を用いて冷却下る必要がある。By the way, gas turbine generators use natural gas to generate electricity using high-temperature gas that is combusted in a combustor. Law is being rotated. Due to the increase in natural gas supplied to the combustor due to the increase in the load of gas turbine power generation, the combustor becomes hot, and it is necessary to control the combustion gas supplied to the combustor, and it is necessary to cool the combustor. In order to do this, it is necessary to use steam from an exhaust heat recovery boiler that utilizes the exhaust heat of high-temperature gas from a single-gas turbine generator, or steam from a steam turbine generator to cool it down.
