    摘要： A combustion method applied to a water-tube boiler and a regenerator of an absorption-type refrigerator includes a concentration ratio adjusting step of adjusting a concentration ratio of nitrogen oxides, carbon monoxide, and oxygen in a gas from a gas generation source to a predetermined reference concentration ratio, and a hazardous-substance decreasing step of decreasing nitrogen oxides, using an oxidation catalyst having characteristics of decreasing the concentrations of nitrogen oxides and carbon monoxide on a secondary side to substantially zero when the concentration ratio on a primary side is set to be a reference concentration ratio, in which the concentration ratio adjusting step detects the concentration of oxygen on the secondary side of the oxidation catalyst to control the concentration ratio so that a detected oxygen concentration becomes a set oxygen concentration substantially close to zero. According to the combustion method, the emission amount of nitrogen oxides can be decreased to close to zero as much as possible, and the emission amount of carbon monoxide can be decreased to a permissible range. Further, the control of a concentration ratio can be performed stably by detecting the concentration of oxygen.
