20140230458 | SYSTEM FOR SUPPLYING LIQUEFIED NATURAL GAS FUEL - Disclosed is an LNG fuel supply system, including: a fuel supply line connected from an LNG storing tank to an engine; a pump provided on the fuel supply line, and configured to change an LNG to the LNG in a supercooled liquid state by compressing the LNG discharged from the LNG storing tank at a high pressure; and a heat exchanger provided on the fuel supply line between the engine and the pump, and configured to phase change the LNG in the supercooled liquid state to the LNG in a supercritical state by heating the LNG in the supercooled liquid state supplied from the pump. | 08-21-2014 |
20140250921 | SYSTEM FOR SUPPLYING LIQUEFIED NATURAL GAS FUEL - The system heats glycol water using steam generated by a boiler and heating LNG using the glycol water, thereby increasing efficiently the LNG to temperature required for an engine. In addition, the system senses LNG flowing to a glycol tank using a pressure sensor, etc. when the LNG flows to the glycol tank due to pressure difference between a fuel supplying line and a glycol circulation line generated according as a heat exchanger is broken down, and outputs the flowed LNG to the outside. As a result, the glycol circulation line may be returned to original state and stability of the system may be enhanced. | 09-11-2014 |
20140250922 | SYSTEM FOR SUPPLYING LIQUEFIED NATURAL GAS FUEL - A system for supplying LNG fuel is disclosed. The system includes a fuel supplying line connected from an LNG storage tank to a high pressure engine and a low pressure engine, respectively, a pump formed on the fuel supplying line, and configured to pressurize LNG outputted from the LNG storage tank to high pressure, a first heat exchanger formed on the fuel supplying line between the high pressure engine and the pump, and configured to heat the LNG supplied from the pump, a second heat exchanger formed on the fuel supplying line between the low pressure engine and the LNG storage tank, and configured to evaporate the LNG in a liquid state supplied from the LNG storage tank and a heat source supplying line configured to supply heat to the LNG by supplying glycol water to the first heat exchanger and the second heat exchanger. | 09-11-2014 |
