| 摘要 |
The present invention relates to a fuel gas supply system and a method for supplying fuel gas and, more specifically, a fuel gas supply system and a method for supplying fuel gas. The fuel gas supply system compresses evaporation gas generated in a liquefied natural gas storage tank using a four stage compressor to be supplied to a DFDE engine. According to the present invention, appropriate fuel gas can be supplied to the DFDE engine by only compressing the evaporation gas supplied from the liquefied natural gas storage tank without an additional cooling process. Therefore, a cooling device and a cooing process conventionally required for cooling the evaporation gas supplied from the liquefied natural gas storage tank can be omitted to simplify the fuel gas supply system and the method for supplying fuel gas. |
