Claims (1)

[Claims for Utility Model Registration] 1. In a device in which heat transfer tubes are disposed within a fluidized bed to recover heat within the bed, the angle formed by the axis of the tube with respect to the vertical direction with respect to the splash zone of the fluidized bed. This is a fluidized combustion device in which intrabed heat transfer tubes are arranged vertically so that the angle is within approximately 15°. 2 Utility Model Registration Scope of Claim 1. The fluidized bed combustion apparatus according to claim 1, wherein the angle formed by the axis of the tube body of the intrabed heat exchanger tube is approximately 0°, and the tube body is positioned approximately vertically.
