ABSTRACT:
A regenerative thermal oxidizer having regenerative heat exchangers includes a heat exchange column formed of a body which defines at least one entire flow passage through the heat exchanger. The heat exchange column assists in purging residual gas to be cleaned from the heat exchanger prior to that regenerative heat exchanger moving into a mode where it receives the cleaned gas. This reduces inadvertent emissions of gas to be cleaned to the environment. In one embodiment, a monolithic body includes all of the flow passages. In a second embodiment, a plurality of blocks are utilized to form the heat exchanger column. In a third embodiment, a number of cylindrical tubes are utilized. The heat exchanger columns preferably have 70 to 80 percent of their surface area used as the flow passages.
