Performance and Emission Characteristics of GHP Engine at Different Natural Gas Heating Value

Abstract

In general, natural gas is used as GHP(Gas Engine Driven Heat Pump) fuel. On this study, the influences of different natural gas heating value on GHP were evaluated. As a result of engine test & field test using low heating value gas(9,800 kcal/Nm 3 ) as fuel, the engine power was reduced slightly, however the performance of start-up, the stability of operation and the characteristics of emission gas were almost similar. So it is considered that the normal operation of GHP is possible without any tuning when the low heating value(9,800 kcal/Nm 3 ) of natural gas was used as fuel.
