Mar 04, 2020· Function of economiser in thermal power plant is to recover some of the heat from the heat carried away in the flue gases up the chimney and utilize for heating the feed water to the boiler. It is simply a heat ex-changer with hot flue gas on shell side and water on tube side with extended heating surface like Fins or Gills.

Boiler in a power plant has two functions. The Combustion system converts energy in coal to Heat. Water and steam system converts the heat to steam at high pressures and temperatures. This series explains the working of the boiler in modern power plant. How does …
Nov 28, 2017· An Economiser is a Boiler Accessory. Boiler Accessories are the machine components which are installed either inside or outside the boiler to increase the efficiency of the plant and to help in proper working of the plant. The function of economis
A power plant boiler, heat-transfer equipment, and auxiliary com-ponents can weigh nearly 11,000 metric tons, requiring the equivalent of 500 railroad cars to deliver the materials to the construction site (Kitto and Stultz, 2005). Current conventional coal EGUs can be designed as either sub-
Boiler feed pumps are crucial for the operation of power plants. These pumps are typically multistage and deliver feedwater to boilers. An example of a multistage boiler feed pump can be seen in Image 1. Feedwater is then turned into steam, which is what turns the turbines generating power at …
Swapan Basu, Ajay Kumar Debnath, in Power Plant Instrumentation and Control Handbook, 2015. 8.0 General. Auxiliary steam in a power plant plays a vital role during start-up of the boiler and turbine. In many plants with smaller and medium sized units there may be separate auxiliary steam headers for the boiler and turbine.
Surface Condenser and Its Function in Thermal Power Plant A surface condenser or steam condenser is a water-cooled shell and tube heat exchanger used to condensate the exhaust steam from the steam turbine in thermal power stations: the steam is converted from gaseous to liquid state at a pressure level below atmospheric pressure.
Types of Boilers Used in Power Plants 07-31 17:31:22 . A power plant or a power generating station, is basically an industrial location that is utilized for the generation and distribution of electric power in mass scale, usually in the order of several 1000 Watts.
Mar 21, 2014· Superheated steam is important because it increases the efficiency of the boiler. In the power generation industry it serves an additional crucial function: “drying out” the steam. It is important that dry steam is used for power generation because water …
A common application of economizers in steam power plant is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater. This raises the temperature of the boiler feedwater, lowering the needed energy input, in turn reducing the firing rates needed for the rated boiler output. Downvote (0) Reply (0)
Primary air ( pa fan) and Secondary air fan have an important role to play in fuel combustion and must be provided in different ratios according to the fuel quantity. PA or Primary Air fans are important item in a thermal plant ( boilers) as it lifts and carry coal to destination.
Thermal Power Station process flowchart and diagram. The fuel is transported from mines via trains to the fuel storage facility in a power plant. The fuel transported to the plant is generally bigger in particle size and before it is fed to the boiler furnace it is broken down into smaller pieces using crushers.The fuel is then fed to the boiler generating a large amount of combustion heat.
Definition of BoilerSchematic diagram of typical coal-fired power plant steam generator highlighting the air preheater (APH) location. An air preheater (APH) is any device designed to heat air before another process (for example, combustion in a boiler) with the primary objective of increasing the thermal efficiency of the process.
