FUEL PURGE SYSTEM, SYSTEM CONTAINING A FUEL PURGE SYSTEM AND FUEL PURGE SYSTEM

摘要

1. System (100) containing a source of fuel gas (140, 210), circuits (202, 204, 206, 208) for fuel gas, gas control valves (165, 170, 236, 238, 240, 242), each of which is associated with one of the circuits (202, 204, 206, 208) for fuel gas and which control the flow of fuel gas supplied to these circuits from a source (140, 210) of fuel gas, and a system (175, 200) of purging fuel, intended for selective purging of those circuits (202, 204, 206, 208) for fuel gas into which the supply of fuel gas from the source of fuel gas is stopped a.2. System (100) according to claim 1, wherein the purge system (200) comprises a bypass valve (256, 260) connected bypassing at least one of the gas control valves (165, 170, 236, 238, 240, 242), moreover, the opening of the bypass valve, when the specified at least one of the gas control valves (165, 170, 236, 238, 240, 242) is in the closed position, ensures the passage of a predetermined amount of fuel gas into the inactive circuit for fuel gas. System (100) according to claim 2, wherein the flow of said predetermined amount of fuel gas into an inactive circuit for fuel gas maintains a positive fluid flow in said circuit. System (100) according to claim 2, in which the fuel purge system (200) further has a fuel gas opening (185, 258, 262) that restricts the flow of fuel gas supplied from the fuel gas source (140, 210) to the inactive circuit fuel gas. 5. System (100) according to claim 1, in which the fuel purge system (175, 200) is further configured to selectively purge purge air of those circuits (202, 204, 206, 208) for fuel gas�
