In a Captive Power Plant, Power generated is used in Industry rather than Supply to Grid.
In Combined Power Plant, Electricity is generated by Gas Turbine / Generator. Heat is recovered from Exhaust Gas and Steam is Generated.Steam is used to run Steam Turbine Generator and Electricity is generated by it also.
Co Generation Plant generates Power as well as Steam.
Impurities make water conducting. As such water is not conducting.
Condenser in TPS reduces Temp of Cold Reservoir increasing Efficiency and Power Output.
