This thesis summarize the experience of designing , primary running , testing and acceptance of beijing 3 thermal power plant , submit questions that we should pay attention to for the gas - steam combined cycle project in our designing work in the future 对工程设计、试运行和验收工作进行了总结，提出了在今后设计大型联合循环电站时应注意的问题，阐述在此工程实施中体会。
Repowering the old power plant by gas turbine combined cycle ( gtcc ) , which can enhance the using efficiency of energy , reduce the consumption of energy , save investment because of using the existed equipments and take effect rapidly 利用燃气-蒸汽联合循环对老电厂进行改造，能够提高能源的综合使用率，降低能耗，并有效利用老电厂的现有设备，可以减少投资并且见效快。
In order to develop combined cycle generation technology answering for the situation of our country , institute for thermal power engineering in zhejiang university has designed and built a mulit - product cogeneration test using combined coal gasification and combustion 为了发展符合我国国情的联合循环发电技术，浙江大学热能工程研究所设计和建造了煤燃烧气化多联产试验台。
The combined cycle power generation burning natural gas and coal - based gas has become a practical power generation technology which is more and more popular world - wide for its both advantages of cleanness ( energy ) and high efficiency ( method of power generation ) 以天然气、煤层气为燃料的联合循环? ? “燃气联合循环”发电集清洁(能源) 、高效(发电方式)于一身，成为当今世界愈加受到青睐的实用发电技术。
Two kinds of representative cc - repowering ( feed water heating repowering , full firing repowering ) are study in this paper . the concise performance expressions and typical data are analyzed for the combined cycle and for repowering the existed steam power station 本文针对两种典型的联合循环系统（排气助燃型和给水加热型）进行了研究，给出了这两种联合循环及其在用以增容改造已有的蒸汽轮机电厂时的性能简明示式和典型数据。
Main products of nanjing turbine & electric machinery ( group ) co . , ltd are heavy - duty gas turbine generating unit , steam turbine generating unit , gas - steam combined cycle unit , co - gen . steam turbine unit and generator as well as large & medium sized synchronized / asynchronized motors 南京汽轮电机（集团）有限责任公司主产品有重型燃气轮发电机组及燃气/蒸汽联合循环发电设备、热电联供汽轮发电机组和大中型同步、异步交流电动机。
This paper gives an example that is a project about repowering 2 50mw coal - fired plant as combined cycle . it is found out that after full firing repowering , the absolute efficiency gain is 4 . 62 % and after feed water heating repowering , the absolute efficiency gain is 2 . 78 % 本文结合2 50mw燃煤机组改造为联合循环的方案实例，计算出排气助燃型联合循环系统更新改造使原燃煤机组绝对效率提高了4 . 62 % ，给水加热型联合循环系统更新改造使原燃煤机组绝对效率提高了2 . 78 % 。
After a brief introduction of the utilization of combined cycle generation technology , a review of types , current research and development of combined cycle generation technology were given first . the development , technical features , projects and research organizations of igcc and pfbc - cc are mainly introduced . at the same time , coal combustion combined cycle technologies and the program , features and current research of steam - electric - gas in china are also introduced 在对联合循环发电的技术及利用意义简要介绍的基础上，本文首先对联合循环发电技术的类型及其研究发展现状进行了综述，主要针对整体煤气化联合循环、增压流化床联合循环的系统的发展、技术特点以及示范工程等基本情况进行了介绍；同时对我国的燃煤联合循环发电技术及热电气“三联产”技术的工艺流程、特点及研究现状进行了介绍。
