Abstract

The invention provides an optimization method of the operation of a power station boiler. The optimization method comprises the following steps: obtaining optimal operating condition data; obtaining current operating condition data of a thermal power generating unit; when safety index parameters, stability index parameters and environment-friendly index parameters all meet pre-set conditions, obtaining a power generation cost of a current operating condition; if finding an operating condition which is the same as the current operating condition from the optimal operating condition data, obtaining an optimal operating condition power generation cost of the current operating condition; if not finding, adding current operating condition parameters into historical operating condition data; if the power generation cost of the current operating condition is less than or equal to the optimal operating condition power generation cost, sending out a first alarming prompt; otherwise, obtaining an adjusting value and obtaining a cost loss; sending out a second alarming prompt and outputting the adjusting value; continuously adjusting an oxygen amount and an air feeding amount according to the adjusting value; and when meeting a pre-set condition, stopping adjusting. The invention further provides an optimization device of the operation of the power station boiler and the stability of optimizing the power station boiler is improved.

Description

technical field [0001] The invention relates to the optimal control of a power plant boiler, in particular to an optimization method and device for the operation of a power plant boiler. Background technique [0002] During the operation of large-scale thermal power generating units, in order to realize the optimal operation of large-scale thermal generating units, it is necessary to adjust the parameters of the generating units; and supplying sufficient and appropriate air is a necessary condition for complete combustion. The excess air coefficient α at the furnace outlet is in the range of 1.15 to 1.25. Too high or too low α is unfavorable to boiler combustion efficiency and thermal efficiency. Traditional thermal power generation units generally rely on the operating experience of on-site operators to determine an optimal operating parameter, which has certain limitations and arbitrariness. As a result, due to the lack of experience of the operating personnel, the operat...
