ABSTRACT:
A method of quick purging beds of a regenerative fume incinerator which is practically applicable for use in 2, 3 and 4 bed incinerators. For a very short purge period near the end of an operating time cycle, the bed being switched from receiving impure gases to discharge of clean gas is purged of impure gases by being supplied with clean gas discharged by the incinerator. The quick purging takes less than 4% of the cycle time and thus inflow of impure gases is stopped for a very brief period when this quick purge method is used in a 2 bed incinerator. When using this quick purge method in a three or four bed regenerative fume incinerator there is always at least one bed receiving impure gases. This quick purge method improves the quality of the discharged clean gas without significant loss of thermal efficiency and without significant reduction in operating capacity.
