摘　　要：《家用燃气快速热水器》(GB 6932-2015)标准规定,烟气中CO含量的测定,可以使用干式或湿式流量计。城镇燃气为干燃气,经过湿式流量计的燃气相对湿度接近100%。根据GB 6932-2015规定的试验方法进行研究,结果表明:在其他条件不变的情况下,干燃气燃烧产生的CO值高于湿燃气产生的CO值,燃气热水器燃烧时产生的CO_(2)是在火焰内部完成,采用干燃气测量CO含量更为适宜。In the test specified in GB 6932—2015, both dry gas-meter and wet gas-meter can be used. At the same time,the urban gas is dry gas, and the relative humidity of the gas passing through the wet gas-meter is close to 100%. In this paper, the test method specified in GB 6932—2015 was used for research. The results show that the CO value produced by dry gas combustion is higher than that produced by wet gas combustion, then combined with the gas chain reaction mechanism and the structural characteristics of the water heater, the CO2 produced during the combustion of the gas water heater is completed in the flame, and the dry gas is a more stringent test method to measure the CO concentration.
