Wall average heat transfer in CFB boilers - ScienceDirect
2001-10-8u2002·u2002Heat transfer to cooling surfaces is a key parameter for the control of the furnace temperature in a circulating fluidized bed (CFB) boiler. The cooling surfaces can either be vertical membrane-walls, internal tubes in the combustion chamber or tube bundles in an external heat exchanger in the particle recirculation loop; Fig. 1.This paper deals with heat transfer to the vertical membrane-wall ...
