FUEL GAS SYSTEM WHICH CONTROLS TO BE AN OPTIMAL TEMPERATURE FOR THE SUPPLY OF LIQUIDS TRANSFERRED FROM A WASHER TO A SEPARATOR AND WHICH PRODUCES FUEL GAS FROM NATURAL GAS

摘要

PURPOSE: A fuel gas system is provided to reduce the loads on a level control valve by allowing only liquid to be transferred into the level control valve by preventing the influx of gas contained in the liquid into the level control valve, and to extend the lifespan of the level control valve and a pipe by preventing vibration and noise caused by the influx of gas.;CONSTITUTION: A fuel gas system comprises a fuel washer(1), a thermal exchanger(2), a level control valve(4), a gas-liquid separation pipe(10), and a bypass pipe(11). The fuel washer refines condensation contained in fuel gas. The thermal exchanger controls the temperature of discharged liquid from the washer to supply the liquid into a separator(3). The level control valve is installed on a supply pipe between the thermal exchanger and the separator, and controls the level of the liquid through the delivery rate control of the supply pipe. The gas-liquid separation pipe is installed between a discharge port of the thermal exchanger and an input port of the level control valve, and separates the discharged liquid from the discharge port into liquid and gas. The gas bypass pipe supplies the gas separated from the gas-liquid separation pipe into the separator by avoiding the level control valve.;COPYRIGHT KIPO 2013;[Reference numerals] (3) Separator
