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

LAYOUT OF POWER PLANT

POWER PLANT MAINLY CONSISTS FOUR CIRCUIT :-

1. COAL AND ASH CIRCUIT

2. AIR AND FLUE GAS CIRCUIT

3. FEED WATER AND STEAM CIRCUIT

4. COOLING WATER CIRCUIT

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

GENERAL LAYOUT

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%

BOILER

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

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.

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.

STEAM TURBINE▪ Steam turbine is a rotating machine which converts kinetic energy of

the STEAM into mechanical energy.

▪ Type : Impulse Turbine

▪ Types of TURBINE according to steam flow

▪ High Pressure TURBINE : 25 blades and single flow

▪ Inter Mediate Pressure TURBINE : 17 blades and single flow

▪ Low Pressure TURBINE : 8 blades and double flow

SPECIFICATIONS

GENERATOR

• It converts mechanical energy into electrical energy.

• The generator is driven by directly coupled steam turbine at a speed of 3000 rpm.

• Phase connection : Double Star

• Active Power : 7,10,000 KW

• Rated Voltage : 1,000 +5 %

• Frequency : 50 Hz

• Cooling : Hydrogen cooling
