Against the typical subcritical 600 MW unit boiler in a power plant

a B/S structure based decision-making system for mixed coal combustion was established.This system composed of five functional modules

such as coal combustion data management and coal property evaluation

boiler equipment information management

power coal blending decision

system help and user management.It can predict the feasibility of burning new coal

comprehensively analyze the safety and economy of co-firing mixed coals with different blending proportions

and provide suggestions for device operation.This decision-making system for mixed coal combustion was applied on a subcritical 600 MW unit boiler.The optimal coal blending scheme and its prediction results were obtained.The actual co-firing effect agreed well with the prediction conclusion.Furthermore

problems like serious slagging

coal drop pipe blocking and explosion in pulverizing system were solved at the same time.
