts/blackouts. and another post in that thread (which calculates the solar panel to megawatt ratio in a different way). Valve Corporation. Don't ask me how that works.) 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. The offshore pump produces water from a lake or ocean. If you want a ratio that's a little easier to remember, those are probably your best bet. 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 astroshak Sat Jan 04, 2020 1:58 am, Post 1 offshore pump: 20 Steam Turbines. One offshore pump can supply 20 boilers and 40 steam engines. In vanilla factorio, without mods which change any of these values, the optimal ratio will be the same. Ratio of heat exchangers to turbines is 1:2, don't bother building lots of pipes for 10% les turbines. 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). Community-run subreddit for the game Factorio made by Wube Software. Includes pipe, pipe to ground, pump, offshore pump, heat pipe. My own personal Factorio super-power - running out of power. See also the applied power math tutorial to answer the question how much coal do I need? And probably how many Offshore Pumps you need for them? 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. This page was last edited on 16 February 2022, at 11:27. An offshore pump produces 1200 units of water per second, which is enough for 116.4 MW. 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. fox hill country club membership cost. 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. chrisgbk 6 yr. ago Technically the HX consumes the water and outputs an equal amount of steam. 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. 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). The current optimal ratio is 1 offshore pump to 20 boilers to 40 steam engines. That's actually just odd. It takes 200J to heat 1 unit of water by 1C. Since steam is produced from water in a 1:1 ratio, this also means that 103 units of water are consumed per second. Here are the total requirements for certain amounts of reactors, with everything rounded up to guarantee maximum energy production. Heat pipes are used to transfer heat from your nuclear reactors to your heat exchangers. Each turbine consume 60 water/s so 1200/60=20 turbines. 120 MW ^Note: Pumps, Steam Turbines and Power are approximate for easier build ratios. This equation could also be used to remember the vanilla optimal ratio given its simplicity. by Honktown Mon Jan 06, 2020 6:52 pm, Post The steam produced is exactly 500C hot, even if the exchanger is hotter. Place some pipes or a tank at the end to see if there is really water coming through. Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. 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. 15 - Factorio Factorio Forums View topic - 0. The ideal ratio is 4 Reactors, 48 Heat Exchangers, 83 Steam Turbines and 5 Water pumps. Are there enough steam generators (boilers, heat exchangers)? Introduction Troubled by pipes having low flow rates? The true maximally efficient layout is a 2 by X rectangle; this gives you access to every reactor. which, given the default time lengths of: day = 12500/60 s; dawn or dusk = 5000/60 s; night = 2500/60 s, and the default: Solar_power = 60 kW; Accumulator_energy = 5 MJ = 5000 kJ, gives the optimal ratio of 0.84 accumulators per solar panel. I concur the ratio is 1:1 cerified through testing. The heat exchanger exchanges heat between a heat connection and water to produce steam. by Bauer Wed Jan 08, 2020 3:04 pm, Post by Honktown Mon Dec 02, 2019 1:56 pm, Post Thanks. As each heat exchanger produces 10 MW, the optimal ratio is 500 steam turbines for every 291 heat exchangers. by azesmbog Fri Nov 29, 2019 4:19 pm, Post Heat exchangers produce ~103 steam with a temperature of 500C every second. One offshore pump can supply 20 boilers and 40 steam engines. Get some landfill to straighten the edge youre gonna use. Press J to jump to the feed. 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. Added high graphics quality option for the steam engine. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. 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. Heat exchangers have a heat capacity of 1 MJ/C. The maximum length of heat pipe you can use depends on the combined distance of your heat exchangers from your reactors. (Low quality because reddit wouldn't let me upload the full png) redditads Promoted. Exchanger outputs to 2 tanks. 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. Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ. This page was last edited on 27 October 2020, at 13:19. So you have 10 + 12 = 22 pipes. One steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2 steam engines: 1.8MW 0.9MW = 2. turbines, exchangers and reactor ratios will vary due to neighbor bonuses. Optimal ratio is 1 offshore pump for every 20 steam turbines; or, 25 offshore pumps for every 291 heat exchangers. All rights reserved. This is taken from Accumulator / Solar Panel Ratio (which calculates this in an impressive mathematical way!) by Honktown Tue Jan 07, 2020 10:30 pm, Post Try this checklist before you completely revamp your power source. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. factorio offshore pump heat exchanger ratio 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. 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. Your other big concern is fluid flow, and the main constraint is the heat flow along heat pipes. Or so. Then have a simple trigger than turns your nuclear plant on and off based on the storage tank steam levels. Originally posted by Alaskan Glitch: The ratio is one water pump will supply a maximum of 20 boilers with water. Each heat exchanger takes a maximum input 10 megawatts of heat and uses it to heat water into steam. Final ratio: 25 offshore pumps : 291 heat exchangers : 500 steam turbines. One Offshore pump can fully supply 12 (11.64) . As shown, making the heat pipes thicker allows supporting heat exchangers that are farther away. However I want to do a different configuration and want to plan out how many of each type of component I need.

