Super Critical Boiler – Definition, Advantages and types: Super critical boiler is a boiler that operates at super critical pressure (high pressure) to increase the efficiency of the plant and to reduce the cost of electricity production. Normally, water tube boilers are generally preferred for high pressure. In this water tube boilers, the water is …

Site Selection of Steam Power Plant: The following consideration should be taken while site selection of steam power plant. 1. Availability of raw materials Huge quantity of coal and fuel are required to run a steam (thermal) power plant. Therefore, it is important to locate the plant as near as possible to the coal fields …
Layout of Modern Coal Power Plant or Steam Power Plant: In Coal Power Plant or Steam Power Plant, the water is converted into steam and the steam expanded in a turbine to produce kinetic energy which is converted into mechanical energy. The Coal Power Plant or Steam Power Plant has four major circuits by which …

Regenerative Cycle – Definition, Advantages and Methods: Regenerative Cycle – Assume 1 kg of steam is expanded in the turbine. Before complete amount of steam is expanded, some amount of steam (m kg) is extracted (this process is called bleeding) and utilized for heating the feedwater. So remaining amount of steam (1 – m) kg …

Reheat Cycle in Steam Power Plant: Reheat Cycle: If the dryness fraction of steam leaving the turbine is less than 0.88, then corrosion and erosion of turbine blades occur. To avoid this situation, reheat is used. In the reheat cycle in steam power plant, the expansion of steam takes place in one (or) more turbines. …
Rankine Cycle (Simple Steam Power Cycle): Rankine cycle is the theoretical cycle on which the steam turbine (engine) works. Boiler Refer the process (4) to (1): Feed water is passing to the boiler. Heat is added to the water in the boiler. The water gets heated and becomes dry saturated steam (or) super heated steam. …
