Try this checklist before you completely revamp your power source. u/asdjfsjhfkdjs calculated the convergents of 500:291, and found that 7 : 4 and 55 : 32 are both fairly accurate approximations. But the water only gets heated up from 15C to 500C, so by 485C. 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. 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. This can be extended as far as you want; every additional 2 reactors will provide an additional 320 megawatts of heat output. An offshore pump produces 1200 units of water per second, which is enough for 116.4 MW. Factorio Oil Refinery 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. Factorio Reactor DesignsThis is a good measure to combat "spaghetti -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. This produces the 1:20:40 ratio. Change fluidbox height and base level of boiler, steam engine and pump to improve fluid flow. Connect water tank to exchanger for exactly 25k units water. Tutorial:Main bus. makes troubleshooting easier. Each heat exchanger takes a maximum input 10 megawatts of heat and uses it to heat water into steam. Steam engines' power output really low :: Factorio General Discussions See also the applied power math tutorial to answer the question how much coal do I need? Electricity has to be produced before it can be transferred to consumers over the electric system. 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. A heat exchanger consumes 10 MW. 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. Valve Corporation. Exchanger outputs to 2 tanks. However I want to do a different configuration and want to plan out how many of each type of component I need. 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. So I've run into an issue with water for my Turbines. 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). It takes 200J to heat 1 unit of water by 1C. 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. 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. There is a handy table on the factorio wiki listing the throughput for different lengths of pipe between pumps. Heat exchangers will not produce steam until they reach 500C. In a vanilla game that's. what, 1k science a minute? Offshore pump - Factorio Wiki 75 crafting speed, while the induction furnaces use 3 * 1, so the ratio could be fine tuned a bit. Geplaatst op 3 juli 2022 door . This equation could also be used to remember the vanilla optimal ratio given its simplicity. The heat exchanger exchanges heat between a heat connection and water to produce steam. by gGeorg Sat Dec 07, 2019 1:00 am, Post Build the reactor over a lake, with careful placement of landfill you can have pumps directly feeding each end of the heat exchanger line. One steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2 steam engines: 1.8MW 0.9MW = 2. by Amarula Fri Jan 03, 2020 4:45 pm, Post Offshore Pumps ratios and questions :: Factorio General Discussions Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. 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. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. It does not require electricity or fuel to operate. It takes 200J to heat 1 unit of water by 1C. (100% neighbor bonus per adjacent reactor). Factorio version: 1.1 Downloaded by: 1.88K users WHAT IS OFFSHORE P.U.M.P.S.? Introduction Troubled by pipes having low flow rates? 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. Offshore pump/heat exchanger ratio? : r/factorio - reddit fox hill country club membership cost. 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. Thanks. 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. Is steam able to reach all steam engines? Since heat exchangers consume 103.1 water each, a few dozen seems reasonable if . Don't ask me how that works.) This means the energy that was put into the steam to heat it to a higher temperature is wasted. Steam engines are the most basic electricity generator, available to the player at the start of the game. For each 100% neighbor bonus, the reactor needs 4 more heat exchangers. That's actually just odd. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. If you want a ratio that's a little easier to remember, those are probably your best bet. chrisgbk 6 yr. ago Technically the HX consumes the water and outputs an equal amount of steam. If not, ensure all. Your other big concern is fluid flow, and the main constraint is the heat flow along heat pipes. https://wiki.factorio.com/index.php?title=Heat_exchanger&oldid=175988. 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. At full 10 MW load this is 103.096 water per second. by Bauer Wed Jan 08, 2020 3:04 pm, Post Each offshore pump outputs 1200 units of water per second. I wasn't sure if Heat exchanger converts 1 water into 1 steam and there is nothing written in its tooltip. One pump can supply up to 20 boilers. However you did warn me: Save often and reload if necessary during landfilling. It took me 4 days to figure out the ratios related to nuclear power, so I figured I'd share. EDIT NOTE: The original version of the post used the wrong output for steam turbines (5.8 MW instead of 5.82). Heat pipes are used to transfer heat from your nuclear reactors to your heat exchangers. Since steam is produced from water in a 1:1 ratio, this also means that 103 units of water are consumed per second. 