できる優れた効果を奏し得る。According to the fluidized bed container front wall upper pipe side corner portion structure of the pressurized fluidized bed boiler of the present invention, the fluidized bed container is provided with the ceiling wall outlet pipe side above the front wall outlet pipe side. In the configuration, at the upper left and right positions of the front wall, a front wall outlet pipe side communication port communicated with the front wall outlet pipe side and a front wall outlet pipe side communication port are communicated with the side wall inlet downcomer pipe. Side wall inlet precipitation pipe communication port that is open toward the front wall, the ceiling wall outlet pipe side joint part that can fixedly support the ceiling wall outlet pipe side above the front wall outlet pipe side communication port, and the side wall outlet pipe toward the rear Since the corner block having the side wall outlet pipe side joint portion capable of fixedly supporting the side portion is provided, the fluidized bed container can be easily assembled only by connecting the communication ports and the pipe side joint portion. In addition, the corner block is connected to the front wall outlet pipe outlet and the ceiling wall. Since the pipe joint part is formed integrally with the upper and lower parts in advance, the strength of the front wall upper pipe corner portion can be increased, and the excellent effect of safely suspending and supporting the fluidized bed container can be obtained. .
