METHOD FOR SINTERING PARTICLE AGGREGATE

摘要

PROBLEM TO BE SOLVED: To provide a method for sintering particle aggregate capable of attaining sintered particle aggregate of high strength while restricting an increase in consumption of heat energy and further capable of improving gaseous state discharged from inside a fluidized bed furnace. SOLUTION: A sintering segment 6 with its upper part being connected to a gaseous combustion segment 8 of a fluidized bed furnace through a communicating pipe 7 is installed near the fluidized bed furnace. Particle aggregate is fed into the sintering segment to heat it up to a high temperature with a burner 9 and the material is sintered. Combustion gas of the burner 9 is supplied to a gaseous combustion segment 8 through the communicating pipe 7 and gas agitation in the furnace is promoted, so that CO contained in the discharged gas of the fluidized bed furnace can be reduced.
