摘　　要：This manuscript developed an adjustability test system of gas appliances,and proposed determination methods of adjustability domain and technical approach of performance testing of gas appliance,in order to develop experimental determination,quantify the product performance,design quality and combustion characteristics of gas appliances,and provide test foundation and platform for product design,performance test,quality assessment and technology upgrading for gas appliance industry aiming to multi-gas resources in China.The flexible range of gas appliances to different gases and the interchangeability domain of city gases were determined experimentally,together with the equation of combustion characteristics limit curves of gas appliances.The results showed that the second gas appliance has the biggest capability for the change of gas quality,which permits an 11.2% fluctuation in the Wobbe Index of gas;while the third gas appliance has the least capability for the change of gas quality,which only permits a 1.9% fluctuation in the Wobbe Index of gas.The paper also provides the common adjustability domain of the three gas appliances.This manuscript developed an adjustability test system of gas appliances, and proposed determination methods of adjustability domain and technical approach of performance testing of gas appliance, in order to develop experimental determination, quantify the product performance, design quality and combustion characteristics of gas appliances, and provide test foundation and platform for product design, performance test, quality assessment and technology upgrading for gas appliance industry aiming to multi-gas resources in China.
