Abstract
For continuous combustion air control in a hazardous waste incinerator, two signals are generated which totalize the air required on a fuel supplied basis. One signal is responsive to measured totalized fuel flow and this total can include fuel flow signals which are limited to the fraction of available air which corresponds to the fuel flow. The other signal is responsive to the totalized fuel flow that is commanded for maintaining an incinerator condition. In use the signal which requires the greater air flow is selected as the actual control signal for combustion air, and this control signal is biased to increase the air flow to obtain complete combustion of the hazardous waste by a controller acting on the measured amount of oxygen in the flue gas. In this manner the combustion air is manipulated in parallel with the waste fuel and if the fuel flow is limited by the available air, the air flow is limited to match the limited fuel flow.
