Course Highlights

The Advanced Technology Gas Turbines & Planned Optimization of Combined Cycle Power Plants course focuses on the design, general operation, and maintenance characteristics of gas and steam turbines in a combined cycle power plant with emphasis on the major plant components and the performance of the plant.

Overall design and operation concepts along with basic operation and maintenance problems for the various pieces of TurboMachinery (gas turbines, steam turbines, and boiler feed water pumps) are discussed.  Discussions and design parameters of the Heat Recovery and Steam Generating (HRSG) systems, the feed water heaters and the condensers are also included. 

Planned Optimization of the Combined Cycle Plant, for maximum efficiency and power is emphasized throughout the course.  Cycle efficiency and part load characteristics are discussed in-depth.
An emphasis is placed on providing practical information with minimal theory.  This part of the course is aimed at engineers and operational personnel who need a broad-based introduction to practical optimization, operation and design considerations of a major combined cycle power plant.  Discussion throughout the course especially of plant problems and optimization by the participants with the instructor and amongst themselves is encouraged so as to maximize the course experience.

The course also deals with the computation of the performance of the combined cycle power plant.  Course participants will be taken through the computations of the Combined Cycle Power Plant on software supplied and the proper correction factors applicable in all the sections of the plant.  Attendees should bring their lap top computers so that sample computations can be carried out in conjunction with the instructor.

DAY 5

SPECIAL SESSION
It is suggested that attendees bring their lap top computers to class this day, so sample computations can be carried out in conjunction with the instructor. Performance computations will be conducted as per various ASME PTC Codes. 

Combined Cycle Plant Performance

• Study of techniques for computing performance of the advanced gas turbines in design and off design operation and in combined cycle modes.  NOTE: Most new advanced gas turbines operate at very high turbine firing temperatures.  Thus variation in this firing temperature significantly affects the performance and life of the components in the hot section of the turbine.  The compressor pressure ratio is high which leads to a very narrow operation margin, thus making the turbine very susceptible to compressor fouling.  The turbine is also very sensitive to backpressure exerted on it by the heat recovery steam generator.  The pressure drop through the air filter and dirty compressors also results in major deterioration of the performance of the turbine, thus emphasis will be placed on this computation.
• Calculation of steam turbine computations. 
• Computing of the performance of the Steam Tables via workings of the Mollier Charts and the Steam Tables. 
• Discussion of correction factors of the steam turbine.
