Abstract
A method of diminishing the amount of chlorinated organics released to the atmosphere in the incineration of wastes which includes injecting calcium-based sorbents into the flue gas to react with HCl to form calcium-chlorine compounds to remove the HCl from the flue gas and prevent it from forming the chlorinated organics. The flue gas carries the sorbent from the injection zone to the reactive temperature zone quickly enough such that the sorbent is not exposed to temperatures which would degrade the effectiveness of the sorbent, the reactive temperature zone being in the range of 300.degree. C. to 900.degree. C.
