Fuel option for gas turbine

Growth in electricity demand is an average of 10% per year. Energy, emission, and economy are important critical concerns for generating systems. Therefore, combined cycle power plant is prefered for the Electricity Generating Authority of Thailand´s (EGAT) new power generating capacity. The various options of available fuel for gas turbines are natural gas, liquid fuel and coal fuel. Particularly with the tremendous price increases in imported and domestic fuel supplies, natural gas is an attractive low cost alternative for power generation. EGAT has studied and researched the use of heavy fuel instead of natural gas since the 1991. The problems of various corrosion characteristics have been found. In addition, fuel treatment for gas turbines are needed, and along with it, the environmental considerations are options that provide the limitation of environmental regulation
