Selection and application of performance test standards for large size gas and steam combined cycle units;

Acceptance test of 9FA combined cycle unit and suggestions on plant operation;

Technical features of Siemens HE type combined cycle steam turbine;

Surplus BFG/COG-based combined cycle power plant for Maanshan Iron & Steel Co.Ltd;

It is pointed out that low pressure steam generation will be excess when the unit is running at low load condition in a combined cycle power plant consisting of a single-pressure ST and dual-pressure HRSG.

The cost of combined cycle power plant is one of the key factors that limit its development.

Control characteristics and Commission of GTCC;

This paper take BanShan natural gas electricity generation project 9FA GTCC unit as an example,summarized the network of GE MARK VI and Ovation DCS control system,analyzed the ethernet communication problems between this two system,then aimed at this questions to give the feasible solution.

Now, many GTCC power plants put into production along with the "West-East natural gas transmission" project.

The pressurized fluidized bed combined circulation cogeneration of heat and power to be adopted at Taishan thermal power plant ,Dalian is described,and such factors having effect on system thermal mechanics as process air,excess air,PFB temperature,desulphurization efficiency and Ca /S mole ratio,are analysed.

The developing trend of large scale gas turbine combined circulation is forecasted.

In terms of energy-saving,environmental protection,conservation of natural resources and improving the ratio of utilization of heat energy,the successful experiences of the energy efficiency of two-engine combined circulation thermal engine group were adopted and two engines were simplified into the turbine engine with "two working substance" conbined circulation.
