Description of the Related Art Conventionally, heating of feed water to a boiler in a thermal power plant is performed by steam extracted from a turbine that drives a generator. In general, a so-called regeneration cycle is configured as a thermal cycle, and a large-scale facility is generally configured as a reheat regeneration cycle in consideration of reheating. In the regeneration cycle, steam that has not been completely completed in the turbine is extracted from the turbine, guided to a feed water heater, and the feed water heater is used to heat the feed water to the boiler. That is, it is constituted by one machine and one can (one turbine, one boiler) equivalent to pressure, and does not have an attached boiler with different pressure.

And these are about 32 as shown in FIG. 3 of the boiler.
Corrosion of the high-temperature heat transfer surface mainly with a heater of 0 ° C or higher,
This makes it difficult to design high pressure and high temperature boilers. Therefore, in the power generation using the waste boiler, the power generation efficiency is 10 to 20%.
This is significantly worse than about 40% of general thermal power plants.
