Abstract

In order to avoid overtemperature tube explosion of the platen superheater, the measurements of metal temperatures and the heat transfer coefficients of the platen superheater in a commercial 300 MW Circulating Fluidized Bed (CFB) boiler are conducted in this work. The measured data is analyzed and the theoretical calculation is made. On the basis, the reasonable steam flow path and the value range of heat transfer coefficient of the middle temperature platen superheater are applied for design. Furthermore, based on operation experience from several 300 MW CFB boilers, a design principle of the mass velocity and the arrangement of the platen superheater in the furnace is given.
