Abstract
Multiple heat-receiving fluid passages, through which heat-receiving fluid flows, are arranged in layers in a fuel gas passage provided in a container. Multiple fins, on which an oxidation catalyst is carried, are provided on outer peripheries of the heat-receiving fluid passages. A feed port for combustion support gas is provided at one end of the fuel gas passage, and multiple combustible gas feed ports are provided in a wall of the fuel gas passage. Combustible gas is separately supplied to the respective layers of the heat-receiving fluid passages in accordance with a state of the heat-receiving fluid so as to suitably control a heat release value. Especially in the intermediate layer where the heat-receiving fluid is at its boiling point and thus exhibits a low heat transfer resistance, more combustible gas feed ports are provided than in the other layers. As a result, more fuel is supplied, the heat release value is increased, and the heat exchange efficiency is enhanced.
