COMBUSTION APPARATUS FOR FUEL GAS, AND COMBUSTION METHOD FOR SUCH A GAS

摘要

The invention concerns a combustion apparatus (1) for a fuel gas, comprising: a metal body (2), forming a heat sink, wherein is arranged a flow path (3) from a supply intake (4) to an evacuation outlet (5); a member controlling (6) said fuel gas flow rate; a member (26) for the admixture of primary air with a fuel gas flow in gas phase, to obtain a combustible mixture; a combustible mixture burner (7) thermally integral with the metal body (2), the control member (6) consisting of a gas pressure reducing valve, at least partially integrated in the metal body (2), and comprising a chamber (8) for the intake of fuel gas in liquid phase under high pressure, and a chamber (9) for evacuating said gas under low pressure, at least partially in gas phase, arranged in said metal body (2), as well as a check valve (10) arranged mostly within said metal body (2).
