Abstract:
A catalytic combustion heater comprising: a container forming a fuel gas passage; heat-receiving fluid passages in which a heat-receiving fluid flows, said heat-receiving fluid passages being disposed in said fuel gas passage; a catalyst-based heat exchanger for heating a heat-receiving fluid by a reaction heat of a fuel gas, said heat exchanger being disposed in said fuel gas passage and having catalytic layers that are provided on outer peripheries of said heat-receiving fluid passages and cause an exothermic reaction upon contact with the fuel gas; and heat amount changing means for changing an amount of heat to be supplied to the heat-receiving fluid flowing in respective portions of said heat-receiving fluid passages, in accordance with a variation in phase of said heat-receiving fluid, such that a portion of said heat-receiving fluid passages in which the heat-receiving fluid flows during a variation in the phase of the heat-receiving fluid receives a greater amount of heat than a portion of said heat-receiving fluid passages in which the heat-receiving fluid flows without a variation in the phase of the heat-receiving fluid.
