GE重型燃气轮机的性能及参数Frank J.BrooksGE动力系统集团Schenectady,纽约引言GE既可为发电部问及工业用户提供重型燃气轮机,亦可生产和提供航空衍生型即所谓轻型燃气轮机。
重型燃机包括5个不同的型号系列:MS3002,MS5000,MS6001,MS7001及MS9001。
MS5001属容量较小的机组,其按单轴和双轴的布置设计用于机械驱动及发电。
MS6001之类中等容量的机组或更大的机组,则仅为单轴的。
用于发电的燃机,出力范围小至199,997马力(20,000千瓦)大及378,162马力(282,000干瓦)。
GE重型的燃气轮机通用的出力及热耗参数洋见表1。
机械驱动用机组的额定值,在14,520马力到108,200马力门(10,828千瓦到80,685千瓦)之间,如表2之所示。
表1GE燃气轮机的性能参数发电用燃气轮机的额定值G=天然气, D=轻柴油表2机械驱动燃气轮机的额定值在表1和表2中,对于每种重型燃机,标有相应的型号标记。
其含义见图1。
本文将讨论有关燃气轮机运行的一些热力学基本原理,并且对影响其运行性能的一些因素予以解析。
热力学原理图2所示为单轴、简单循环的燃气轮机原理图。
在周围环境条件下,空气于点1处进入轴流式压缩机。
因为这些条件因时因地而异,为了便于比较,特假定一些标准的条件。
燃机业界所采用的假定标准工况况通常为:59°F/15°C,14.7psia/1.013巴及60%的相对湿度,它是国际标准协会(ISO)所规定的,常被表述为ISO条件。
空气在点1处进入压缩机后以恒温被加压至较高压力。
但压缩使空气温度升高。
故由压缩机排出的空气,其温度和压力都将被提高。
空气离开压缩机之后,在点2处进入燃烧系统。
在那里,燃料被喷入并燃烧。
燃烧过程基本处于恒压状态。
虽在一次燃烧内局部达到了高温(接近理想条件),但因燃烧室内所发生的混合、燃烧、稀释及冷却等过程使燃烧混合物在离开燃烧室后于点3处进入透平时,其温度为混合后的平均值。
天然气发电经济性分析和GE9F机组简介天然气发电1985-2000年间天然气在发电领域的消费增长速度为年均2%,增长部分主要集中在发达国家。
发展中国家由于电价承受能力较低和环保标准执行不严,天然气发电还未得到普遍采用,但随着天然气燃气——蒸汽联合循环发电装置单机容量的不断扩大,热效率不断提高,以及优越的环保效益,天然气发电今后在发展中国家将有广阔的发展前景。
即使在资源缺乏的地区,也在积极研究进口LNG,如我国东南沿海地区的上海,福建,广东等。
进口LNG主要用于发电。
天然气发电与其他火力发电相比,具有明显的特点:1 .对环境的污染小天然气由于经过了净化处理,含硫量极低,每亿千瓦时电排放的SO2为2吨,仅是普通燃煤电厂的千分之一。
另外耗水少,只有煤发电厂的1/3,因而废水排放量减少到最低程度。
至于灰渣,排放量为零,远远优于煤电。
2 .热效率高普通燃煤蒸汽电厂热效率的高限为40%,而天然气燃气——蒸汽联合循环电厂的热效率目前已达到56%,且还在提高。
这主要是联合循环将燃气透平与蒸汽透平进行了有机结合,从而提高了燃料蕴储的化学能与机械功之间的转换效率。
以GE公司的三压再热式GE9F 燃气——蒸汽联合循环机组为例,燃气透平机的热利用率为%,余热蒸汽透平机的热利用率为%,减去机组自身%的热损失,GE9F联合循环发电机的总热效率为%.3 .占地小,定员少燃气——蒸汽联合循环电厂占地小,以2500MW 电厂为例,燃气——蒸汽联合循环电厂占地12hm2,而燃煤电厂却高达52hm2,是前者的4倍多,由于联合循环电厂布置紧凑,自动化程度高,定员仅为300人。
4 .投资省由于单机容量大型化,辅助设备少,联合循环电厂的投资不断下降。
据Shell公司称,国外联合循环电厂每千瓦投资已降到400美元左右,而燃煤带脱硫装置的电厂每千瓦投资为800——850美元,高出一倍以上。
5. 调峰性好燃气——蒸汽联合循环电厂开停车方便,调峰性好,从启动到带满负荷仅需1H左右。