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 means a single unit of 500C steam has 5.82MW / (60/s) = 0.097 MJ of energy. The glow of the heat pipes indicates temperature, with left ends being at the upper limit of 1000C. A powered nuclear reactor outputs 40 megawatts of heat, plus an additional 40 megawatts for each powered nuclear reactor directly adjacent to it. by leitk Mon Dec 02, 2019 4:29 am, Post Id probably put it on or next to either of the lakes in the middle north or middle south. and our In vanilla factorio, without mods which change any of these values, the optimal ratio will be the same. Each heat exchanger converts 103 water to 103 steam, feeding 1.72 turbines. Steam engine - Factorio Wiki Get some landfill to straighten the edge youre gonna use. by astroshak Wed Jan 08, 2020 11:15 am, Post I get that offshore pumps produce 1200 units of water per second. 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. Don't ask me how that works.). 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. 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. It's recommended to build them near or on bodies of water, as that lets you place offshore pumps where ever you want. 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. Water consumption for heat exchangers math : r/factorio - reddit factorio offshore pump heat exchanger ratio 412.36 Water requires 1 ( 0.34) Offshore Pumps (1200 per Offshore Pump ). One offshore pump can supply 20 boilers and 40 steam engines. Are there enough steam generators (boilers, heat exchangers)? It produces 1200 units of water per second. by Amarula Mon Dec 02, 2019 3:51 pm, Post where game_day is the number of seconds in the game day which is 25000/60 s by default. 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.

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. Additional comment actions. 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. Refer to Francis John play through video on YouTube on nuclear power. by steinio Fri Jan 03, 2020 4:52 pm, Post (Except that you can potentially turn 8 gigajoules of uranium fuel cell into 40 gigajoules of heat. 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. Until then it is advisable to not use more than one pump per water network. There's no clear ratio as you need to account for heat bonus from other reactors but it's quite easy to calculate yourself, if you fuel the reactors it will show you produced heat in MW (with bonus) you just sum up all reactors and divide by heat exchanger power (all power/power per 1 hear exchanger) to get the number, then you do the same for turbines (all power/power per 1 turbine). One offshore pump can supply 20 boilers and 40 steam engines. Alt-F4 #57 - Nuclear Energy and You - Alternative Friday Factorio Fan Facts This page was last edited on 16 February 2022, at 11:27. Originally posted by Alaskan Glitch: The ratio is one water pump will supply a maximum of 20 boilers with water. 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. 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. Click on an empty cell to place a nuclear power plant. What I can't find is how much water a heat exchanger *consumes* to produce the 103ish steam per second. factorio - Water with low pressure - Arqade 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. Stuck in a mission? The heat exchanger exchanges heat between a heat connection and water to produce steam . 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. So the 50,000C are enough to heat up 103 units of steam per second, since 50,000 / 485 = 103.09.

Calculator for the Nuclear Reactor. by Honktown Mon Dec 02, 2019 1:56 pm, Post There are multiple methods to produce electricity: Each steam engine needs 0.5 boilers when running at full capacity. A reactor produces 40MW, plus another 40MW for each active neighbouring reactor. Give exchanger max heat you can then let the exchanger turn 25k water into steam. This ratio is. You can sideload water for a 1.1 GW plant. 40 MW of power output is consumed by 4 Heat Exchangers (10MW per Heat Exchanger ). Neighbor bonuses make nuclear very efficient: 1 reactor = 40MW = 4 exchangers = 7 turbines Community-run subreddit for the game Factorio made by Wube Software. As shown, making the heat pipes thicker allows supporting heat exchangers that are farther away. Nuclear power plants mostly need a lot of water. A compendium of the most common Factorio game facts, such as build ratios, tips/tricks, . A theory without practice is dead, practice without a theory is blind, this quote is attributed to commander Alexander Suvorov. Factorio Boiler To Steam Engine Ratio5/90 and add it to the pollution Each turbine consume 60 water/s so 1200/60=20 turbines. Doubled the heat capacity of water from 0.1kJ per degree per liter to 0.2kJ.
