Although steam turbines can be connected to boilers for use in conventional steam power, the steam produced by boilers is much lower temperature than the steam produced by heat exchangers. This results in the steam turbine working at much lower than full capacity. Because of this, it is not suggested to replace steam engines with the much more expensive steam turbines for this use.
- Heat exchanger heats 15°C Water to 500°C Steam;
- It takes 0.2kJ of burner energy to raise 1 Water 1°C;
- Steam is consumed by Steam turbines at a rate of 60 Water/s;
- (500 - 15) × 0.2 × 60 = 5820kW, or 5.82MW.
