Abstract：The research is mainly aimed at improving the counter balance calculation of boiler thermal efficiency.This paper determine the relevant measuring points to calculate the boiler thermal efficiency based on the counter balance calculation principle of boiler efficiency and the actual situation of Nanning Power Plant.In order to make the calculation of boiler efficiency more accurate,the data in the stable period is screened for research to avoid the instability of boiler efficiency caused by data jump caused by uncertain factors.The online real-time calculation of the calorific value data of the coal quality of the power plant,which is the low calorific value of the fuel,is carried out to reduce the error and time lag caused by offline manual measurement and manual filling.
