With the application of turbine-boiler deep coupling system technology in domestic coal-fired power plants

some scholars have carried out theoretical researches on the optimization and integration of the turbineboiler deep coupling system. In the practical application of the turbine-boiler deep coupling system

the research on how to accurately calculate coal consumption through experiments is still rare. In this paper

the performance test method for the unit suffering deep coupling of boiler and turbine is analyzed

including general situation of the turbine-boiler deep coupling system

test and measurement items

waste heat utilization income classification

boiler efficiency calculation

turbine heat rate calculation and unit standard coal rate calculation. Two kinds of calculation methods for classification and treatment of the boiler waste heat utilization income are put forward. The test results show that

the coal consumption obtained by the above two calculation methods are consistent

and the relative deviation value of power supply coal consumption between the two calculation methods is 0.14%.
