Catalytic reaction heater

Abstract

A catalytic reaction heater includes a plurality of catalytic reacting sections for generating a high-temperature gas based on a catalytic reaction of fuel and oxygen, and a plurality of heat exchanging sections for increasing the temperature of a circulating heating medium based on heat exchange between the heating medium and the gas. The catalytic reacting sections and the heat exchanging sections are alternately and serially disposed along a flowing direction of the gas. A supply amount of the fuel and oxygen supplied into an upstream end catalytic reacting section is set to a value exceeding a maximum consumable level in this upstream end catalytic reacting section.
