Course Description
The addition of gas turbine-based combined cycle power plants to supply new generating capacity continues to play a major role in the power industry. This technology is being adopted by all key players in the power industry because it offers high thermal efficiency, low emissions, low installed cost, flexibility in fuel selection, low operation and maintenance cost, short installation time, and high operating flexibility. A successful approach to providing technical services and engineering support is to address the operational and maintenance aspects involving the integrated functioning of the two thermodynamic cycles in a combined cycle power plant. The staff must understand the interrelationships between the combined cycle plant components and systems to efficiently operate the plant.
The Training Course Will Highlight ?
The candidates will be able to explain the effect of operating parameters such as firing temperatures, compressor pressure ratios, ambient temperature and pressure conditions, turbine exhaust temperatures and their effect on gas turbine efficiency/power output, and the combined cycle efficiency/power output. This course goes through the overview of a combined cycle gas turbine; this will be followed by the different types of Gas Turbine. This is then expanded on to give a detailed understanding of the performance and management of the operations of a combined cycle gas turbine.
