Patent ID: 7618255

Claim:
A catalytic combustion apparatus, comprising: a catalytic oxidizing reactor having a gas treatment inlet for a gas to be treated, an oxygen gas inlet for an oxygen-containing gas, and a non-combustible gas inlet for a non-combustible gas, and an oxidized gas outlet for an oxidized gas; a heater for heating one or more of the gas to be treated, the oxygen-containing gas and the non-combustible gas; wherein the catalytic oxidizing reactor comprises a catalyst bed for oxidizing the gas to be treated; a condenser having an inlet connected to the oxidized gas outlet of the oxidizing reactor, and an outlet for a condensate; and a pH meter for measuring a pH of the condensate; wherein the pH meter is related to a temperature controller for controlling the temperature of the heater; wherein the temperature controller changes the temperature of the heater in response to the pH of the condensate measured by the pH meter.
