Article Excerpt
First firing of the 340 MW SGT5-8000H is scheduled for this winter, the culmination of a development effort that started about seven years ago.

Customer demand and market requirements were the essential drivers for the development of the new machine, says Siemens, which aims to fulfil the following requirements:

* combined cycle net efficiency of over 60%;

* fast start capability and high operational flexibility;

* lowest life cycle costs;

* high reliability and availability;

* low emissions; and

* good turn down capability while still maintaining high efficiency and low emissions.

Siemens Power Generation started its internal product development process in 2000 with strategic product planning activities. In 2005 the company announced it was developing the world's most powerful gas turbine. Two years later, and on schedule, the prototype of the SGT5-8000H was shipped to its destination, the Irsching 4 gas turbine power plant.

With the acquisition of the Alstom industrial turbine business the Siemens range goes down to 5 MWe, while the new H raises the upper limit from 287 MW (the SGT5-4000F) to the aforementioned 340 MW.

The H is the result of an intensive research & development programme aimed at developing a competitive, efficient and flexible fully-aircooled engine.

It is the first new frame developed since the merger of Siemens and Westinghouse, and aims to combine the best features of both companies' existing product lines with advanced technology. Proven design features have been applied wherever possible and use has also been made of Six Sigma processes.

The new machine has been developed by a 250 strong team located in a number of locations, in particular Erlangen, Berlin and Mulheim in Germany and Orlando and Jupiter in Florida, USA.

An additional 500 Siemens employees were involved in the manufacturing and preparation of the prototype engine for testing and at present about 800 people are working on the prototype design and erection at Irsching.

Basic data for the new turbine can be summarised as follows:

Fuel Natural. gas, fuel oil Grid frequency 50 Hz GT output 340 MW GT efficiency > 39% GT heat rate

Efficiency leap

Back in 1992, Siemens' Killingholme combined cycle plant achieved an efficiency of 52%. Didcot, with one of the first V94.3A machines (predecessor of the SGT5-4000F), achieved 56% in 1996 and the Mainz-Wiesbaden combined cycle plant, with the latest version of the SGT5-4000F, reached an efficiency world record of more than 58% in 2001. Irsching will break the 60% barrier.

The SGT5-8000H gas turbine will be the prime mover of the new Siemens combined cycle offering for the 50 Hz market, the SCC5-8000H, which will have an output of over 530 MW.

Key features of the new turbine are:

* axial 13 stage compressor with high mass flow, high component efficiency, CDA front stages and HPA rear stages, variable guide vanes, cantilevered stator vanes;

* high temperature can annular combustion system, air-cooled;

* four stage turbine with stage 1 single crystal blades and vanes, stage 1 to 3 TBC coated blades and vanes, air-cooled;

* advanced, variable secondary air system (SAS);

* single tie bolt rotor with compressor and turbine disks and hydraulic clearance optimisation (HCO); and

* direct scaling for further frames, eg for a 60 Hz machine.

Features contributing to higher efficiency include:

* advanced sealing system for low leakage of cooling air;

* advanced materials to increase the firing and exhaust gas temperatures;

* new compressor with advanced blade design;

* advanced, highly efficient, high pressure and high temperature combined cycle process employing the Benson boiler; and

* proven single shaft concept with SSS clutch operating with an advanced, high temperature steam turbine.

Features expected to contribute to low life cycle costs include:

* the high, ie over 60%, efficiency in combined cycle mode;

* low maintenance and operation costs due to less complexity in engine and parts; and

* simple operational concept;

Features that aim to increase operating flexibility include:

* 100 per cent air-cooling, which means that the cooling system is always operational, whatever the speed and load (even in open cycle operation); and

* flexibility in operation, reduced start-up times and high ramp rates due to reduced complexity in the engine and plant.

Siemens has not yet disclosed the firing temperature of the new turbine, but Phil Ratliff of Siemens said recently: "I'll describe it as a 1600 degree C machine, only slightly hotter than the 501G."

