Combined Gas Turbine Cycle Power Plants The temperatures of gas turbine exhaust lies between the range of 400° C to 525° C with stygen content ranging from 15 to 18 % depending upon the air-fuel ratios used. Therefore, it spetsible to utilise the large heat content of the turbine exhaust effectively in a heat recovery … Read more
Concentrating Type Collectors Concentrating type of collectors are also known as focusing collectors. These type of collectors are used when the temperatures higher than 100° C are required. Therefore in these collectors, it is necessary to concentrate and collect the high intensity of solar radiations on the absorber surface. The collector system comprises of a … Read more
Types of Solar Concentrating Collectors The concentrating type of collectors can be broadly classified into following two categories 1. Focusing type or concentrating type collectors : In these type of collectors, the optical system focuses the solar radiations on to the absorber. These are further classified as : (a) Line focusing type concentrators. (b) Point … Read more
Comparison of Gas Turbine and I.C. Engines Sr. No. Gas turbine I.C. Engines 1. The weight of gas turbine per kW power developed is low since the working pressures are low required lighter construction. The weight of I.C. engine per kW power developed is high since the working pressures are high requiring heavy construction. 2. … Read more
Cogeneration Co-generation means the sequential conversion of energy of fuel into two or more forms. With regard to thermal power plants, the co-generation can be defined as the simultaneous generation and utilization of both power and heat. In a conventional power plant, the efficiency of power generation is about 35% and the remainder of 65% … Read more
Gas Turbine Power Plants Gas turbine power plants finds its application in aircraft, in the industries for driving various machines likes compressors, pumps and the mechanical equipment, transportation and for power generation both as base load and peak load plant. First central power plant based on gas turbine was built in 1977 thereafter tremendous development … Read more
Components and Accessories of a Gas Turbine Power Plant Components : The main components of a gas turbine power plant are compressor, combustor, gas turbine with auxiliary components as intercoolers and regenerators. Some of these are described below. 1. Combustion chamber (Combustor) : Various requirements of a combustion chamber are : Carryout complete combustion of … Read more
Operation of Gas Turbines The operation of gas turbine includes the starting and shut down. 1. Starting of gas turbine : The gas turbines are not self starting type. Because, in a gas turbine power plant, the air from surroundings needs to be inducted into the compressor to raise its pressure and the high temperature … Read more
Fuels for Gas Turbine Power Plants Important properties of the fuel needed for gas turbine application are volatility, high calorific value, self lubrication property and its availability at low cost having no suspended impurities. Volatility of fuel should be such that it provides case of starting at low temperatures and burn with high combustion efficiency. … Read more
Selection of Site for Gas Turbine Power Plants Following points are considered for selection of site for gas turbine plants : Load centre : It should be located near the C.G. of loads to reduce transmission costs and the transmission losses. Availability of labour. Site should be away from localities since it is noisy in … Read more
