Abstract
In allusion to a 700 MW tangentially fired utility boiler after low NOx combustion transformation,a kind of self-a-daptive optimization control method for multi-coal low NOx combustion for the boiler was proposed.Firstly,adjustment ex-periment on operation optimization control under various working conditions was developed for three common types of coal including mixed coal,blending combustion of mixed coal and Indonesia coal and blending combustion of mixed coal and car-boniferous coal so as to obtain optimization control parameters of various types of coal under different working conditions. Secondly,these parameters were solidified into disperse control system of the boiler unit to form operation optimization con-trol mode for the boiler under the condition of various types of coal and set one-button operating function.Finally,operat-ing crew used one-button operating function to choose corresponding operation optimization control mode according to infor-mation of practical fired coal in order to realize real-time optimization adjustment and control for the boiler.Test result of load change automatic program control indicates that the established control mode could effectively realize automatic control on load change process.Practical operational effect indicates that this method is fast and effective which could realize precise adjustment on parameters and avoid false operation as well as improve effects of optimization control and enhance adaptabil-ity of boiler load and multi-coal low NOx combustion.关键词
