<p>PURPOSE:To enable to remove hydrogen chloride and sulfur oxide contained in combustion gas, simultaneously, easily, and efficiently, by adding calcium compound to the gas, in case that a material to be burnt, containing chlorine content and sulfur content, is burnt in a combustion furnace. CONSTITUTION:When a material to be burnt is burnt, first of all, a calcium compound and a material to be burnt are fed into a fluidized bed part 4, respectively, from a feeder port 3 on the side wall of a fluidized bed combustion furnace 15, for instance, by the intermediary of each hopper 1 and 2. On the other hand, combustion air 7 is fed into the furnace 15, passing through an air inducing chamber 8 and an air dispersing plate 9. With such an arrangement, ion oxide and hydrogen chloride generated in the fluidized bed part 4 during combustion are absorbed by calcium compound, which is discharged from a discharge port 5 as waste absorbent. Waste gas is discharged from a discharge port 10, and dust is separated from the waste gas 12 by a dust collector 11. With such an arrangement, hydrogen chloride and ion oxide contained in combustion gas can be removed from the gas, simultaneously, easily and efficiently.</p> |
