Catalytic combustion apparatus and method

摘要

A self-heating type catalytic combustion apparatus and method for igniting catalyst mass effectively within a short period of time and under a clean state and for realizing pleasant heating and having a long life-span of catalyst mass. The self-heating type catalytic combustion apparatus includes: a conductive self-heating type catalyst mass having electrodes for supplying power source to the catalyst mass; electrically energizing system for energizing electrically the catalyst mass; reaction gas supply member for supplying reaction gas comprising fuel and air to the catalyst mass; temperature detection circuit for detecting temperature of the catalyst mass; and control circuit by which the electrically energizing means are so controlled at the time of ignition that the catalyst mass is preheated to a predetermined temperature and the reaction gas supply member is so controlled that the reaction gas is supplied to the catalyst after a temperature detected by the temperature detection means reaches to the predetermined preheating temperature.
