燃气-蒸汽联合循环热效率的估算方法研究摘要:以燃气-蒸汽联合循环系统为基础,根据黑箱子原理和热力学能量平衡定律考虑系统进入的总能与输出的总能,建立分析模型,给出燃气-蒸汽循环系统各设备的能量平衡和热效率的估算方法,并与精确计算相比较,得出估算方法是可行的｡关键词:燃气-蒸汽联合循环;热效率;估算Efficiency Estimation Method of Gas-steam Combined Cycle Thermal Efficiency Abstract: With gas and steam combined cycle system as the foundation, according to the black box principle and thermodynamic energy balance principle, a analysis model was built and a estimation method involved in energy balance and thermal efficiency of gas and steam combined cycle system unit was given in the paper. Compared with precise calculation, the estimation method is feasible.Key words: gas and steam combined cycle; thermal efficiency; estimation燃气-蒸汽联合循环是目前世界上供电效率最高的发电方式之一,其最高的供电效率已接近60%,较之传统的蒸汽发电方式供电效率提高近20个百分点[1,2]｡燃气-蒸汽联合循环是将天然气(包括焦炉煤气和高炉煤气)在燃气轮机的燃烧室中进行燃烧,产生的高温烟气在燃气透平中做功,燃气轮机排气的热量进入余热锅炉加热水产生蒸汽,然后蒸汽在蒸汽轮机做功｡整体循环系统利用了烟气和蒸汽两种工质,将勃莱敦循环和朗肯循环联系在一起,提高了整个系统的热效率｡燃气-蒸汽联合循环系统主要是由压气机､燃气轮机､余热锅炉､蒸汽轮机等设备组成[3,4],其结构示意图如图1所示｡对采用燃气-蒸汽联合循环发电电厂的能量的平衡计算和热效率的精确计算是十分困难的｡但是在实际工程中又需要了解联合循环系统中能量被转化和利用的份额,以便可以找到提高循环热效率的有效途径,这就需要一种估算循环热效率的方法｡研究以整体循环系统为基础,把整个循环系统作为一个黑匣子[5,6],根据热力学能量平衡定律考虑能量进入的总能与能量输出的总能,建立分析模型,给出燃气-蒸汽循环系统的能量平衡和热效率的估算方法｡1分析模型的建立以进入燃烧室的天然气为基准,建立模型计算循环热效率｡将系统进行简化,简化后的系统如下:能量在燃气轮机中只有做功和进入余热锅炉;余热锅炉内能量部分产生蒸汽,其余全部以烟气排向大气;进入蒸汽轮机的能量只有做功与经冷凝器损失到环境中去;并且忽略设备间能量传递的损失｡整个系统中输入的能量只有燃烧的天然气所含有的能量以及这些天然气完全燃烧所需要的空气携带的能量,输出的能量为余热锅炉中排烟携带的能量､经冷凝器损失的能量和做功输出的能量｡分析模型如图2所示｡设进入燃烧室的天然气含有的能量为Q入,天然气完全燃烧所需空气所携带的能量为Qa,燃气轮机的循环效率为ηgt,余热锅炉的效率为ηh,蒸汽轮机的效率为ηst,则能量在各设备中的分布如下｡在燃烧室中的能量分布为:Q入×ηr+Qa=Qs (1)式中Qs为进入燃气轮机的总能量;ηr为燃烧室的效率｡在燃气轮机中的能量分布为:(Q入×ηr+Qa)×ηgt+Qh=Qs(2)式中Qh为进入余热锅炉的能量｡在余热锅炉中的能量分布为:Qh=Qh×ηh+Q烟(3)式中Q烟为在余热锅炉中经烟气排向环境的能量｡在蒸汽轮机中的能量分布为:Q1=Q1×ηst+Q冷(4)式中Q1为进入蒸汽轮机中的能量;Q冷为蒸汽轮机中经冷凝器冷却所损失的能量｡在循环系统中输入的总能量为Q入+Qa,输出的能量只有余热锅炉排烟而损失的热量Q烟,蒸汽轮机经冷凝器损失的热量Q冷､燃气轮机和蒸汽轮机产生的电能(Q入+Qa)×ηgt+Q1ηst｡则该循环系统中损失的能量之和为Q冷+Q烟,利用的能量之和为(Q入+Qa)×ηgt+Q1ηst,循环的热效率为:ηcc= (5)2实例计算与分析有某一燃气-蒸汽联合循环系统,环境温度为30℃,其各设备的利用效率:燃气轮机燃烧室的效率为ηr1=0.98,燃气轮机的循环效率为ηgt=0.37,余热锅炉的热效率为ηh=0.75,蒸汽轮机的循环效率为ηst=0.33,燃料为四川纳溪天然气,其组成成分如表1｡则天然气完全燃烧所需的空气量为:VK=0.5H2*+0.5CO*+2CH4*+1.5H2S*+m+CmHn*(6)式中:H2*,CO*,CH4*,H2S*,CmHn*表示燃料中各种可燃成分的容积百分比｡空气在30℃时的焓值为373.01 kJ/Nm3则总能量Q总=Q入+Qa=3 504.5 kJ+35 588 kJ=39 092.5 kJ｡由公式(1)~(4),可以得出循环系统中各设备中能量利用和损失的情况,如表2所示｡由表2可知,系统做功的热能总量是20 185.39 kJ,损失的总能为18 907.12 kJ,循环的热效率为ηcc=51.63%,其中在循环的热效率中,燃气轮机做功的热效率为36.33%,蒸汽轮机做功的热效率为15.30%,在循环效率中燃气轮机与蒸汽轮机作功之比约为2∶1｡在能量的损失分布中燃烧室损失的热效率为1.82%;余热锅炉损失的热能为15.46%;蒸汽轮机损失的热能为29.43%｡在燃气-蒸汽循环系统的设备中能量的损失大小依次为蒸汽轮机､余热锅炉､燃烧室､燃气轮机｡在联合循环中燃气轮机的热效率高于蒸汽轮机,所以提高燃气轮机ηgt的作用将比同样程度的提高蒸汽轮机的ηst对于改善循环效率ηcc的效果更明显｡而提高燃气轮机燃烧室出口温度(亦即燃气轮机进气温度)T3､降低大气环境温度。

