摘要：

To improve the performance of radiant-tube burners, which are widely used for indirect heating in industrial furnaces, we have devised a new radiant-tube burner that will improve the thermal efficiency and make the radiant tube surface temperature uniform by circulating the heat-resisting particles within the burner. In this study, we investigated the particle flow behavior in the burner tube and the operating condition of fluidization by using a three-dimensional visualized cold-model apparatus. Our research we found the following points regarding development of the combustor : (1) The circulating fluidized flow and the range of circulating fluidized flow depend strongly on particle bed height and particle diameter. (2) The pressure in the combustion tube is approximately 12kPa and the pressure oscillation is around 3.5kPa for the state of circulating fluidization.
