GENERATION OF THERMAL ENERGY INTRODUCTION ABOUT THE PLANT
KBUNL
(Kanti Bijlee Utpadan Nigam Limited) which was formerly known as Vaishali Power Generating Company Ltd(VPGCL) is situated in kanti which is 12 km away from main town muzaffarpur.
It is totally coal fired Thermal power station.
There are two units of each 110MW installed capacity.
ABSTRACT
Any thermal power plant is converting the chemical energy of coal into electrical energy. The process involved for this conversion is based upon the modified Rankin cycle. The major components that are used to accomplish the modified Rankin cycle are:
Boiler feed pump,
The steam generator water walls (evaporator),
Steam generator super heaters,
Steam turbine,
Reheater,
Condenser,
Regenerative feed heaters etc.
All components of a power generating cycle are vital and critical in operation. In Modified Rankin cycle, the two most important aspects that is added are reheating & regenerative heating. By reheating we used to send the steam coming from exhaust of the turbine back to the reheater of the boiler so that its enthalpy increases and more work can be done by this steam the other purpose is to make steam dry so that no harm will be done to the blades of turbine.
In MTPS Kanti, we have three turbines in Tandem coupling namely one H.P Turbine, one I.P Turbine & one L.P Turbine coupled with the generator to which is synchronized with the grid to produce electricity at 50Hz.
In all my modesty, i wish to record here that a sincere attempt has been made for the presentation of this project report. I also trust that this study will not only prove to be of academic interest but also will be able to insight into the area of technical management.
An Overview
NTPC
NTPC was set up in 7th November 1975, the NAVRATNA power giant today generates more than one fourth of the total power in the country, ranked 5th largest power generating utility in the world, NTPC is the second most efficient in capacity utilization among the top ten thermal generating companies according to a survey conducted by Data monitor, United Kingdom. In a short span of two decades, NTPC has earn its prime status by setting up a total generating capacity of 22,249MW, with 19.14% of India’s operating capacity, the company generates 26.7% of country electricity through its 13 coal & 7 gas based power plants spread all over the country.
Today, country needs a 10% sustained growth in power generation to ensure the momentum for a 7% overall growth in the economy. Recognizing this, NTPC has committed itself to achieving the status of a 30,000MW plus company by the year 2007 and 40,000MW plus company by the year 2012 and power generating capacity addition programme of 51,000MW (including nuclear energy and non-conventional sources of energy) for the tenth plan.
NEW TECHNOLOGY
Super critical technology at NTPC Sipat project (3*600MW) to increase the efficiency of the cycle and to decrease the green house gas emission,
Closed cycle seawater cooling at Simhadri project for first time in India
Introduction of IGCC (Integrated gasified combined cycle) for clean and efficient utilization of coal.
ENVIROMENT MANAGEMENT
Liquid water treatment plants at Farakka and Kahalgaon.
Ash water recycling system at Kahalgaon and korba to reduce water requirement for ash disposal at these stations.
WORKING PRINCIPLE
The working principle of thermal power plant is based on Rankin cycle. A central steam station basically works on the Rankin cycle. Steam is produced in the boiler , is expanded in the prime mover (Turbine) and is condensed in a condenser to be fed into the boiIer.
PROCESS OF GENERATION OF ELECTRICITY
MTPS Kanti is a Thermal Power Plant. The functioning of every Thermal power plant is based on following process:-
1. Coal To Steam
2. Steam To Mechanical power
3. Power Generation, Transmission & Distribution.
Coal To Steam
Coal and water are the primary inputs to a thermal power plant.This process of conversion of water to steam by using heat energy produced by burning of coal by producing heat takes place in boiler and its auxiliaries. Coal burns in a furnace located at the bottom part of the boiler. Feed water is supplied to the boiler drum by boiler feed pumps, where water is heated and converted into saturated steam. This is further superheated in the super heaters.
Steam To Mechanical Power
This is the most important process of a power plant. The superheated steam produced in the boiler at high pressure and temperature is feed to the turbine giving up heat energy, which is transformed into mechanical energy on turbine shaft. Thus, mechanical power is obtained from the turbine shaft.
Power Generation, Transmission & Distribution
Mechanical power produced at the shaft of the turbine is used to rotate the rotor of an electrical generator that produces electrical power. The electric power produced by the generator is boosted to a high voltage by a generator transformer to reduce transmission losses. This power at EHV i.e. 400 KV is transmitted and distributed by EHV transmission lines.
Coal To Steam
We are taking coal from coal-yard as Wagon tippler load with the help of motor on which the conveyer belt is mounted. As Wagon tippler consist of rotor & pinion. The pinion use to rotate rotor. If in case Wagon tippler not working then mechanically coal is transfer into hopper to the belt. We supply coal in coal bunker watching the load on control room connected Ammeter & Voltmeter. Feeder is used to put coal on belt. Small motors are connected to belt for support. Coal being passed through metal detector after passing through metal detector it is passed through vibrating screen where coal of 5mm seperated from large coal ane fed to crusher then magnetic separator to remove iron particle from coal. Then fed to crusher to coal bunker
