PROBLEM TO BE SOLVED: To provide a fluidized bed reactor such as a fluidized bed boiler that can suppress wear of a furnace wall.SOLUTION: A fluidized bed reactor includes a furnace wall 1 defining a reaction chamber 2, and causes reaction while a fluidizing material F is made to flow in the reaction chamber 2. The fluidized bed reactor further includes furnace wall collision prevention control means 7 for preventing the fluidizing material F from colliding with a furnace wall pipe constituting the furnace wall 1. The furnace wall collision prevention control means 7 controls a course of the fluidizing material F so that the fluidizing material F does not collide with the furnace wall pipe by supplying gas into the reaction chamber 2. Namely, since the course of the fluidizing material F is controlled so as to prevent the fluidizing material F from colliding with the furnace wall pipe by using the furnace wall collision prevention control means 7, the fluidized bed reactor inhibits the fluidizing material F from coming into contact with the furnace wall pipe, so as to enable suppression of wear of the furnace wall pipe.SELECTED DRAWING: Figure 3 |
