Introduction of KSTPS In April 1973, Central Electricity Authority prepared a Project Report for power station comprising of the two units of each of capacity 110 MW The planning commission cleared the project report in Sept., 1976 for installation of two units each of 110 MW in first estimated cost of Rs. 143 Crores. These two units was manufactured by BHEL, Hyderabad.

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.
The impulse and the thrust created rotates the turbine. The steam is then condensed and pumped back into the boiler to repeat the cycle. Stage 3 In the third stage, rotation of the turbine rotates the generator rotor to produce electricity based of Faraday’s Principle of electromagnetic induction. Control system of station is based on Rankin Cycle. To increase the heat economy and efficiency we use number of modification in the plant.

The Kota Super Thermal Power Station is divided into four main circuits:- Fuel and Ash Circuit. Air and Gas Circuit. Feed water and Steam Circuit. Cooling Water Circuit.
A boiler is a closed vessel in which water or other fluid is heated. The heated or vaporized fluid exits the boiler for use in various processes or heating applications
HORIZONTAL , VERTICAL & INCLINED

STEAM PRESSURE-150 Kg/Cm2
STEAM TEMPERATURE : - 535-545 0C
OPERATE ON RANKINE CYCLE
COAL HANDLING PLANT The main coal sources for KTPS are SECL (South Eastern Coalfields Limited), ECL (Eastern Coalfield Limited) and BCCL (Bharat Coking Coal Limited). It costs approximate 2 crores of rupees per day including transportation expenses. coal is firstly unloaded from wagon by wagon triplers And then coal is crushed by crushers. And then coal is transformed to the boiler by magnetic pully.
Coal handling broadly divide into three sections: Wagon Unloading System. Crushing System. Conveying System.
ASH HANDLING PLANT Fuel and Ash Plant. Air and Gas Plant. Ash Disposal and & Dust Collection Plant.
