Abstract

A 220t/h circulating fluidized bed boiler is selected as a research object, the heat loss of the circulating fluidized bed boiler is studied by numerical simulation while the three major parts including the furnace body of the circulating fluidized bed boiler ,cyclone separator and rear smoke channel are seen as a core of the research. The surface temperature of the boiler is got by simulating the process of heat transfer about thermal insulation materials of boiler entity. The three major parts of heat loss about the circulating fluidized bed boiler is calculated by calculative formulas of heat loss and relevant parts of the surface area which is got from the specification about the design of boilers. The three parts of the surface temperature which is get from simulating respectively are: the surface temperature of the parts of furnace is 48.5℃,the surface temperature of the parts of the cylinder about cyclone separator is 94.46℃,the surface temperature of the parts of the vertebra is 97.88℃,the surface temperature of the rear smoke channel is 48.90℃.Each part of the heat loss respectively are:128.706KW,76.359KW,57.069KW.
