燃用超低热值燃料的燃气轮机及其热力分析 翁一武。尹娟 (上海交通大学机械与动力工程学院，上海) 摘要：超低热值燃料中燃料总热值很低，仅为天然气热值的百分之几，通常情况下不能点火 燃烧，目前绝大部分都直接排放，造成巨大能源浪费的同时也加剧了温室效应。提出一种燃用超低 热值燃料的方法，介绍其组成及原理并分析技术关键点，并利用实验验证超低热值燃料稳定催化燃 烧的可行性。论文还将以百千瓦级功率为例进行热力循环计算和分析，为燃用超低热值燃料燃气 轮机系统的研制提供切实可行的方法和依据，也为超低热值燃料的回收利用提供一种行之有效的 途径。 关键词：超低热值燃料；催化燃烧；燃气轮机特性；热力循环 CharacteristicsandThermalCricle on HeatValueFuelGasTurbine AnalysisSuper-Low WENGYi-wu，YINJuan (Mechanical＆Power EngineeringInstitute。ShanghaiJiaotongUniversity，Commonwealth MallettC Shi) ScienceandIndustryResearch W，SU Organization。Australia natural containedin small ofmethaneis asseveral asnormal Abstract：Aquantity usuallyonly percent gas，is heat couldn’tbe innormal aresultofits super-lowvaluefueL heatvaluefuel condition，as large Super-low ignited amountand exhaustedintoair iswastedand effectisincreased being directly，energybadlygreenhouse seriously． This a of turbinethatcouldutilize heatvaluefuel，besides advancedkind combustion paper catalytic gas super-low introducedits and its the configurationoperatingprinciple，analyzedkeytechnology，andexperimentalizedfeasibility ofthe with heatvalue an ofthe turbinewith of catalyticcombustion fuel．Asexample gas grade super-low of ofthermal it
