摘要： A powdery fuel combustion apparatus disposed on furnace side plane (7) of vertical square body type furnace in which a vertical plane passing through a fuel jetting directional axis (8) does not cross the furnace side plane orthogonally, and thus the workability of furnace wall tubes and burner panel, and the maintainability of burner nozzle are improved. The apparatus includes a burner nozzle (1) that is formed such that the nozzle has right and left non-symmetrical shapes, with respect to a vertical plane passing through axis (8). Also, the nozzle has a tip portion opening lying in an opening plane (2) which coincides or is parallel to the furnace side plane (7).

摘要： A support structure supports a fluidized bed firing boiler disposed within a cylindrical pressure vessel and operated while the inside of a fluidized bed furnace is kept pressurized. A main body of the pressure fluidized bed firing boiler disposed within the pressure vessel is divided into a suspended section suspended from a support beam disposed at an upper interior portion within the pressure vessel, and a bottom-supported section supported by a support beam disposed at a lower interior portion of the pressure vessel. Also, a metallic expansion joint in the form of an undulated plate is provided at a point of engagement between the suspended section and the bottom-supported section.
