FUEL GAS SUPPLY SYSTEM AND PERFORMANCE OPTIMIZED OPERATION FOR THE SYSTEM

摘要

PURPOSE: A fuel gas supply system and a performance optimization operation method thereof are provided to include stable load change corresponding to sudden load change of a high pressure gas injection engine. CONSTITUTION: A fuel gas supply system comprises a fuel supply line(L1) and a return line(L3). The fuel supply line supplies fuel to a high pressure gas injection engine(1) through a high pressure pump(3) and a high pressure vaporizer(5). The return line returns fuel to a suction drum by being branched from the fuel supply line.
