Abstract

In a regenerative bed incinerator 10 of type wherein the direction of gas flow through the bed 14 is periodically switched via a gas switching valve 30, a controller 80 is provided to periodically activate the gas switching valve 30 to reverse the direction of gas flow through the bed 14 in response to the temperature of the cooled incinerated process exhaust gases 5 as measured by gas sensing means 90.
