With the in-depth promotion of energy saving and emission reduction work,the thermal power enterprises began to actively recycle all kinds of exhaust steam,of which the typical exhaust steam recovery methods are thermal deaerator exhaust steam recovery and boiler fixed-row expansion vessel exhaust steam recovery.However,when calculating the efficiency of waste heat recovery from exhaust steam of extractive steam reheat type tur-bine generator sets,some enterprises simply convert the recovered heat into standard coal for calculation without considering the loss of cold source,which results in a large error.By analyzing and correcting the calculation process of specific exhaust steam recovery cases,it aims to illustrate that thermal power plants need to combine their own process flow to re-move the cold source loss during turbine operation from the exhaust steam recovery benefit,so as to ensure the accuracy of the recovery benefit calculation.
