摘　　要：使用管道天然气掺混乙烷、氮气的方法模拟LNG,并配制不同比例管道天然气与LNG的掺混气,对上海市场上几种热水器的热工性能进行响应测试。测试结果表明:随LNG比例的增加,热水器负荷增加,热效率下降,CO排放基本处于国标允许的范围内,NOX排放无显著变化。热效率的变化会引起能效指标管理方面的混乱,需引起重视。Pipeline natural gas （ PNG ） in lab was blended with ethane and nitrogen to simulate liquefied natural gas （ LNG ） . The mixed gases of LNG and PNG at different proportions were used to test performance response of several water heaters popular in Shanghai markets. The result shows that when the percentage of LNG increased from 0% to 100%, the heat load of water heater increased, the thermal efficiency decreased, the CO emission is basically less than 500ppm, which comply with the national standard, and no significant change was observed in NOx emission. Serious attention should be paid to thermal efficiency changes, close related to Energy Efficiency Administration.
