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
Study on the effect of natural gas blending with hydrogen-containing industrial tail gas on the combustion characteristics of in-service household gas cooktops
摘要
Abstract
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.关键词
