Boiler room efficiency calculation method, and a power generation end efficiency calculation method .

摘要

PROBLEM TO BE SOLVED: To provide a method for computing boiler room efficiency that can accurately determine power generation terminal efficiency even with boiler room efficiency computed by a loss method by multiplying it by turbine room efficiency.;SOLUTION: When computing the boiler room efficiency by subtracting a loss amount from a heat input amount to a boiler in a thermal power plant that generates power by guiding steam generated in the boiler 11 to turbines 15, 17, 18 and driving a generator connected to the turbines, heat input to the turbine room side viewed from the turbine room side is set as plus, while heat output from the turbine room side to the boiler room side is set as minus, and heat output from the turbine room side to the boiler room side is regarded as a loss amount of the boiler and subtracted from the heat input amount to the boiler to compute boiler room efficiency.;COPYRIGHT: (C)2012,JPO&INPIT
