INTRODUCTION OF KSTPS
▪ LOCATION:-
It is located on the left bank of the CHAMBAL river
▪ BASED ON RANKINE CYCLE:-
A thermal power plant is a power plant in which the prime mover is steam. Water is heated, turns into steam and spins a turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.
▪ TOTAL GENERATING CAPACITY:- 1240 MW

The pulverized coal
is fed to the boiler
by conveyor belts
From the coal storageplant, coal is delivered
to the coalhandling
plant where it ispulverized

BOILER
▪ Boiler is a place where water is being converted into steam with burning of coal.
▪ It is closed vessel in which water under high pressure converted into steam.
▪ Type : Water Tube Boiler
▪ Capacity : 375 tons per hour
▪ Steam temperature : 540 °C
▪ Steam pressure :139gm/Cm2
▪ Efficiency : 86.6%

WATER TREATMENT PLANT
▪ Pressure filter removes impurities from raw water.
▪ Carbon filter removes excess chlorine from clarified water.
▪ Demineralizing treatment plant removes dissolved impurities from clarified water.
▪ Conductivity, pH & silica content of this water must be checked time to time.

ECONOMISER
▪ Flue gases coming out of the boiler carries lot of heat.
▪ Economiser uses this heat and heats feed water before entering into the boiler.
▪ It improves the efficiency of plant 10-12%.
▪ Temperature : 315 °C
![Page 12: KOTA SUPER THERMAL POWER STATION PPT](https://reader034.vdocuments.site/reader034/viewer/2022042503/55a205071a28abda648b45fe/html5/thumbnails/12.jpg)
AIR PRE-HEATER
▪ Air Pre-Heater is used to preheat the air before entering into furnace.
▪ It recovers the heat of flue gases coming from Economiser.
![Page 13: KOTA SUPER THERMAL POWER STATION PPT](https://reader034.vdocuments.site/reader034/viewer/2022042503/55a205071a28abda648b45fe/html5/thumbnails/13.jpg)
SUPER HEATER
▪ Super Heater is used to remove the moisture content from the steam.
▪ It raises the temperature of steam.
▪ Advantage:
▪ Increase efficiency
▪ Reduces corrosion of turbine blades.

CONDENSER
▪ It reduce the turbine exhaust pressure so as to increase the specific output of the turbine.
▪ It recover high quality feed water in the firm of condensate and feed it back to the steam generator without any further treatment.

DE-ARATOR
▪ The condensed water is passed by a feed pump through a Dearater.
▪ It is used to remove extra air and non-condensable gases are removed from the hot water to avoid pitting / oxidation.
