ABSTRACT:
A method for controlling gas flow direction through a regenerative incinerator system coupled to a flow reversing valve, and for reversing the flow direction of the gas stream through the regenerative incinerator system. The regenerative incinerator system having a combustion zone and one or more heat accumulating and heat exchanging zones. The method establishes a combustion zone base temperature set-point, or T.sub.CB for referencing combustion zone temperatures, or T.sub.C 's, and an outlet base temperature set-point, or T.sub.OB, for referencing outlet temperatures, or T.sub.O 's, from the regenerative incinerator system. A switching temperature, or T.sub.S, is also established as a function of T.sub.C, T.sub.CB and T.sub.OB such that the slope of said function, i.e. dT.sub.S /dT.sub.C, is never negative over a predetermined range of combustion zone temperatures, or T.sub.C 's. The switching temperature being equal to T.sub.OB when the combustion zone temperature is equal to T.sub.CB. The flow direction is caused to reverse the flow direction of the gas stream through the regenerative incinerator system when the gas stream temperature from the regenerative incinerator system, or T.sub.O, reaches T.sub.S. In one embodiment, the slope of said function is zero when the combustion zone temperature is equal to T.sub.CB.
