うにしていたため、効率の悪いプラントとなつイいた。Factories in various manufacturing industries often require electricity and steam at the same time, so a combination of a non-reheat boiler and a backpressure turbine was often used as the prime mover. By the way, power demand and steam demand usually fluctuate, and if only one set of a non-reheat boiler and a back pressure turbine is provided, it is not possible to satisfy both demands at the same time. Therefore, in the past, the demand was met by providing multiple sets of non-reheat boilers and back pressure turbines, or by purchasing electricity to make up for the lack of electricity, resulting in inefficient plants.

は公知の再熱サイクルと同様であり、説明は省略する。The main steam leaving the boiler 1 drives a high-pressure turbine 2, and a high-pressure turbine generator 3 generates electricity. The steam that has done work in the high-pressure turbine 2 is superheated in a low-temperature reheater 4 and then enters a reheater intermediate ladder 6. Then, a part of the steam is taken out from the reheater intermediate header 6, brought to a desired temperature in the desuperheater 8, and sent as factory air. This temperature is set by factory air thermometer 19. On the other hand, the remaining steam is transferred from the reheater intermediate header 6 to the high temperature reheater 5.
After being heated to a specified temperature, it passes through a pressure regulating valve 9 and enters a low-pressure turbine 10. Therefore, the low pressure turbine 10 is driven and the low pressure turbine generator 11 generates electricity. Exhaust from the low pressure turbine 10 is sent to the condenser 12
The process of being introduced into the boiler 1 and thereafter being supplied as feed water to the boiler 1 is the same as that of a known reheat cycle, and a description thereof will be omitted.

That is, the sample is taken out at a temperature higher than the required temperature condition, and the temperature is lowered to the required temperature using the desuperheater 8.
