【Abstract】 The ash circulating ratio in CFB boiler has an effect not only on combustion but also on heat transfer. The heat transfer coefficient for furnace is the key datum of its thermal calculation. This paper proposes a calculating empiric formula of heat transfer coefficient for furnace, based on the measured data in site and references. It has been demonstrated to be true on several CFB boilers.更多还原
