富氢甲烷的爆燃特性与爆炸抑制研究进展
Research progress on the deflagration characteristics and explosion suppression of hydrogen-rich methane
摘要
Abstract
Hydrogen energy is an important component of the future national energy system. Mixing hydrogen with natural gas to form hydrogen-enriched fuel can provide support for the transition of energy structure towards renewable and green energy. However,it also brings more severe safety challenges. To systematically understand the current application status of enriched hydrogen methane fuel and its safe utilization,literature research was conducted to review and discuss the combustion characteristics and explosion suppression research of enriched hydrogen methane from several aspects,including propagation characteristics of deflagration flames,explosion characteristic parameters,deflagration mechanism,and explosion suppression materials. The research direction in recent years was also analyzed and summarized. The results show that as the hydrogen addition ratio increases,parameters such as inherent flame instability,flame propagation speed,and explosion intensity are all enhanced to varying degrees while the explosion suppression effect of suppressants continues to weaken. Currently,there is a lack of research on the explosion characteristics of enriched hydrogen methane under the coupling of multiple factors,and the co-suppression mechanism of explosion suppressants has not been clearly revealed. Based on this,urgent directions and future research focus for the safe development of enriched hydrogen methane fuel are proposed,which can provide a theoretical basis for the large-scale development of the enriched hydrogen natural gas industry.关键词
