Abstract

Provided is a fluidized calcination furnace that reduces the uncombusted ratio at the fluidized calcination furnace outlet and thus can carry out sufficient calcination while preventing occlusion of a preheater even when pulverized coal which has poor combustion properties such as coal and coke are used as fuel by means of computational fluid dynamics calculations on the basis of actual furnace shape and operating conditions. The present invention is a fluidized calcination furnace (1) which has a cylindrical furnace body (2) with the axial center direction in the vertical direction has a pulverized coal blow in line (3) through which fuel is blown into the furnace body (2) a raw material chute (4) through which cement raw material is introduced and at least one forced air introduction pipe (5) that sucks in air for forced air connected to the side parts of this furnace body (2) and has an air blow in opening (6) for fluidization through which fluidization air is blown into the furnace body (2) disposed in the bottom of the furnace body (2). The blow in opening for the pulverized coal blow in line (3) is below the inlet opening for the forced air introduction pipe (5) and is disposed above the air blow in opening (6) for fluidization.
