Abstract


Of pulverized coal power plant boiler widespread phenomenon the fuel coal difference deviation from the design coal , serious impact on the the crew economic and security . For the study, and the problems of its site , such as the stability of ignition , a 600MW supercritical unit boiler ash and fly ash with high carbon content and reheat steam temperature low study . According to strengthen the theory of ignition and complete combustion characteristics of supercritical once-through boiler , run to adjust the angle of the corresponding measures ; laying refractory belt rehabilitation programs ; numerical simulation method to simulate the proposed scheme of furnace combustion process , fire , burn and reheat steam temperature change . Plant subsequent transformation practice show that the proposed scheme can help to solve the site problem .
