A thermal efficiency model in operation of boiler mixedly burning blend coal has been established
including the one dimentional model of furnace
the lumped parameter model of the covection heating surface
and the calculation model of boiler's thermal efficiency.The emulation calculation of boiler for supercritical 600 MW unit in one power plant shows that the carbon content in fly ash decreases
the flue gas temperature increases
and the thermal efficiency of boiler decreases
as the coal quality factor Fz to be increased;the emulated value of carbon content in fly ash and the temperature of discharged flue gas tally better with the actual values in operation
the tendency predicted by the thermal efficiency model of boiler being accurate
