I've confirmed that the true value is indeed 5.82, and updated everything accordingly. As shown, making the heat pipes thicker allows supporting heat exchangers that are farther away. 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. As each heat exchanger produces 10 MW, the optimal ratio is 500 steam turbines for every 291 heat exchangers. 12. 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. Espaol - Latinoamrica (Spanish - Latin America). by azesmbog Fri Nov 29, 2019 4:19 pm, Post 1 25k tank water disconnected from water input. Heat exchangers produce ~103 steam with a temperature of 500C every second. 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. One steam engine consumes 900kW of energy stored in steam, so each boiler can supply 2 steam engines: 1.8MW 0.9MW = 2. 15 - Factorio Factorio Forums View topic - 0. What does clicking on an item's icon in the "Factory" tab do? A powered nuclear reactor outputs 40 megawatts of heat, plus an additional 40 megawatts for each powered nuclear reactor directly adjacent to it. Since heat exchangers consume 103.1 water each, a few dozen seems reasonable if . 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. However I want to do a different configuration and want to plan out how many of each type of component I need. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. 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. 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. 9.89 gigawatts is a lot. 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. Look at the windows in the pipes, hover over the pipes! 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. The glow of the heat pipes indicates temperature, with left ends being at the upper limit of 1000C. The number of boilers can be derived from the number of steam engines: 40 2 = 20. You can check the usage on the turbines as well as the production stat on the offshore pump. Heat exchanger heats 15C water to 500C steam; It takes 0.2 kJ of burner energy to raise 1 water 1C; Steam is consumed by steam turbines at a rate of 60 units per second; (500C - 15C) 0.2 kJ 60 units = 5820 kW, or 5.82 MW. The heat exchanger exchanges heat between a heat connection and water to produce steam. by mrvn Wed Jan 08, 2020 3:45 pm, Powered by phpBB Forum Software phpBB Limited. One pump can supply up to 20 boilers. chrisgbk 6 yr. ago Technically the HX consumes the water and outputs an equal amount of steam. Press J to jump to the feed. 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. Each turbine consume 60 water/s so 1200/60=20 turbines. 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. A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. by astroshak Sat Jan 04, 2020 1:58 am, Post If you overbuild reactors, you can end up wasting a lot of fuel cells without realizing it. 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. And probably how many Offshore Pumps you need for them? Press question mark to learn the rest of the keyboard shortcuts. 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. 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.

Geplaatst op 3 juli 2022 door . 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. See also the applied power math tutorial to answer the question how much coal do I need? 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 produces 1200 units of water per second. 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 Bauer Wed Jan 08, 2020 3:04 pm, Post Calculator for the Nuclear Reactor. One boiler consumes 1. So you have 10 + 12 = 22 pipes. So I've run into an issue with water for my Turbines. Try this checklist before you completely revamp your power source. Don't ask me how that works.) If not, ensure all. Privacy Policy. One exchanger 3 storage tanks plus inf heat. Neighbor bonuses make nuclear very efficient: 1 reactor = 40MW = 4 exchangers = 7 turbines Or so. They represent the number of modules. 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. Post 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. 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. Any experiences/suggestions/comments are welcome. by eradicator Fri Nov 29, 2019 4:43 pm, Post Thanks. 412.36 Water requires 1 ( 0.34) Offshore Pumps (1200 per Offshore Pump ).

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 Fri Jan 03, 2020 8:34 pm, Post 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. Valve Corporation. A steam turbine consumes 60 units of steam per second, which is 5.82 MW. This means the energy that was put into the steam to heat it to a higher temperature is wasted. All rights reserved. (100% neighbor bonus per adjacent reactor). So we know that one offshore pump can supply 20 boilers but is that the same for heat exchangers? The water calculation has me stumped. One offshore pump can supply 20 boilers and 40 steam engines. 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 allows steam engines to be chained together. The heat exchanger exchanges heat between a heat connection and water to produce steam . 20. Now you have 0 waste of fuel. Create an account to follow your favorite communities and start taking part in conversations. A compendium of the most common Factorio game facts, such as build ratios, tips/tricks, . Hence, each water pump can support a maximum of 40 steam generators. All rights reserved. Use the lake west of your copper mine. u/asdjfsjhfkdjs calculated the convergents of 500:291, and found that 7 : 4 and 55 : 32 are both fairly accurate approximations. Yes, there is also a maximum throughput for water that depends on the distance the . A heat exchanger produces 10 MJ a second, therefore it produces 10MJ / 0.097MJ = 103.0927835 steam per second. So the 50,000C are enough to heat up 103 units of steam per second, since 50,000 / 485 = 103.09. Create an account to follow your favorite communities and start taking part in conversations. factorio offshore pump heat exchanger ratio The steam produced is exactly 500C hot, even if the exchanger is hotter. Each offshore pump outputs 1200 units of water per second. I have been reading all about Nuclear power so I can convert my factory. I think it is easiest to just have an abundance of storage tanks for the steam. The technical implementation details of Factorio's pipe system still have some room for improvement. 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. Looking for efficient setups? by mrvn Fri Nov 29, 2019 4:41 pm, Post where game_day is the number of seconds in the game day which is 25000/60 s by default. Reddit and its partners use cookies and similar technologies to provide you with a better experience. 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). Are there enough steam generators (boilers, heat exchangers)? 120 MW ^Note: Pumps, Steam Turbines and Power are approximate for easier build ratios. Also, the optimal ratio is: 1 offshore pump / 14 boilers / 10 steam engines is that 10 for each boiler? 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. 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. This layout produces 40 MW output ( 1 SRE ). For more information, please see our In theory, there is no difference between theory and practice. Optimal ratio is 1 offshore pump for every 20 steam turbines; or, 25 offshore pumps for every 291 heat exchangers. My own personal Factorio super-power - running out of power. These fuel cells are then burned in a nuclear reactor to create heat. by gGeorg Sat Dec 07, 2019 1:00 am, Post The steam produced is exactly 500C hot, even if the exchanger is hotter. Steam engines will automatically adjust their power production and steam usage based on the current demands of the electricity network. Electricity has to be produced before it can be transferred to consumers over the electric system. In a vanilla game that's. what, 1k science a minute? It does not require electricity or fuel to operate. Press J to jump to the feed. 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. 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.
