FUEL GAS SUPPLYING APPARATUS OF SHIP ENGINE FOR HIGH PRESSURE

摘要

The present invention relates to a fuel gas supplying apparatus of ship engines for high pressures allowing the reduction of gas consumption since the cool-down of a fuel gas supplying apparatus can be maintained in a standby mode as natural gas (NG) can be sent to a supplementary engine for continuous circulation of LNG when the NG, which is fuel, is supplied to a cyclic engine and a supplementary engine for high pressures. The present invention comprises; a storage tank (10) to store LNG; and an intake drum (20) to intake LNG from the storage tank (10); and a carburetor (50) to vaporize LNG in the intake drum (20) by transferring the LNG through a booster pump (30) and a high-pressure pump (40) wherein; the NG vaporized while passing through the carburetor (50) is supplied through a transfer pipe (51) and a bypass pipe (52) to the cyclic engine (100) and the supplementary engine (200), respectively; and the bypass pipe (52) has a structure sequentially provided with; an orifice (53) for reducing pressure; and an adjustment valve (60) to adjust the degree of opening so that NG is supplied to the supplementary engine (200) under a condition of adjusted pressure; a high-pressure tank (70); and an adjustment valve (80) to adjust the degree of opening by sensing the pressures of NG passing through the high- pressure tank (70); and a heat exchanger (90) to raise a temperature of NG.
