PURPOSE: An LNG fuel gas supply system of high-pressure and low-pressure dual fuel engines is provided to increase system efficiency with reduced energy consumption by simultaneously operating the high-pressure and lower-pressure dual fuel engines with one LNG tank.;CONSTITUTION: An LNG fuel gas supply system of high-pressure and low-pressure dual fuel engines comprises an LNG tank (101), a first control valve (102), an evaporation part (103), a second control valve (104), a mixing tank part (105), and a low-pressure gas compressor (106). The first control valve is installed in the front end of the LNG tank and is opened and closed according to the pressure of the LNG tank to supply boil-off gas. The evaporation part evaporates gas stored in the LNG tank. The second control valve is installed in the front end of the evaporation part and is opened and closed according to the methane number of the gas evaporated by the evaporation part. The mixing tank mixes the boil-off gas receiving from the first control valve and the evaporated gas receiving from the second control part. The low-pressure gas compressor makes the fuel receiving from the mixing tank use as the fuel of the engine.;COPYRIGHT KIPO 2013;[Reference numerals] (101) LNG tank; (102) First control valve; (103) Evaporation part; (104) Second control valve; (105) Mixing tank part; (106) Low-pressure gas compressor
