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

Complexity parameter c2, fluctuation complexity parameter cf and algorithm complexity parameter c ( n ) have been adopted to analysis pressure fluctuation signals from a gas - solid fluidized bed, the variation of the three complexity parameters with gas velocity from fixed bed, bubbling fluidization to turbulence fluidization are studied, then compared in order to characterize regime behaviors. it is demonstrated that there exists a phenomenon named " recorded " in the regime transition from fixed bed to bubbling fluidization, the three complex parameters are believed to be a new technique for flow regime identification
結果表明，起始流化至鼓泡態轉變的過程中，復雜性參數表明氣固體系會進行一種所謂的「重構」現象，這與用k熵表徵起始流化態至鼓泡態之間變化時所得到的結果相一致，並能明確地指示固定床、鼓泡流化及湍動流化等不同流態之間的轉變過程，為流型識別提供了新思路。 -
