天然气掺混含氢工业尾气对在役家用燃气灶具燃烧特性影响研究OA
Study on the effect of natural gas blending with hydrogen-containing industrial tail gas on the combustion characteristics of in-service household gas cooktops
城镇燃气管网掺氢是目前氢能利用的重点研究领域,具有极大发展前景.为研究天然气掺混含氢工业尾气对在役家用燃气灶具燃烧特性的影响,文章通过燃气互换性理论确定了含氢工业尾气的最大掺混比例为39％(氢气含量为 18％).在此基础上设置灶前压力分别为 1 500,2 000,3 000 Pa,并控制掺混气中氢气含量分别为0％,5％,10％,15％,18％,对在役燃气灶具和新灶具进行燃烧特性测试.结果表明:在天然气中掺混39％含氢工业尾气后,燃气灶具的点火成功率和火焰稳定性合格率均为 100％,无安全性问题;部分在役灶具在燃烧掺混气后,烟气中 CO 含量由不合格降至合格,在役灶具烟气中 CO 含量合格率提高了 20％以上;随掺混气中氢气含量的增加,燃气灶具烟气中 NOx 含量呈波动状态,未见明显变化趋势;天然气中掺混 39％含氢工业尾气(氢气含量为 18％)不会影响在役家用燃气灶具的正常、安全使用.
Hydrogen blending in urban gas distribution networks is currently a key research area in hydrogen energy utilization and holds tremendous potential for future development.To investigate the effect of blending natural gas with hydrogen-containing industrial tail gas on the combustion characteristics of in-service household gas cooktops,this paper first determined,based on gas interchangeability theory,that the maximum blending ratio of the tail gas is 39％(with a hydrogen content of 18％).On this basis,combustion tests were conducted on both retrieved in-service cooktops and newly purchased cooktops,with the inlet pressure set at 1 500,2 000,3 000 Pa,respectively,and the hydrogen content in the blended gas controlled at 0％,5％,10％,15％,and 18％.The results show that the ignition success rate and flame stability pass rate were both 100％for all tested cooktops,with no safety issues observed.For certain in-service cooktops,the CO concentration in flue gas dropped from non-compliant to compliant levels after combustion of the blended gas,and the CO content pass rate across all categories of in-service cooktops increased by more than 20％.As the hydrogen content in the blended gas increased,the NOx from the tested cooktops fluctuated without showing a clear trend.Overall,blending 39％of this tail gas(with 18％hydrogen)into natural gas does not impair the normal and safe operation of in-service household gas cooktops.
