Lighter fuel-the gas turbine comes of age

Some profound changes are overcoming the technology of electricity generation. A combination of environmental, economic and technical factors is increasingly leading generators to favour the adoption of gas-turbine-based plant. The author discusses the reasons for the increased use of gas turbines and discusses their operating principles. The use of turbine exhaust gases for steam generation of direct heating (cogeneration plants) is also discussed as is the application of gas turbines to base load and gasification plants. Future prospects are mentioned
