ABSTRACT

According to the coal quality characteristics of a 300MW boiler and corresponding operation monitoring parameters, this paper has established coal-fired boiler optimum excess air coefficient calculation models under different conditions by using the method of the boiler counter balance, the relationship curve between the boiler load and optimum excess air coefficient has been calculated, then the optimum thermal efficiency of boiler under different conditions can be calculated. In addition, this paper analyzes the parameters that affect the operation economy of power station boiler, then the influence degree of different parameters on boiler operation can be got based on hierarchy process theory, which provides theoretical guidance for the optimal operation of boiler.
