Heat source device and method for using silver zeolite

Abstract

Provided is a new heat source device utilizing a catalytic reaction heat of silver zeolite, the heat source device including an accommodation container for accommodating the silver zeolite while ensuring air permeability, in which the accommodation container is configured to be ventilated with a mixed gas containing hydrogen, steam, and air, the accommodation container is configured as a metal cylindrical member that includes a metal ventilation structure having a mesh on a downstream side in a ventilation direction, the mesh having a mesh size finer than a particle diameter of the silver zeolite; and the cylindrical member has a double pipe structure including an inner pipe and an outer pipe, said inner pipe being a straight pipe for allowing the mixed gas to linearly flow therein.
