mass conservation principle and coal combustion chemical analysis
a fired coal quality monitoring model for utility boilers based on flue gas components was established by using the relationship between composition characteristics of coal elements as received and flue gas components.Through measuring the operational parameters of boiler and coal mill
and combing with the model calculation
this paper realized real-time online monitoring of fired coal quality and calorific values.The practical results show that
the relative error between the elements content calculated by the above model and that from the measurement is within ±5%
indicating the model this paper built satisfies the engineering application requirements.
