In view of the deficiencies of carbon content device in sampling and measurement of fly ash by weightlessness method,the measurement accuracy and sampling stability of carbon content device in fly ash are improved by plugging and wear-resistant technology.The device was applied to the intelli-gent combustion system of 660 MW unit boiler,and the combustion state in the furnace was reflected by accurate measurement of carbon content in fly ash,which ensured the correctness of combustion op-timization control model prediction.The results show that the error between the actual and predicted values of carbon content in fly ash is kept within a small range,and the maximum error is less than 0.015%.The field operation results show that the average carbon content of fly ash decreases from 2.1%to 1.5%after the combustion optimization system is put into operation,and the boiler efficiency increases by 0.21%.
