FUEL GAS FEEDER FOR GAS INTERNAL-COMBUSTION ENGINE

摘要

PURPOSE:To feed fuel safely to an engine while self-conditioning the fuel gas temperature by providing a valve for passing the compressed fuel gas prior to starting in a bypass connecting between the vicinity of internal-combustion engine arranged in a compressed fuel gas feed path and the suction side of compressor. CONSTITUTION:The piping A in the downstream of a drain separator 24 is branched into the bypass system piping B returning to the mist separator 20 and the internal-combustion engine system piping C to be coupled through a heatexchanger 22 with the internal-combustion engine 26. The fuel gas returning from the piping B to the gas inlet 29 is heated excessively because of the friction heat of compressor, thereby it is passed through an after-cooler 28. Heat exchanger volume Q will decrease as the flow G of the fluid to be heated decreases to suppress the temperature rise of said fluid while since the delivery fuel gas of compressor is employed as the heating fluid of heatexchanger 22, self-conditioning function for preventing over heat is provided to the heatexchanger 22.
