<p>PURPOSE:To improve the regeneration rate for desulfurizers by controlling the temp. or flow rate of the used desulfurizers to be supplied to a regenerating furnace and controlling the temp. of the regenerating furnace to an adequate temp. CONSTITUTION:The temp. in the fluidized bed in a regenerating furnace 2 is detected with a temp. detector 12 for fluidized beds and when the detected temp. is higher than the temp. at which the regenerating rate of desulfurizers is good, a motor M is operated by the detection signal thereof to increase the opening of a flow rate regulating valve 13 and to increase the flow rate of used desulfurizers into the furnace 2, whereby the temp. is reduced. When the temp. of the fluidized bed is lower than the adequate temp., the opening of the valve 13 is decreased to decrease the inflow rate of the used desulfurizer, whereby the temp. is increased. A heat exchanger 14 for controlling refrigerant is provided to a connecting pipe 3 for a combustion furnace 1 and the regenerating furnace and the opening of a flow rate regulating valve 15 for refrigerant is controlled with the detection signal of the detector 12 to decrease or increase the temp. of the used desulfurizers to be supplied to the regenerating furnace, whereby the temp. in the fluidized beds in the furnace 2 is maintained at the adequate temp. The above- mentioned two means may be used in combination.</p> |