TECHNOLOGY WINDGE 公司F 级燃机汽轮机是一代具有良好的性能的发电机组,于20世纪80年代被研发出来,这也是GE 公司通过长期的发展计划所获得的成果。
在1981年,GE 公司就已经开始对F 级燃机汽轮机进行实施计划,运用燃烧温度比较高的大型的燃机汽轮机,不仅能使联合循环电厂的工作效率得到提高,而且还能大大减少发电厂运营成本。
F 级燃机汽轮机,GE 公司研究中心与GE 的航空发电机公司共同研发的科技结晶,对新一代科技的产生与应用起到了促进作用。
1F 级燃机汽轮机产品及性能的演变F 级燃机汽轮机型号的多样性,能够满足不同使用者的需求,其中,MS9000、MS7000以及MS9000的燃机系列中,都生产有F 级产品,而且运行性能良好(见表一)。
MS6001FA 、MS7001FA 及MS9001FA 的燃机汽轮机均设有3级燃气透平和18级压气机,它们都是以轴向排气和冷端驱动为主要特征,对联合循环的布置非常有利。
F 级的燃机汽轮机采用的是GE 公司分管式的燃烧系统,并具有传统性和可靠性,而且F 级燃机还可配置有双燃料的燃烧系统,例如,如果主燃料为天然气,那么轻油就是其辅助燃料。
在主燃料天然气发生意外故障时,轮机组就会自动的把主燃料变换成轻油,以确保燃机不会因为燃料供应出现故障而终止运转,这样就更加保证了机器运转的可用性和可靠性。
同时机组也可以根据实际情况使用双燃料方式进行混合燃烧。
除此之外,F 级的燃机汽轮机也能够使用低热量的燃料,这样就在很大程度上扩大了燃料供应的范围及灵活性。
而且F 级燃机汽轮机由IGCC 电厂提供能源,这也在燃煤过程中,最大程度上降低了对自然环境的影响。
2压气机GE 公司的F 级燃机汽轮机中所使用的压气机,运用E 型燃机汽轮机的17级压气机,用空气动力学进行模化的原理设计,同时又加大了1个零级,即:增加到18级。
压缩比率大约为15。
为了避免在机器启动时出现压气机喘振的现象,在压气机内都会装有1~2个中间级别的出气口和进口转导叶,F 级机组放气口一般置于第9和13级之后,联合循环方式在运行的过程中,进口可以转为导叶,而且还能在一定的承载范围内保证在透平之前燃气的温度不会改变。

航空史秘闻—GE的航空发动机是怎样诞生的?想必很多人都知道第一盏具有实用功能的灯泡是GE创始人爱迪生发明的。
其实,这位“发明大王”涉猎非常广泛!由他亲手缔造的GE 公司,其业务也从早年的电力设备,拓展至磁共振设备和燃气轮机等多个领域,成为了名副其实的工业巨头。
其实,看似不相关的GE各个业务,可能相互之间存在着千丝万缕的联系。
比如,在照明领域的积累让GE将业务拓展至X光机和医学影像领域;GE在发电和燃气轮机方面强劲的实力,孕育了公司的航空业务。
而时至今日,GE航空的工程师又会依靠航空发动机领域的专业知识与经验帮助发电集团的同事制造出更高效的燃气轮机。
这就是“GE商店”——全球知识交换系统的力量,充分发挥协同效应,实现1+1 >2的威力!今天要和大家聊的,就是GE航空与GE发电“相亲相爱”的那些事。
随着电气化时代的来临,人类对电力的需求开始迅猛增加。
最初的发电设备都是活塞式汽油发电机。
但是很快,人们发现蒸汽轮机是一种更高效的发电设备,纷纷转向这一领域。
1903年,也就是莱特兄弟发明飞机的那一年,GE制造出了当时世界上出力最大的汽轮发电机组(见上图),它具有占地面积小、成本低等优点,被安装在了美国罗德岛州的纽波特电厂。
而后来的GE航空业务的创立,就得益于公司在发电领域的人才与技术积累。
这座电厂,也称得上是孕育了GE的航空业务。
同年,年轻的工程师莫斯(Sanford Moss)加入GE的汽轮发电机事业部。
这位康奈尔大学博士毕业的高材生在这里进行了革命性的研发工作:利用离心式压缩机在空气进入涡轮前对其进行压缩。
虽然他的试验经历了诸多失败,但是其最终成果点亮了一盏通向喷气式发动机之路的明灯。
1917年11月,NASA的前身——美国国家航空咨询委员会找到GE,希望莫斯的发明能够帮助他们提升“Liberty”航空发动机的动力水平。
这款在海平面时功率可达354马力的发动机,在飞行高度增加时,输出功率会明显下降。
