F-EE-012 Combined Cycle Power Plant (CCPP) Operation Gas Turbine-Part 2 2019-02-11T09:57:33+00:00

Project Description

This ten (10) days course is for anyone new into the power industry wishing to gain knowledge of gas turbines and their application. Also personnel advancing to a control room post in a Combined Cycle Gas Turbine (CCGT) Power Plant. On completion of the course you will be able to demonstrate a basic understanding of the design and operation of CCPP

Why attend

This ten (10) days course for Combined Cycle Power Plant (CCPP) Operation Gas Turbine discusses the advancement in the areas of design, fabrication, installation, operation, and maintenance of gas turbines. This course was prepared to better answer today’s problems in the design, fabrication, installation, operation, and maintenance of gas turbines. This course has addressed most of the new developments and maintenance practices, in areas such as lubrication and controls for gas turbines over the past four years.

The use of gas turbines in the petrochemical, power generation, and offshore industries has mushroomed in the past few years. The power industry in the past 10 years has embraced the combined cycle power plants, and the new high-efficiency gas turbines are at the center of this growth segment of the industry. However, owing to the spiralling costs of natural gas, many of these plants designed for base load service have been cycled on a daily basis from part loads of 50% to full load, and in many cases, have had to be shutdown at weekends. The new maintenance chapters, with their case histories, should be of great assistance to the engineers in the field who have to operate their plant at other than design conditions of base loaded operation. Investigation into operation of these plants on other fuels is also covered in this edition.

Understanding gas turbine performance is of paramount importance, particularly in a deregulated market in order to minimize life cycle costs. Much of this can be elegantly illustrated by using simulators. However, such simulators need to address not only engine performance (including power augmentation and enhancement) but must also include deterioration, emission, turbine creep life usage, controls and life cycle cost analysis.

GPAL Single and two Shaft Gas Turbine simulators achieve all of this and they are probably the first of its kind. In Version 2, we have integrated the simulation of Turbine Inlet Cooling (TIC). Two TIC technologies are included – evaporative cooling (using wetted media and fogging) and chillers. As a consequence, the effects of humidity on engine performance and particularly on gas turbine emissions is now included. The outputs from the turbine inlet cooling simulation can be scaled to any gas turbine and it is therefore a powerful tool to investigate the suitability of turbine inlet cooling for any gas turbine for a particular site.

This ten (10) days course is class room based and focusses on the core principles of CCGT plant operation, including:

 Overview of CCPP and CHP installations.
 Legislation and environmental factors.
 Thermodynamics for Combined Cycles.
 Resume of Gas Turbines and other prime movers.
 Heat recovery boilers design and construction.
 Auxiliary boilers design and construction.
 Feed systems.
 Steam Turbine Plant.
 Condensers and cooling systems.
 Water treatment/chemical control.
 Combustion theory.
 Resume of electrical theory and alternators.
 Aspects of Power Plant efficiency.
 Instrumentation and control.
 Operation of units of modular layout.
 Safety, plant care and fire systems.
