A methane catalytic combustion boiler for obtaining hot water for household and industrial uses, such as room heating, sanitary services, heat transfer in industrial processes is described. The boiler includes a container for the combustion catalyst, which consists of pure or supported metal oxides, a heat exchanger between the combustion gases and the water to be heated, a system for starting the methane combustion and a system for controlling the combustion.

Methane catalytic combustion boiler for obtaining hot water for household and industrial uses by catalytic complete combustion of the methane contained in an air/methane mixture fed to it, said mixture containing oxygen in an amount corresponding at least to the stoichiometric amount necessary for said complete combustion of methane, comprising a catalyst container containing a non-fluidized bed of a catalyst consisting of a metal oxide or a mixture of metal oxides selected from the group of the oxides of Cr, Mn, Fe, Co, Ni, Cu, Sn and Zn maintained at a temperature of less than 750°C.; a metal heat-sink means supported on the outer surface of said catalyst container for heat exchange between the combustion gases and the water to be heated; an electrical ignition system placed near the inlet of said air/methane mixture for starting the methane combustion; and one or more thermocouple means sunk in the catalyst bed which signal a system blocking the methane feed if the temperature falls below the ignition limits of said air/methane mixture.
