State of the art analysis of small scale cogeneration units based on reciprocating engine and gas turbine

The main objective of this study has been to investigate the state of the art in the area of small scale based combined heat and power generation. Where the world status on the small-scale cogeneration system such as overview ,best commercial units ,current research & development and some interesting demonstration have been studied and discussed. Also the efficiency of the cogeneration unit has been studied with different types of fuel. Other aims have been to identify proper natural gas and biomass based CHP Technology and also to go through some case studies where the optimization of the plant was made by considering different technology by proper optimization method. The technology investigated the reciprocating engine and gas turbine (both internally and externally fired) , where both the natural gas and biomass are taken in to account.
