Abstract

The invention discloses a boiler combustion multi-constraint multi-objective optimization expert system and its optimization method. The system includes a DCS control system module, an industrial coal type analysis module, an environmental pollutant monitoring module, an approximate case query unit, a historical database, and a boiler combustion model Library, boiler optimization expert system server program and man-machine interface. The boiler combustion multi-constraint multi-objective optimization expert system and its optimization method proposed by the present invention can realize the prediction of boiler combustion thermal efficiency and pollutant discharge; at the same time, reasoning and query are carried out according to the combustion model library, and the intelligent algorithm of the boiler optimization expert system is adopted , can find the parameter setting scheme to achieve the best working condition of the boiler, and then adjust the boiler operating state through DCS to realize the overall optimization of boiler combustion.

Description

technical field [0001] The invention belongs to the technical fields of energy, environmental protection, information, etc., and relates to a boiler combustion optimization expert system, in particular to a boiler combustion multi-constraint multi-objective optimization expert system; meanwhile, the invention also relates to an optimization method for the above-mentioned optimization expert system . Background technique [0002] During the combustion process of boilers, most of the factors affecting the combustion thermal efficiency and pollutant emissions are the same, but the specific requirements for each factor are often contradictory. Among the existing methods for optimizing the air-to-coal ratio, some can improve the thermal efficiency of combustion, but increase the discharge of pollutants and aggravate environmental pollution; some focus on reducing environmental pollution while ignoring the thermal efficiency of boiler combustion. [0003] The DCS control and adju...
