This document provides an overview of the coal handling plant (CHP) at the NTPC Ramagundam power station in India. The NTPC is one of the largest power generation companies in India. The Ramagundam station has an installed capacity of 2,600 MW produced across three stages. Coal is a key fuel source and is transported via conveyors from storage to the plant. The CHP uses various safety systems for the conveyors like pull cord switches, belt sway switches, and chute block switches. It also employs technologies like stacker reclaimers and long travel drives to facilitate coal transportation. The summary provides a high-level view of the key details about NTPC, the Ramagundam plant

3. INTRO TO NTPC:
 National Thermal Power Corporation Ltd. is one of the
Maharatna companies Incorporated in 1975.
 NTPC is India’s largest power generation companies in
India.
 It is the sixth largest thermal power generating company in
the world.
 NTPC has 15-coal based and 7-gas based power stations.
Presently,it has an installed capacity of 44,304 MW.

4. RSTPS (RAMAGUNDAM SUPER THERMAL
POWER STATION).
 RSTPS was incorpoated in the year 1975.
 RSTPS installed capaity is 2600MW.
 The RSTPS consists of 3 stages
STAGE-I : 3X200 MW.
STAGE-II : 3X500 MW.
STAGE-III : 1X500 MW.
 The area of plant is 10,000 acres.
 The water is supplied through SRI PADA
YELLAMPALLI Reservoir.

5. POWER PLANT REQUIREMENTS.
 Coal/fuel availability: RSTPS obtains the coal from South Godavari coal
field of Singareni collieries for stage I & II and Korba coal fields of SECL
for stage III.
 Water requirement: SRI PADA YELLAMPALLI RESERVOIR.
 Ash disposal: Ash pod at Kundanapally ,5KM away from the plant.
 Evacuvation of power: The power generated from station is evacuated
through 9 no’s 400kV / 3 no’s of 220kV/ 2no’s of 132kV overhead
transmission lines.
 Distribution of power: The power generated is distributed to Andhra
pradesh,Telangana,Tamilnadu,Kerala and Pondicherry.

6. OVERVIEW OF CHP

8. INTRODUCTION TO CHP.
 In Thermal power plant coal is used as fuel.
 NTPC is maintaining MGR(merry go round) system
to transport the coal.
 Here wagons are unloaded in two ways:
i. Wagon tippler.
ii. Track hoper.

9. The coal is unloaded from a box type wagon by tilting
150deg angle.

11.  In this the wagons are bottom open type.
 To open and to close we use air compressors.

14.  CRUSHER HOUSE : Crusher house is used
to crush the coal to a size of 20mm.
The house consists of crusher blades.

15. CONVEYOR PROTECT SYSTEM.
 Pull cord switch : Pull cord switch is
used as a safety switch to stop
the conveyor emergency.
 Belt sway switch : The switch allows smooth running of
conveyor and protects it from overswaying due to uneven
loading of material.

16.  Chute block switch : Chute block switch is
used to monitor the chute
jamming in hopper & give early
warning of Belt Damage.
 Field & desk emergency push button : Emergency
push button is an electronic switch used to stop the
conveyor.

17. Interlock systems.
 Magnetic separator :
 Metal detector :

18. LONG TRAVEL DRIVE.
 STACKER RECLAIMER is a large machine
used to handle bulk material.
 Generally it is rated in tonnes per hour
(tph).
 It can usually move in 2 directions:
horizontal and vertical.

19.  There are 3 STACKER RECLAIMERS in RSTPS SR-1,SR-2,SR-3.
 Bucket wheels are used for digging the coal back and sending it to the boiler
when coal is required.

The target of NTPC is to achieve
75,000 MW by 2017.
In CHP most of the induction motors
are of squirrel cage motors.
In CHP fluid coupling of motors
employed.
 NTPC Ramagundam also has 10 MW
SOLAR POWER PLANT.
