摘要：不同气源的天然气接入同一管网系统，改善供应可靠性的同时，带来燃烧特性差别的问
题。家用灶具数量虎大，当天然气组分变化时，CO、NOx等污染物排放量若出现超标情况，因不会像离始、吹熄一样可肉眼发现，将构成潜在的长期危害且造成环境污染。为研究气源组分变化而灶具不进行任何调整的情况下灶具的排放，作者选取17台样本燃气灶（其中16台为嵌入式灶，1台为台式灶），测试了10种不同组分的天然气及12T-0下的 CO、NOx排放，发现同一灶具在不同组分天然气下CO排放差别较大，并指出：实验研究天然气组分变化导致的污染物排放问题是互换性研究的重点之一且对促进天然气的高效与安全使用、规范气质管理具有重要意义。

School of mechanical engineering,TONGJI UniversityQin Chaokui, Chen Nannan Abstract:With natural gases from different sources being introduced into the same network, supply
security would be improved while difference in combustion characteristics shows up. If CO/ NOx emissions from huge amounts of domestic gas cookers increase as a result of variable gas constituents, long-term hazard and environmental pollution may be resulted in since it is quite difficult to observe by naked eyes as with lift or blow-out. To investigate the CO/NOx emissions of domestic gas cookers without any adjustment under variable gas constituents, 1o kinds of natural gases were input into 17 sets of sample gas cookers (16 sets of embedded type and 1 set of desktop type)to evaluate CO/NOx emissions.The results show that CO/NOx emissions from the same gas cooker fueled with different gases vary dramatically. It was concluded that pollutant emissions resulting from changing gas constituents should be an important part of gas interchangeability research. The research in this field would be helpful to safe and efficient utilization ofgas and can promote gas quality management as well.
