Gas Turbine Power Plant

Gas Turbine Power Plant: A generating station which employs gas turbine as the prime mover for the generation of electrical energy is known as a gas turbine power plant In a gas turbine power plant, air is used as the working fluid. The air is compressed by the compressor and is led to the combustion […]

Nuclear Power Station

Nuclear Power Station: A generating station in which nuclear energy is converted into electrical energy is known as a nuclear power station. In nuclear power station, heavy elements such as Uranium (U235) or Thorium (Th232) are sub­jected to nuclear fission in a special apparatus known as a reactor. The heat energy thus released is utilised […]

Diesel Power Station

Diesel Power Station: A generating station in which diesel engine is used as the prime mover for the generation of electrical energy is known as diesel power station. In a diesel power station, diesel engine is used as the prime mover. The diesel burns inside the engine and the products of this combustion act as the “working fluid” […]

Hydroelectric Power Station

Hydroelectric Power Station: A Generating station which utilizes the potential energy of water at a high level for the generation of electrical energy is known as a Hydroelectric Power Station Hydroelectric Power Station stations are generally located in hilly areas where dams can be built conve­niently and large water reservoirs can be obtained. In a Hydroelectric […]

Steam Turbine Efficiency

Steam Turbine Efficiency: Steam Turbine Efficiency – The overall efficiency of a steam power station is quite low (about 29%) due mainly to two reasons. Firstly, a huge amount of heat is lost in the condenser and secondly heat losses occur at various stages of the plant. The heat lost in the condenser, cannot be […]

Schematic Arrangement of Steam Power Station

Schematic Arrangement of Steam Power Station: Although steam power station simply involves the conversion of heat of coal combustion into electri­cal energy, yet it embraces many arrangements for proper working and efficiency. The schematic arrangement of a modern steam power station is shown in Fig. 2.1. The whole arrangement can be divided into the following […]