关键词：洁净煤技术联合循环发电煤气化燃烧室磨蚀试验1. 引言“煤的洁净燃烧”技术是当前各工业发达国家都十分重视的研究领域，燃煤燃气－蒸汽联合循环由于能较大幅度提高火力发电厂的热效率，并使污染问题获得解决，因而成为最有发展前途的发电技术。

我国是以燃煤为主的国家，电力工业中燃煤发电厂的装机容量占总装机容量的70%以上。

同时，燃煤发电厂又是严重的污染源，全国SO2总排放量的三分之一，NO X和粉尘总排放量的一半由燃煤发电厂产生。

所以我国对“洁净煤技术”也十分重视，七十年代末国家科委就开始部署“煤的洁净燃烧”发电技术的研究工作。

上海发电设备成套设计研究所在“六五”到“八五”期间先后承担了国家科委下达的燃煤燃气－蒸汽联合循环项目中的“低热值煤气燃气轮机关键技术研究”、“常压流化床空气埋管传热试验研究”、“第二代增压流化床联合循环发电关键技术研究”等科技攻关课题。

在吸收国外先进技术的基础上，成功地开展了对上述关键技术的攻关，取得了科研成果。

本文将介绍这些科技攻关课题的研究概况。

2. 低热值煤气燃气轮机关键技术研究整体煤气化燃气－蒸汽联合循环（IGCC）是“煤的洁净燃烧”发电技术的一个重要方式。

在IGCC中的燃气轮机必须可靠地燃烧气化炉产生的中、低热值煤气，标准的燃气轮机产品必须经过对燃烧系统改造方能满足IGCC的要求。

1981年国家科委布置了燃煤联合循环发电的关键技术科研攻关工作，上海发电设备成套设计研究所承担了“燃用低热值煤气的燃气轮机技术研究”课题，研究内容包括“低热值煤气燃气轮机燃烧室试验研究”和“低热值煤气燃气轮机燃料调节系统试验研究”两个方面。

课题攻关于1990年10月完成，并通过了国家科委和机械工业部组织的专家鉴定，主要研究成果有：2.1建立了国内第一套使用配制组合压缩气体为燃料的气体燃料燃烧室试验台，可进行燃气轮机燃烧室燃油、燃气或油气混燃的低压模化试验，配置了供油、供气体燃料的燃料系统、空气供应系统及燃烧室试验控制系统。
