Abstract

PURPOSE: To effectively dry and burn muddy viscous material in fluidized bed by a method wherein sludgy coal is extruded out at constant rate in accordance with combustion state and load.
CONSTITUTION: At the sludgy coal discharge side of a screw 10b are generally equipped with two cutting impellers 13 connecting to the shaft of the screw 10b and making an acute angle to its advance side surface. The discharge side end surfaces of the impellers 13 can slidably rotate with a little gap against the inside surface of the end plate 14 of a screw casting 10a. On the end plate 14 are provided a plurality of squeezing-out holes 15 divergent toward the outside of the plate or the inside of a furnace. The holes 15 are located within the circle drawn with its center at the axis center of the screw 10b and with a radius of R1 which is about 75% of the radius R of the end plate 14. Due to the arrangement of holes described above, the cylindrical sludgy coal bars with desirable length and diameter are discharged into the fluidized bed and the constant rate supply in accordance with the combustion state and the load is made possible.
