INTRODUCTION:-
The function of thermal power plant is chemical energy of fuel is coverted into mechenical energy and after it the mechanical energy is converted into electricaal energy.
Electricity is an essential input in various sectors of an economy such as industry,agriculture as well as commercial and domestic sectors. In India, the electricity sector was a public monopoly and received high priority during the four decades of planned economic development in the country, before the onset of overall economic reforms in 1991.
Efficiency analysis:
-Efficiency analysis of coal-based thermal power generation in India 17Coal-based thermal power stations are the leading providers of electricity in India,followed by hydro,,thermal power plants have the largest share (more than 50%) of installed electricitygeneration capacity in the country, while their share in actual power generation in India iseven larger.
OVERALL PERFORMANCE:-
Energy loss on account of planned maintenance reduced to 5.66 % from 7.54 %during 2007-08.
The average duration of boiler overhaul and capital maintenance was achieved as 24 days and 53 days respectively.
Average duration of boiler overhaul in private sector was lowest (18 days). No private sector unit was taken for capital overhaul.
COAL HANDLING PLANT:-
SCOPE OF WORK:- The scope of coal handling plant typically covers the design, engineering, manufacture,inspection and testing at manufacturer's works, supply, packing and delivery at projectsite, unloading, storage and in plant transportation at site, erection, supervision, precommissioning,testing, successful commissioning, performance testing and handing overof coal handling plant of the thermal power project. Scope of work shall include allmechanical, electrical, C&I, accessories, civil, structural and architectural works to makethe system complete.
Advantages:-
1. fuel used is The quite cheap.
2. Less initial cost as compared to other generating plants.
3. It can beinstalled at any place iirespective of the existence of coal. The coal can be transported to the site of the plant by rail or road.
4. It require less space as compared to Hydro power plants.
5. Cost of generation is less than that of diesel power plants.
Disadvantages:-
1. It pollutes the atmosphere due to production of large amount of smoke and fumes.
2. It is costlier in running cost as compared to Hydro electric plants.
