Abstract
Fluidized bed as a coal combustion boiler has a practical application, but, there is not an example of which gas like helium as a cooling medium flow in a thin tube with diameter of 6 mm like a stirling engine and necessary data for selecting the medium of fluidized bed and estimating the heat transfer coefficient. Specially, it is difficult to correctly estimate the radiation effect concerned with the heat transfer coefficient in case of interposing the heat transfer tube at 800 [degree]C in the high-temperature fluidized bed at more than 900 [degree]C. Therefore, for investigating the thermal characteristics when the temperature of pipe itself is at high temperature, in the gas combustion fluidized bed in which alumina particle as fluidized medium is filled, the cooling tubes by using carbonic acid gas as a cooling medium was interposed, heat transfer coefficient was measured, radiation effect was clarified by experiment, and characteristics of the gas combustion and of the exhaust gas of fluidized bed when gas is used for a fuel was investigated. 13 refs., 12 figs., 1 tab.
