Method for optimizing combustion of biomass furnace

Abstract

The invention relates to a method for optimizing combustion of a biomass furnace. At present, the online optimization can not be carried out according to the real-time change condition of the combustion of the biomass furnace. The method comprises the steps of: firstly collecting operating parameters of the biomass furnace and relevant characteristic indexes characterizing a combustion state of the biomass furnace, and establishing a database; secondly, selecting data as modeling data aiming at the given biomass furnace, wherein the data comprises conditions of feeding speeds of different biomass fuels; modeling aiming at the modeling data by adopting a least square support vector machine method, establishing a model between the characteristic indexes of the combusting state of the biomass furnace and each operating parameter of the furnace, and by using an ant colony optimization algorithm and combining with the established model, optimizing the configuration of the combusting parameters of the biomass furnace aiming at biomass fuel corresponding to the model and combusting characteristic indexes or index combination of combusting states of different biomass furnaces. According to the method provided by the invention, the optimizing efficiency and the comprehensiveness of the biomass furnace can be effectively improved, so that off-line optimization can be implemented and online real-time combustion optimization is also carried out.
