What is Cogeneration ?

Cogeneration Definition

Cogeneration, or combined heat and power (CHP), is defined as a system that produces both electricity and heat from a single fuel source.

High Efficiency

• Cogeneration plants are highly efficient, with efficiency rates of 80-90%, compared to the 35% efficiency of conventional power plants.

  
  

• Environmental Benefits

• Cogeneration reduces emissions of pollutants and greenhouse gases, helping to combat climate change.

Economic Advantages

• Cogeneration helps to improve the efficiency of the plant.

• Cogeneration reduce air emissions of particulate matter, nitrous oxides, sulphur dioxide, mercury and carbon dioxide which would otherwise leads to greenhouse effect.

• It reduces cost of production and improve productivity.

• Cogeneration system helps to save water consumption and water costs.

• Cogeneration system is more economical as compared to conventional power plant.

Configuration of Cogeneration Plant

• Gas turbine Combine heat power plants which uses the waste heat in the flue gas emerging out of gas turbines.

• Steam turbine Combine heat power plants that use the heating system as the jet steam condenser for the steam turbine.

• Molten-carbonate fuel cells have a hot exhaust, very suitable for heating.

• Combined cycle power plants adapted for Combine Heat and Power.

Types of Cogeneration Plants

• Topping cycle power plant

• Bottoming cycle power plant
