A steam power station basically works on the Rankine cycle. Steam is produced in the boiler by utilizing the heat of coal combustion. The steam is then expanded in the prime mover (i.e., steam turbine) and is condensed in a condenser to be fed into the boiler again. The steam turbine drives the alternator which converts the mechanical energy of ...
THERMAL POWER PLANT - INTRODUCTION, COMPONENTS, PROCESSES ETC. In Thermal Power Station fuel burns & use the resultant to make the steam, which derives the turbo generator. The Fuel i.e. coal is burnt in pulverized from. The pressure energy of the steam produce is converted into mechanical energy with the help of turbine.
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.
the Bandel Thermal Power Station On February 29, 2012, WBPDCL, a power company in West Bengal, India, signed a contract with Doosan to enhance the performance of its ageing Bandel Thermal Power Station, which had been in operation for 30 years since its completion in 1982. Doosan was required to uprate the output of the existing turbine, increase
Economizer sends water to the Boiler. Boiler is the main part of any thermal power plant. It is used to convert water into steam. In any steam power plant water tube boiler is used. It contains furnace inside the boiler shell. The Coal burns into this section. Drum is major part of steam power plant boiler.
The Role of Thermal Power Plant in the Modern Power Generation Scenario. The development of thermal power plant in any country depends upon the available resources in that country. The hydro-power plant totally depends on the natural availability of the site and the hydrological cycle. The new sites cannot be created manually for hydropower plants.
Overall feature of a thermal power plant is exemplified in Fig. 3.1. This is the case of coal fired power plant. Coal is unloaded at the port and stacked on the coal yard or accumulated in a silo. Then coal is transported via belt conveyor to coal bunker. Coal mill pulverizes coal into a suitable particle size for injecting into a furnace.
As shown in the fig.1 the thermal power plant has the following area operations: A. Coal Handling Plant Coal transported to the plant by the rail line and carrier trucks. This coal is transfer from the underground bunker to crusher by series of conveyer belt. In coal crusher coal size
Thermal Power Plant Working: Thermal power plant is a place where electric power is generated by using a steam produced from high pressure boilers. In the boiler, water is converted into steam by using the heat of coal combustion. High pressure and high temperature steam produced in the process is made to hit the blades of steam turbine.
An economiser is a mechanical device which is used as a heat exchanger by preheating a fluid to reduce energy consumption. In a steam boiler, it is a heat ex-changer device that heats up fluids or recovers residual heat from the combustion product i.e. flue gases in thermal power plant before being released through the chimney. Flue gases are ...
Keywords: Economiser, Air Preheated, Boiler, Turbine, eff. (efficiency) INTRODUCTION A thermal power station is a power plant in which heat After it passes through the turbine, the steam is condensed energy is converted to electric power. It depends on the in condenser. And recycled where it was heated.
Working Principle of a Thermal Plant. The working fluid is water and steam. This is called feed water and steam cycle. The ideal Thermodynamic Cycle to which the operation of a Thermal Power Station closely resembles is the RANKINE CYCLE.. In a steam boiler, the water is heated up by burning the fuel in the air in the furnace, and the function of the boiler is to give dry superheated steam at ...
Internship on Thermal Power plant for Electrical Engineers . Pertecnica Engineering offers self financed internships to BE / B Tech (EEE) freshers and final year academic projects to Electrical engineering students on Power plants such as Thermal power plants, Combined cycle power plants, Bio-mass plants, Hydro electric plants etc in areas such as design, planning, procurement, erection ...
THERMAL POWER STATIONS Introduction Thermal energy is the major source of power generation in India. More than 60% of electric power is produced by steam plants in India. India has large deposit of coal (about 170 billion tonnes), 5th largest in world. Indian coals are classified as A-G grade coals.
An economiser is a mechanical device which is used as a heat exchanger by preheating a fluid to reduce energy consumption. In a steam boiler, it is a heat ex-changer device that heats up fluids or recovers residual heat from the combustion product i.e. flue gases in thermal power plant before being released through the chimney.Flue gases are the combustion exhaust gases produced at power ...
