A combined-cycle power plant uses both a gas and a steam turbine together to produce up to 50 percent more electricity from the same fuel than a traditional simple-cycle plant. The waste heat from the gas turbine is routed to the nearby steam turbine, which generates extra power.

This is how a combined-cycle plant works to produce electricity and captures waste heat from the gas turbine to increase efficiency and electrical output.

1. Gas turbine burns fuel.

  • The gas turbine compresses air and mixes it with fuel that is heated to a very high temperature. The hot air-fuel mixture moves through the gas turbine blades, making them spin.
  • The fast-spinning turbine drives a generator that converts a portion of the spinning energy into electricity.
  • SMPCL has installed two GE PG9171E-3 (9E.03) Gas Turbines

2. Heat recovery system captures exhaust.

  • A Heat Recovery Steam Generator (HRSG) captures exhaust heat from the gas turbine that would otherwise escape through the exhaust stack.
  • The HRSG creates steam from the gas turbine exhaust heat and delivers it to the steam turbine.
  • SMPCL has installed two HRSG manufactured by Hangzhou Boiler ;Model: NG-S209E-R

3. Steam turbine delivers additional electricity.

  • The steam turbine sends its energy to the generator drive shaft, where it is converted into additional electricity.
  • SMPCL has installed one Steam Turbine manufactured by Harbin Turbine Co. Ltd; Model: LN121-7.28/0.70/503/257.
