22 September 2018

13. Renovation and Modernisation of KTPS stage-I unit No.1,2&3
Why R&M of Stage-I:
Unit 1, 2 &3 were commissioned between 1984 to 1990
Stage-I units were designed for SPM level 750mg/nm3
Now actual stack emission is to the tune of 1000 to 1500mg/Nm3
CPCB has been asking WBPDCL since 2011 to reduce emission level to the tune of 100mg/Nm3
WBPDCL has submitted a BG amounting 25Lakhs as guarantee for implementation of up gradation programme of ESP.
Accordingly WBPDCL submitted an action plan for implementation of up gradation of ESP. Completion of up gradation of all the three units by March 2017.
22 September 2018

14. Renovation and Modernisation of KTPS stage-I unit No.1,2&3
Why R&M of Stage-I:
Salient features of modified notification for environment protection Amendment rule-2015
Units installed before has to achieve the following –
SPM level-100mg/Nm3,
Sox Emission -600mg/Nm3
Nox emission- 600mg/Nm3
Stage-I units are installed with 5 mills capacity each 26MT/Hrs.
Stage-I units are designed to fire coal of GCV to the range 3800 to 4400kCal/Kg
Presently KTPS is firing coal to the range of 3400kCal/Kg
Load is restricted to maximum 140MW per unit firing of all 5 mills.
For getting full load with worse coal around 150MT/hrs coal firing is required.
Therefore to mitigate the above mentioned point DPR for R&M of KTPS stage-I has been prepared by M/s Steag

: Kfw informed GoWB that they are supporting for financial assistance to WBPDCL through DEA for R&M works
: Accordingly WBPDCL contracted kfw for sanctioning loan for executing the R&M works
: In 146th Board meeting WBPDCL Board approved for R&M projects of KTPS
: kfw sanctioned 80 Million Euro loan only for KTPS Unit No.3 R&M works
: GoWB informed GoI that the decision to go for R&M of KTSPS is put on hold until the completion of R&M of BTPS unit no.5
22 September 2018

17. INSTALLATION OF NEW WAGON TIPPLER AT KTPS
Salient features :
KTPS is having two WT and one Track Hopper
WTs are 30 years old and can unload only 8-10 wagons per hour.
Plant is suffering high detention time for unloading Nbox wagon and causing huge demurrage charge.
Yearly demurrage charge is Rs Crs.(( )
Charge paid due to manual unloading is Rs. 5.8Crs.( )
Proposed augmentation at CHP: Rota side WT, Side arm charger, Crusher House, associated conveying system
Capacity: 800TPH
New WT can unload NBox wagon per hour
Cost only for WT and associated system: 119.3Crs.
Cost of Railway infrastructure:12.53 Crs
Total Cost: Crs.
Pay Back period: 7 Years.

18. Bandel Thermal Power Station

19. R&M of BTPS Stage-I Unit No.1, 2, 3 & 4
BTPS unit No. 1 to 4 were commissioned way back in the year 1965/66.
Original capacity was 82.5MW each
In the year 2006 CEA de-rated the units and the revised capacity was declared as 60MW each
The units were designed to fire coal of GCV 5175kcal/Kg to achieve full load
Now a days average GCV of coal being fired is around 4000kcal/Kg
It is very difficult to load the machines beyond 45MW
No. of Mills per unit is 3 with capacity 19.5MT/hr
All the units have completed more than 3 lac running hours
Day to day problem faced are mill gear box mis -alignment and boiler tube failure
22 September 2018

20. R&M of BTPS Stage-I Unit No.1, 2, 3 & 4
After dismantling unit no 1 to 4, land available will be only 3.7 Acres.
This land can accommodate 1X210MW unit with NDCT
13th Plan onwards CEA is approving only supercritical unit that is 660MW and above. Which is not feasible in BTPS due to land constraints
To under take RLA studies of unit 1 to 4 as World Bank fund to the tune of 1Cr is already available and being undertaken.
After completion of RLA studies, modification to be undertaken so that the units can run smoothly till the balance residual life.
After completion of the balance life units are to be dismantle and land will be available for some other infrastructure use only
