The heat exchanger exchanges heat between a heat connection and water to produce steam.

Heat exchangers produce ~103 steam with a temperature of 500°C every second.

Heat exchangers will not produce steam until they reach 500°C. The steam produced is exactly 500°C hot, even if the exchanger is hotter. Heat exchangers have a heat capacity of 1 MJ/°C. Thus, they can buffer 500 MJ of heat energy across their working range of 500°C to 1000°C, and require 485 MJ of energy to warm up from 15°C to 500°C when initially placed.

Calculating steam production rate

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 500°C steam). This means a single unit of 500°C 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.

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. To heat up 1 unit of water 1 degree, 200 joules are needed, so the heat exchanger is heating up water by 50,000°C in total. But the water only gets heated up from 15°C to 500°C, so by 485°C. So the 50,000°C are enough to heat up 103 units of steam per second, since 50,000 / 485 = 103.09. Since steam is produced from water in a 10:1 ratio, this also means that 10.3 units of water are consumed per second.
