Abstract

The appliance has a closed combustion chamber, an exhaust-gas tube (10a) and an air tube (11a), serving to supply combustion air, as well as a means outside the combustion chamber of recycling part of the exhaust gas for NOx reduction of the said gas, there being between exhaust-gas tube (10a) and air tube (11a) at least one overflow connection (12a) for the exhaust-gas recirculation and there being a restricting device (13) arranged downstream in the exhaust-gas tube (10a), and respectively upstream in the air tube (11a), to produce an adequate differential pressure for the defined amount of exhaust gas to flow over. <IMAGE>
