摘　　要：针对国内外燃料重整在燃烧系统余热回收中的应用现状,归纳总结了重整反应机理,余热回收系统及重整器结构设计的研究进展。现有研究表明,不同重整反应类型因其总焓变及产物差异在重整系统中表现为不同反应温度及积碳特性。针对内燃机、燃气轮机、燃烧锅炉3种燃烧系统的燃料重整研究显示重整反应有助于提高系统热效率,控制污染排放。在重整器设计方面,采用先混合后换热的设计方案有利于提高燃料混合均匀性,但易导致反应器积碳,而采用先换热后混合的设计方案则反之。选用贵金属催化剂可显著抑制反应器积碳。Basing on the state of art for the application of reforming technology on waste heat recovery,progress in reforming mechanisms,heat recovery systems,and the designs of fuel reformer is reviewed.From previous works,different reforming methods show the varied reaction temperatures and carbon deposition characteristics due to the deviation in their total enthalpy change and the products.Fuel reforming studies on internal combustion engine,gas turbine,and combustion boiler indicate that fuel reforming contributes to thermal efficiency improvement and emissions reduction.The reformer design with mixing followed by heat exchange is beneficial for mixture uniformity improvement,but this tends to cause coking in the reactor,and vice versa.Noble metal catalysts can significantly suppress the carbon deposition in the reactor.
