Working Principles of Supercritical Steam Generator — Supercritical boilers have been popular since the mid-20th century. Since then until now, this boiler is very popularly applied to power plants, replacing subcritical boilers. Supercritical boilers have several advantages not possessed by subcritical boilers: 1. The efficiency of the supercritical boiler is higher because to generate the same…
STEP-1 Received data from customer Steam output, feedwater inlet Fuel analysis, boiler type Power plant heat balance STEP-2 Boiler Thermal Sizing: Combustion, efficiency, steam output calculation, Furnace, Back pass & Cyclone sizing, Metal temperature calculation, Emission calculation, Air Heater Calculation, etc. Iteration with customer/steam turbine back to STEP-1 STEP-3 Pressure part material selection and ASME calculation &…
A nuclear power plant is a thermal power station; the heat source is a nuclear reactor. It is common in all regular thermal power stations; the heat is used to produce steam which initiatives a steam turbine associated to an electric generator and which produces electricity. To produce energy high amount of coal and petroleum are used….
A gas turbine is also known as combustion turbine. It is a type of internal combustion engine. And it consists of an upstream rotating compressor coupled with the downstream turbine and a combustion chamber. There are two types of gas turbines, which are used in the gas turbine power plant. High pressure turbine Low pressure turbine High…
Hydro Electric Power plants are classified according to water head available. They are High head power plant Medium head power plant Low head power plant High head power plant The water operating head is more than 70 meters, at that instance the plant is known as high head power plant. The prime movers are used…
Power plant engineering mainly deals with the study of energy. For the power generation it utilizes the energy. With the help of turbine we can generate the power. By using the prime movers large amount of power is generated in a layout or from the site so it is known as power plant. In the…
Boilers can be classified as follows: 1. According to the flow of water and hot gases – fire tube (or smoke tube) and water tube boilers. In fire tube boilers, hot gases pass through tubes which are surrounded with water. Examples: Vertical, Cochran, Lancashire and Locomotive boilers. There may be single tube as in case…
In Impulse Turbine, steam completely expands in the nozzle itself. Hence its pressure remains constant on both ends of the moving blades. In Reaction Turbine, Fixed blades act as nozzles. Hence steam expands both in fixed and moving blades continuously as it passes over them. Thus the pressure drop occurs gradually and continuously over both…
