GAS TURBINE What is a Gas Turbine? A gas turbine is a combustion engine at the heart of a power plant that can convert natural gas or other liquid fuels to mechanical energy How a Gas Turbine Produces Electricity? 1. Air-fuel mixture ignites 2. Hot gas spins turbine blades 3. Spinning blades turn the drive shaft 4. Turbine rotation powers the generator 5. Generator magnet causes electrons to move and creates electricity Major Components of a Gas Turbine • Compressors • Regenerators/Heat Exchangers • Combustors Compressor Function: A compressor is a device that pressurizes the working fluid Types of Compressors • Positive Displacement • Centrifugal • Axial Flow Regenerators Function: It acts as an air-to-gas heat exchanger Combustor Function: They increase the temperature of the high pressure gas Zones of a Combustor • Recirculation zone • Burning zone • Dilution zone
