A process is provided for substantially completely converting carbon monoxide in waste gas into carbon dioxide in a combustion chamber. This process comprises the steps of supplying fuel to the combustion chamber in an amount sufficient to maintain a temperature greater than the combustion temperture of carbon monoxide therein, feeding waste gas containing carbon monoxide to the combustion chamber, measuring the percentage of carbon monoxide in the waste gas, feeding free oxygen to the combustion chamber, exhausting the gas from the chamber, measuring the actual percentage of free oxygen in the exhaust gas, calculating an optimum percentage of free oxygen in the exhaust gas, and adjusting the volume of free oxygen being fed to the combustion chamber in an amount sufficient to produce the optimum percentage of free oxygen in the exhaust gas.

Waste gas incineration control

Activated carbon having adsorbed materials thereon is regenerated by passing a mixture of gases and/or vapors capable of exothermically reacting through the bed. The heat of reaction liberated by the reaction heats the carbon bed sufficiently to permit removal of the adsorbed materials thereon. The bed may then be further purged with an inert gas to complete the removal of the adsorbed materials.
