Cogeneration Engine Diagram. Gas engine cogeneration system cogeneration is a system that uses energy effectively by generating multiple types of energy such as electricity hot water and steam from a single energy source such as natural gas. Diesel engine power plants are installed where supply of coal and water is not available in sufficient quantity.
The hot exhaust gas from the gas engine can also be used as an energy source for steam generation which can then be utilised as an energy source for a highly efficient double effect steam chiller. How much more efficient is combined heat and power. Cogeneration engine exhaust gases have a high temperature ranging from 400 to 500 c.
Combined heat and power chp also known as cogeneration is.
Cogeneration is a highly efficient form of energy conversion and using gas engines it can achieve primary energy savings of approximately 40 compared to the separate purchase of electricity from the electricity grid and gas for use in a boiler. Cogeneration or chp combined heat and power and trigeneration tap the full potential of on site power generation to manage overall energy consumption for commercial buildings manufacturers healthcare facilities college campuses military bases and other government and industrial enterprisesby capturing the heat that is normally lost during power generation a. In this way the year round capacity utilisation and the overall efficiency of the. Combined heat and power chp is the simultaneous cogeneration of electricity and heat.
