Experiment Study on Interchangeability of Multi-Source Natural Gas for Domestic Appliance
With the growing importation of liquefied natural gas (LNG), the interchangeabilities issues of pipeline natural gas (PNG) and LNG are becoming increasingly serious in China. In this paper, some sampled domestic appliances were selected to experimentally investigate the interchangeability of multi-source natural gases including PNG and LNG in Guangdong province. Performances including heat Load, thermal efficiency, CO emission and NOx emission were examined. Through the testing result it can conclude that the heat load of domestic appliances changes consistently with Wobbe Index of gases; well-adjusted domestic appliances can interchange within the different source gases and without materially increasing in CO and NOx emissions, but the efficiency of gas appliance will be largely affected.
