  3. Abstract : in the internal circulating fluidized bed, there exist the moving zone, fluidizing zone and heat transferring zone with different fluidized air velocities. the convection heat transfer coefficient of immersed tube in the heat transferring zone is impacted by the velocity of the moving zone nearby and its data and change trend are obviously different with those of the common bubbling bed. the maximum heat transfer coefficient is evidently higher than that of the bubbling bed. as the bed materials have not been fluidized in the heat transfer zone, the coefficient has increased highly. the curve of that changes gently, feasilble to control the combustion intensity in the fluidizing zone
