The invention discloses a method for generating infrared radiation wave by virtue of combustible gas oxidization. The method comprises the following steps: a. plating a cotton-silk-shaped aluminum dioxide fiber layer with a platinum catalyst to prepare catalytic cotton; b. heating the catalytic cotton to reach 50-60 DEG C; c. enabling combustible gas to pass through the catalytic cotton, and enabling the combustible gas to be combined with oxygen molecules in air on the surface of the catalytic cotton to form an oxidation reaction; and d. radiating out infrared ray after the combustible gas isoxidized. The oxidation reaction temperature of the combustible gas is lowered by virtue of the catalytic cotton layer due to no need of ignition during use, the oxidation reaction of the combustiblegas is accelerated through the oxygen molecules in air, and the combustible gas is made to generate the infrared ray on the surface of the catalytic cotton; and with the adoption of the method, energy can be effectively saved, and safer and more reliable production is achieved.
