Deepakkumar Yadav 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
Advantages and Disadvantages of Gas Turbine Power Plants Advantages of Gas Turbine Power Plants : It is simple in construction. It is essentially, vibration fee being a rotary machine and having the continuous combustion. It runs at high speed thus it is smaller in size and has low weight to power ratio. Can use any type … Read more
Closed Cycle Gas Turbine Power Plant Schematic diagram of a simple closed cycle gas turbine power plant is shown in Figure. In this system the heat energy to compressed air is indirectly supplied in a heat exchanger called source. The heat energy of turbine exhaust gases is rejected in a heat exchanger called sink before … Read more
Modified Gas Turbine Power Plant A modified gas turbine cycle may have in addition to above an intercooler, a regenerator and a reheater. Such a gas turbine power plant is shown in Figure. Such a system is used to improve the performance of the plant. A regenerator is used to heat the compressed air by … Read more
Schematic Diagram of a Simple Gas Turbine Power Plant A simple gas turbine power plant working on open cycle is shown in Figure main components of the gas turbine cycle are : A compressor mounted on the same shaft or coupled to turbine. A combustion chamber called combustor. A gas turbine Auxiliaries such as fuel … Read more
Gas Turbine Materials Requirement and Selection Gas turbine power plants are designed to achieve high output and efficiency. To achieve this objective, these plants have to operate at high temperatures. Unlike diesel power plants, the components of a gas turbine power plant are exposed continuously to these high temperatures. Apart from this the blades of … Read more
Types of Diesel Engines and their Selection for Diesel Power Plants Diesel engines are generally classified as : Four stroke diesel engine in which one power stroke is developed every two revolutions of the crankshaft. Two stroke diesel engine in which we get one power stroke in every revolution of the crankshaft. Two stroke engines … Read more
Performance Curves of I.C Engines The engine speed of an engine is maintained constant with the help of governor and the load on the engine is varied. The variation of indicated thermal efficiency, mechanical efficiency and brake specific fuel consumption Vs percentage of load on the engine is shown in Figure A, B and C … Read more
Thermodynamic Analysis of I.C. Engines Before we carry out the thermodynamic analysis of the internal combustion (I.C.) engine cycles, it is desirable to carry out the energy balance of the engine system from first law of thermodynamics point of view. Such an energy balance will help us to understand the flow of energy input to … Read more
