ABSTRACT:
The present invention involves a regenerative thermal oxidation apparatus for purifying gases by thermal oxidation and for exchange of heat between inleting and outleting gases. The apparatus has a plurality of thermal chamber units, each such unit having a gate with at least one gate orifice movably located in a linear fashion against a base surface so as to alternatively align with various inlet and outlet openings. The improvement involves the use of a plurality of seals located between the gate and the openings with sufficient sealing capabilities between the gate and the openings to maintain each chamber at an elevated pressure, i.e. above atmospheric pressure, and so as to reduce leakage of gases from each of the chambers and reduce condensation during operation. The invention is also directed to the method utilizing this apparatus.
