氢气燃烧技术及其进展

Hydrogen Combustion Technology and Progress

随着碳减排政策的不断推进,氢气因其高能量密度和低碳排放特性被视为一种理想的能源,并广泛应用于化工原料制备、移动出行、电力生产以及工业和家庭用热等领域,而燃烧是目前氢能利用的重要方式之一。基于此,通过对比氢气与天然气的物理化学特性,详细分析和探讨了氢气燃烧过程中存在的各种类型的回火、热声振荡以及氮氧化物排放超标问题发生的原因和解决方法;而后,概述了氢气催化燃烧和微尺度燃烧在工业脱氢、家庭供热和微机电系统等领域的应用现状和发展方向;最后,结合目前世界各国天然气掺氢燃烧的发展现状和中国天然气管网的相应标准,指出中国发展天然气掺氢燃烧的优势和关键问题,总结了氢气燃烧技术的发展现状与发展趋势。

With the continuous promotion of carbon emission reduction policies,hydrogen is regarded as an ideal energy because of its high energy density and low carbon emission characteristics,and is widely used in chemical raw material preparation,mobile travel,electric power production,industrial and household heating and other fields.Combustion is one of the important ways of hydrogen energy utilization at present.Based on this,by comparing the physical and chemical characteristics of hydrogen and natural gas,the causes and solutions of various types of tempering,thermoacoustic oscillation and NOxemission exceeding standards in hydrogen combustion were analyzed and discussed in detail.Then,the application status and development direction of hydrogen catalytic combustion and micro-scale combustion in industrial dehydrogenation,home heating and micro-electro-mechanical system were summarized.Finally,the advantages and key problems of the development of natural gas hydrogen-doped combustion in China were pointed out based on the current development status of natural gas hydrogen-doped combustion in the world and the corresponding standards of natural gas pipe network in China,and the development status and trend of hydrogen combustion technology were summarized.
