A Boiler is a the biggest and most critical part of a thermal power plant. Definition of Boiler according to IBR Act 1923 (Indian Boiler Regulation), An steam boiler means any closed vessel exceeding 22.75 liters in capacity and which is used expressively for generating steam under pressure.
The boiler does not directly govern the amount of radiators fitted to the system. It is the power of the pump and circulation of the water through adequately sized pipes that determines the number of radiators you can have. But the total output of all the radiators, pipes, and cylinders determines the size of the boiler.
Aug 22, 2018 · Boiler or more specifically steam boiler is an essential part of thermal power plant.

Jun 08, 2019 · To enhance the thermal efficiency of the plant, the coal is used in the boiler in its pulverized form. In coal fired thermal power plant, steam is obtained in very high pressure inside the steam boiler by burning the pulverized coal. This steam is then super heated in the super heater to extreme high temperature.
Boiler. In Thermal Power Plant Boiler, Coal is burnt to heat up the water. The fuel is burnt inside the Boiler, whereas the water which is heated runs in tubes on the surface of the Boiler. Thermal Power Plant Boilers are different because of the complexity of the process and different types of system involve in the entire combustion process.
Thus, a thermal power station may sometimes called as a Steam Power Station. After the steam passes through the steam turbine, it is condensed in a condenser and again fed back into the boiler to become steam. This is known as ranking cycle. This article explains how electricity is generated in thermal power plants.
A thermal power station is a power station in which heat energy is converted to electric power. In most of the places in the world the turbine is steam-driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle. The greatest variation in the design of thermal power stations is due to the different heat sour
Mar 06, 2018 · TYPE OF HEAT LOSS IN BOILER AND THEIR PREVENTION . in this article we discussed about the Type of heat loss in boiler and their prevention. in power sector each boiler is not 100% efficient it has some losses so that the boiler efficiency remains up-to 75-80% in generally operating conditions and remaining 20-25 % are considered into loss . these losses reducing the performance of boiler as
