燃气采暖热水炉在纯甲烷和上海地区
天然气条件的性能测试比较口同济大学机械与能源工程学院（201804）周宇秦朝葵
摘要：标准规定燃用天然气的采暖热水炉测试时需采用基准气纯甲烷，目的是为了统一比较基
准，而通过多次的色谱分析可知，上海地区管道天然气的成分较为稳定，低热值和华白数均没有明显变化，此外，和天然气相比，甲烷价格昂责，且不易获得，固此本文根据国家标准GB25034-1010《燃气采暖热水炉》搭建试验台，分别对纯甲烷和上海地区天然气下燃气采暖热水炉的排放和效率进行了测试和比较。结果表明：燃用天然气时的热效率均使用比纯甲烷时高，部分负荷下更为明显，而CO和NOx等污染物排放的差异并不明显，可以考虑使用燃用上海地区天然气条件下采暖热水炉的性能测试结果近似评估燃气采暖热水炉的性能。

Abstract:In order to unify the benchmark, standard stipulates that the pure methane should be used
while testing a gas-fired heating and hot water combi-boiler, however, more than once chromatographic analysis indicate that the component of natural gas in Shanghai is very stable, and the low heating value and wobbe index are not significantly change, what's more, compared with natural gas, pure methane is more expensive and uneasily-get. In this paper, an experimental bench was built according to the GB 25034-1010 《Gas-fired heating and hot water combi-boilers》 , then the emissions and thermal eficiency of Gas-fired heating and hot water combi-boilers under pure methane and natural gas in Shanghai were tested respectively Results show that the thermal efficiency is higher while burning natural gas, especially under partial load; but the difference of CO and NOx emissions are not that obvious, so the results of gas-fired heating and hot water combi-boiler under natural gas can be used to evaluate the performance of boiler approximately in Shanghai area
