VERFAHREN ZUR SPEISUNG EINES KATALYTISCH WIRKENDEN BRENNERS MIT ERDGAS UND VORRICHTUNG ZUR DURCHFÜHRUNG DIESES VERFAHRENS.

摘要

The distribution-pressurized natural gas is supplied via a conduit (C1) arranged in the piston (P) of an electrovalve (EV) in a nozzle (BG) of which the outlet leads to a cone (C) which provides, with the nozzle (BG), a ring-shaped opening (BA) which, connected to the atmosphere, acts as a secondary nozzle for injecting air into the gas flow. The cone (C) is followed by a cylindrical element (S1) then by an abrupt widening (BC) section (S2) which opens into a heat exchanger (EC) which is in contact with a substrate impregnated with a catalytic material (MC) which oxidizes fuel gas. A small amount of air is sucked up by the widening (BC) and mixed with the gas. This mixture is then treated in the exchanger (EC) up to the transformation temperature of the sulphur-containing compound and the sulphur is then oxidized.
