INNOVATIVE PROJECTS SUMMARY1. Erection of Isolation Gate at PA Fan Discharge Duct (FY 2018-19)
Impact:- Recently in Dec 2019 one PA fan of Unit#1 was under
breakdown for 15 days and with the help of this recently erected gate
Unit run continuously on 60-70% load instead of shutdown the Unit and
the damaged fan was attended in parallel.
2. Refractory Works in Economizer and LTSH Bends (FY 2017-18)
Perforated Plates (size-600X25X6MM) covered by refractory for
protecting bends from erosion due to flue gases.
Impact:- BTL due to erosion of bends from flue gases has been
controlled.
3. Shielding Plates in Heat Recovery Area (FY 2017-18)
Impact:- Erosion of bends from flue gases has been controlled.
18
INNOVATIVE PROJECTS1. Erection of Isolation Gate at PA Fan Discharge Duct FY 2018-19
Problem:-
During running of Unit, If any
one PA Fan goes under
breakdown, It required to be
isolated to attend the problem.
With available discharge
damper it was not possible to
isolate the PA Fan completely.
Due to Passing of air from
discharge damper PA Fan under
breakdown rotates in reverse
direction, due to which
maintenance work was not
possible and also it hurdles
when again PA Fan is required
to be taken in service.
Investment (Rs. In Lakhs):- 23.524
Annual savings (Rs. In Lakhs) :- 5873.76

INNOVATIVE PROJECTS3. Shielding Plates in Heat Recovery Area (FY 2017-18)
Project Details
Problem Action Taken
During Annual Shutdown while
carrying out De-metering of
Tubes and Bends in Heat
Recovery Area, It had been
Observed that Tubes and Bends
started eroding due to Impact of
Flue Gasses.
Provided SS (Stainless Steel) shielding
plates on tubes & bends in front Heat
Recovery Area for protecting erosion
of tubes and bends due to flue gases.
This arrangement was not provided by
OEM in original design.
Investment:- Rs. 3.38 Lakhs.
Estimated Annual Saving:- Rs. 3656.25 Lakhs
Replication Potential:- Yes. Can be explored by other plants also.

OTHER MODIFICATIONS1. Modification Done in Wet Bottom Ash Hopper (BAH) to avoid damage of
Refractory and Seal Trough
Original Drawing of BAHOEM -M/s Macawber Beekay Pvt. Ltd, Noida.
Modified Drawing of BAH
In consultation with OEM
Problem
Whenever Clinkers fall in Bottom Ash Hopper, It causes damage of refractoryon walls of bottom ash hoppers & seal trough due to explosion occurred bysplashing of water on the refractory of walls.
Impact
Frequent Occurrence of this phenomenon leads disturbance in furnace, whichfurther causes drastic variation in draft making Units unstable and prone totripping.
Sometimes this phenomenon may become cause of accident and human injuryalso.
23
OEM suggestion
Additional strengthening (by MS/SS angles, plates stiffeners & SS anchors
etc)
Result
Refractory of said portion has been carried out in both units but the problem
remains the same.
OTHER MODIFICATIONS1. Modification Done in Wet Bottom Ash Hopper (BAH) to avoid damage of
Refractory and Seal Trough
Result:- Frequent problem of damage of bottom ash
hoppers walls, seal trough, refractory etc. was resolved.
24
Our Observation
Main problem in the existing design
was rectangular portion of Bottom Ash
Hopper. At the time of explosion water
of bottom ash hopper spreads & strikes
on the walls of rectangular portion and
seal trough which resulting damage of
refractory of walls & seal trough of
bottom ash hopper.
Modifications done
The bottle neck portion of
bottom ash hopper was
minimized to provide
path/space (by providing
taper plates) for water
splashing during the falling of
clinkers in bottom ash
hoppers.

backwash & Cooling Tower Blow down through Effluent Treatment Plant.
Metering and measuring of water through flow meters at different
locations.
Treated waste water is used for Cooling Tower Make-Up.
For treatment of waste water Effluent Treatment Plant (ETP) is installed
of capacity 4033 KLD. Complete effluent is being recycled and Zero
Liquid Discharge concept is maintained. Treated waste water of ETP
clarifier is also used for gardening.
Treated waste water after passing through Reverse Osmosis is used for
production of De-Mineralised (DM) Water.

BEST PRACTICES ADOPTED AT KATPP
Previous Running of MDBFP during Cold
Start Up :- 20 to 23 hours
Practice Changed:-
In Current year only one TDBFP are being
run during cold and warm start up of units
in place of MDBFP if one unit is running
already to reduce APC.
Only two compressors are being kept in
service (1-SAC & 1-IAC) in place of
earlier practice of 3-nos. for reduction of
APC.
One CWP pump has been taken out from
service for full winter season and only two
CWPs are being run per unit (without
sacrificing vacuum) in place of earlier
practice of 3-nos.Reduction in APC.
38
BEST PRACTICES ADOPTED AT KATPP
All 03 Nos. of CPU are being
taken in service during unit start
up of unit which has reduced
time of DPR and helped in early
normalization / achieving full
load of unit.
Monitoring and Supervision at the time of turbine rolling and heat soaking
Maintaining controlled firing rate/ heat input
Result
Unit is being synchronized in 10 to 12 hours in comparison to previous
years’Unit synchronization time of 15 to 18 hours during the cold start up.
Reduction in Unit start up
and synchronization time,
during hot as well as cold
Start Up
Passing of steam through high energy drains to
condenser and to start up flash tank/ IBD have been
arrested / minimized.
More valves are being replaced immediately.
Reduced
Energy Losses
