II华中科技大学硕士学位论文AbstractAffected by the scarcity of coal resources and transport capacity deficiency of coal markets in China, the current situation that most power plants in China burn blended coal to replace designed coal can’t be avoid. However,due to coal fired boiler is designed for specific coal type,the change of coal type can bring adverse effect to the economics and the security of boiler’s , how to implement the mix-burning ofdifferent coal types effectively and ensure plant boiler’s security, economic, environmental and other indicators meeting the requirement of power production even achieving the best is animportant subject for burning blending coal power model of power coal blending is a effective method to instruct power plant burning blending coals reasonably. For power plants in southeast coastal area always burn blending posted of bituminous coals and Indonesian coals to replace designed coals,this article makes the research of power coal blending model on the basis of experimental of all, coal properties routine analysis, thermogravimetric experiment, drop tube bustion experiment, and melting characteristics analysis are done as the research objects of 4 types of bituminous coals,3 types of Indonesia coals and 24 types of blending posed of liner additive character of blending coal quality is tested with t test temperature, burnout discriminate index and ash fusion point are chosen to be indexestoanalyze the ignition characteristicthe burnoutcharacteristic and the melting characteristic of blending , the power coal blending prediction model is established by using BP work to predict blending coals’ characteristics,and the performance of the model is to choose the important parameters of BP work also be , the problem that how to implement multi-objective function optimization in thepower coal blending optimization modelis solved byM