Minimising risks

The product development process consists of several review steps and five release gates taken up by senior management and in some cases even up to the board level. In total, about 550 design reviews have been performed on components, systems and the total cycle, and more than 60 man years in total invested in additional quality steps and activities such as QFD (quality function deployment and Six Sigma.

To minimise risks during the introduction of the new machine, complete component prototype tests have been carried out, with all key gas turbine components pre-validated in subsystem...

最新消息，完成试运行

Siemens Energy Completes Trial Operation Of SGT5-8000H Gas TurbinePublished: 24-Sep-2009

Siemens Energy has completed trial operation of the SGT5-8000H gas turbine in the Irsching 4 power plant.
After 1500 operating hours, 1200 at full load, and evaluation of the measured data the machine's original rated output of 340MW was raised to 375MW in simple cycle duty. The company said that in combined cycle operation, output will increase by 40MW to more than als 570MW.

According to the company, these 40MW are sufficient to supply a further 220,000 people with electricity. Meanwhile, expansion of the plant to a combined cycle station has commenced. In 2011, E.ON will take over the fossil-fueled power plant.

Michael Suess, CEO of the Fossil Power Generation Division of Siemens Energy, said: "With its energy efficiency and high performance level the new gas turbine is a prime example of climate protection. Compared to the first advanced combined cycle plants the new gas turbine reduces annual CO2-emissions by approximately 45,000 metric tons."

Bernhard Fischer, member of the managing board of E.ON Energie and E.ON's CTO, said: "In Irsching, Block 4, we were able to experience the performance of the world’s most efficient gas turbine for ourselves.
"Expansion is currently under way to a combined cycle power plant. With its commissioning in the year 2011, it will similarly set new standards when it comes to efficiency and output.”

这么好的资料，我居然今天才看见，下载并顶了。
总的来说西门子的燃气轮机水平似乎比不上GE，西门子也有热效率60%的联合循环机组，多少有点让我意外。
学习之~~~

通用电气能源集团（GE Energy）在位于英国南威尔士的Baglan Bay发电厂安装了其第一套H系统（燃气-蒸汽联合循环机组）。该电厂于2003年投入商业运营，迄今为止已经累计运行了3万多个小时。据通用电气称，目前它的运行功率为480MW，并且还有提升的空间。
通用电气公司还有其他五台H系统机组目前正处在不同的实施阶段：其中三台在日本东电力公司（TEPCO）的富津热电站。这些50赫兹机组中第一台已于2007年12月开始点火，并预计在2008年夏末投入运行。H系统在东电力公司中的第2和第3台机组预定于2010年年中投入运行。
通用电气公司在美国的第一台H级机组，也是第一台60赫兹机组，于2006年在位于加利福尼亚州Riverside郡的天然气联合循环发电厂 Inland Empire Energy Center安装。这个发电厂由两套通用电气H系统构成，其最大的净额定输出电力为775MW，主要面向家庭和商业用户。Inland的这两个机组预计将于今年夏季晚些时候开始入网发电。
与此同时，西门子发电集团（Siemens Power Generation）也正在积极推进其H级SGT5-8000H机组尽快投入商业运营。这款机组被安装在位于德国Ingolstadt附近的 Irsching 4天然气发电厂，并于2007年12月进行了第一次点火。西门子公司的新一代燃气涡轮机总监Phillip Ratliff表示，该机组将于2008年3月进行第一次并网发电，并从2008年4月开始进行满负荷测试（单一循环模式）。
西门子公司的50赫兹机组的输出功率为340MW，但是在最终的联合循环运行环境中其设计功率可以达到530MW，预计效率可以达到60％以上。Ratliff说：“在对第一个设计进行了深入论证之后，目前他们正在开发60赫兹机组。”
对于SGT5-8000H机组的反复测试和论证项目将一直持续到2009年年中。然后，该联合循环发电厂的扩建将在该项目的第2期开始，并将于2011年中期移交给该电厂的运营商，德国E. ON公司。
对于燃气轮机发电领域来说，未来几年的前景十分值得期待。
