ABOUT KSTPS
KSTPS is first coal based power plant in Rajasthan.
It is located ideally on the left bank of chambal river at the upstream of kota barrage.
In 1973 Central Electricity Authority prepared a project report for power station.
In 1976 Planning Commission cleared project report.
Its first unit of capacity 110 MW is synchronized on 17 jan 1983.
GENERAL LAYOUT AND BASIC IDEA:
The conversion from coal to electricity takes place in three stages.
Stage 1
The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat.
Stage 2
The second stage is the thermodynamic process.
The heat from combustion of the coal boils water in the boiler to produce steam. In modern power plant, boilers produce steam at a high pressure and temperature.
The steam is then piped to a turbine.
The high pressure steam impinges and expands across a number of sets of blades in the turbine.
SALIENT FEATURES
The coal is brought to the KSTPS from BHARAT COKING COAL LTD.
There are 14 tracks for transportation.
Everyday 3- 4 trains of coal are unloaded, each train consists 58 wagons.
Coal is unloaded from wagons by means of WAGON TRIPPLER.
a. Wagons are rotated upside down through an angle 180 degree.
b. The unloaded coal is transported to crusher house with the help of conveyer belts.
BOILER
Boiler is a closed vessel in which water, under pressure, is converted into steam by absorbing heat released in process of combustion.
In KSTPS boiler used is water tube; pulverised fuel fired; single drum type; tangential firing system.
