ら有用視されている。Main engines used in cogeneration systems that have been attracting attention in recent years include gas engines, diesel engines, and gas turbines. Both the gas engine and diesel engine mentioned above have high power generation efficiency, but in a cogeneration system that uses a gas turbine as the main engine, in addition to electricity, steam is obtained from a waste heat boiler that uses waste heat from the gas turbine. Therefore, it is considered useful.

へ供給している場合が多い。However, in general, the steam pressure generated by a cogeneration system is said to be higher than GATG, but if there is no special utility such as a steam absorption double-effect refrigerator, high-pressure steam that is not originally needed can be supplied. A cogeneration system that does this is unreasonable. In other words, the conventional cogeneration system has 8at
In many cases, high-pressure steam with a pressure of up to 300 g is reduced in pressure and supplied to low-pressure process equipment at the end.
