FUEL GAS CALORIE ESTIMATION DEVICE, FUEL GAS CALORIE ESTIMATION METHOD, AND PROGRAM

摘要

A fuel gas calorie estimation device equipped with: a fuel gas flow volume acquisition unit that acquires the flow volume of a fuel gas flowing into the combustor of a gas turbine; a state quantity acquisition unit that acquires the state quantity of the gas turbine; a storage unit that stores the power generation efficiency, which includes an efficiency correction coefficient corresponding to the state quantity; and a fuel gas calorie calculation unit that calculates the fuel gas calories on the basis of the fuel gas flow volume, the state quantity, and the power generation efficiency obtained from the efficiency correction coefficient in accordance with that state quantity.