Until then it is advisable to not use more than one pump per water network. I found the cheatsheet and wiki which have been quite helpful. The steam produced is exactly 500C hot, even if the exchanger is hotter. Tutorial:Main bus. Is the factory producing enough fuel (coal, solid fuel, uranium fuel cells)? by Honktown Fri Jan 03, 2020 8:34 pm, Post Heat pipes (also in reactors and heat exchangers) glow with high temperatures. In theory, there is no difference between theory and practice. A reactor without neighbor bonus needs 4 heat exchangers so that all its heat gets consumed. (100% neighbor bonus per adjacent reactor). Additional comment actions. Click on an empty cell to place a nuclear power plant. Create an account to follow your favorite communities and start taking part in conversations. #footer_privacy_policy | #footer . Each boiler is capable of producing enough 165C steam for two steam generators. you should have a 2 by X rectangle with one reactor dangling off the end. Change fluidbox height and base level of boiler, steam engine and pump to improve fluid flow. This layout produces 40 MW output ( 1 SRE ). In practice, there is. 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. 40 MW of power output is consumed by 4 Heat Exchangers (10MW per Heat Exchanger ). I have been reading all about Nuclear power so I can convert my factory. 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. The Factorio devs plan some refactoring for the upcoming version 0.17. Build the reactor over a lake, with careful placement of landfill you can have pumps directly feeding each end of the heat exchanger line. by mrvn Fri Nov 29, 2019 4:41 pm, Post 20. All trademarks are property of their respective owners in the US and other countries. 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. If not, ensure all. When producing power, the steam engine will display a working animation: https://wiki.factorio.com/index.php?title=Steam_engine&oldid=188232. by disentius Tue Jan 07, 2020 9:36 pm, Post Community-run subreddit for the game Factorio made by Wube Software. 4 Heat Exchangers boil 412.36 Water to Steam per second (103.09 per Heat Exchanger ). 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. 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. Each heat exchanger converts 103 water to 103 steam, feeding 1.72 turbines. The throughput of a fluid pipe depends on the length of said pipe, but you can put in pumps to pressurize the pipe and increase the throughput. This produces the 1:20:40 ratio. Steam engines have two ports, allowing excess steam to flow through. Heat exchangers will not produce steam until they reach 500C. Privacy Policy. The most heat exchangers I've been able to fit on a single length of heat pipe is 30 heat exchangers on 44 heat pipes; any more than that incurs significant heat loss. Heat exchangers are pipes too. It took me 4 days to figure out the ratios related to nuclear power, so I figured I'd share. 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. A theory without practice is dead, practice without a theory is blind, this quote is attributed to commander Alexander Suvorov. It produces 1200 units of water per second. This can be extended as far as you want; every additional 2 reactors will provide an additional 320 megawatts of heat output. Factorio version: 0.17 - 1.1 Downloaded by: 6.01K users Summary Adds scaled up versions in different sizes for various pipes and pumps. Espaol - Latinoamrica (Spanish - Latin America). by disentius Fri Nov 29, 2019 9:15 pm, Post Reddit and its partners use cookies and similar technologies to provide you with a better experience. 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. Water: is a liquid which can be infinitely extracted from water tiles using an offshore pump; Steam: is a gas you can create by heating water in a boiler or heat exchanger; Other Factorio Guides: Boiler to Steam Ratio; Solar Panel Ratio; Console Commands & Cheats Don't know how to use a machine? fox hill country club membership cost. 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. The flow between pipes and heat exchangers is also different to pump to heat exchangers. Also, the optimal ratio is: 1 offshore pump / 14 boilers / 10 steam engines is that 10 for each boiler? This means that you need 1.428 MW of production (of solar panels) and 100MJ of storage to provide 1 MW of power over one day-night cycle. One exchanger 3 storage tanks plus inf heat. 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. For more information, please see our Each uranium fuel cell will power a nuclear reactor for 200 seconds. Is there any info about how much water per second Heat Exchangers use? Neighbor bonuses make nuclear very efficient: 1 reactor = 40MW = 4 exchangers = 7 turbines However you did warn me: Save often and reload if necessary during landfilling. 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). 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. Calculator for the Nuclear Reactor. You can sideload water for a 1.1 GW plant. Finally, after 20 hours of work, I present the flowchart for Pyanodon Space Science! All rights reserved. A heat exchanger consumes 10 MW. It's recommended to build them near or on bodies of water, as that lets you place offshore pumps where ever you want. All trademarks are property of their respective owners in the US and other countries. This page was last edited on 13 September 2019, at 23:48. One steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2 steam engines: 1.8MW 0.9MW = 2. 412.36 Water requires 1 ( 0.34) Offshore Pumps (1200 per Offshore Pump ). The optimal ratio of accumulators per solar panel relies on many values in the game. SmartAlec105 having more than 2 steam engines per boiler could do that. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. makes troubleshooting easier. Nuclear power plants mostly need a lot of water. Don't ask me how that works.). There are multiple methods to produce electricity: Each steam engine needs 0.5 boilers when running at full capacity. So we know that one offshore pump can supply 20 boilers but is that the same for heat exchangers? One boiler consumes 1. Neighbor bonuses make nuclear very efficient: 1 reactor = 40MW = 4 exchangers = 7 turbines, 2 reactor = 160MW = 16 exchangers = 28 turbines, 4 reactor = 480MW = 48 exchangers = 83 turbines.
