Sourcing, Mapping, Transportation, Safety,
Suitability, Testing, Feeding, Trial burn of AF as per guidelines of
CPCB/SPCB, CAPEX, TSR, GAV, Cost feasibility, Risk assessment etc.
ACHIEVEMENT
 Commissioning of 3500 TPD plant.
PROBLEMFACED AND THEIRSOLUTION
 PHREATER FAN DAMPERNOT OPENED FULLY
During commissioning time, We were unable to increase feed due to
low feeding of coal in main and calciner due to CO,inspite of increasing
Preheater Fan speed. Then it was checked during shutdown, it was
found that Preheater Fan damper was only open 50% in 100% set
point, so after Preheater fan damper calibration, we were able to
increase feed.
 PREHEATER FAN VIBRATION
During commissioning time,So we were founding DE vibration high, so
we thought that it is due to high speed and high temperature, so we
restricted both speed and temperature, then it was checked that,it was
due to damage of DE fan bearing. So we replaced the bearing , then we
were able to increasespeed and feed.
 PREHEATER FAN BEARING TEMPERATURE HIGH
During commissioning time, we were facing Preheater Fan bearing
temperature high, inspite of greasing the bearing. So we were unable to
increase speed of Preheater Fan. So, after installing forced oil
lubrication, wewere able to shortout this problem.
 COOLER EXHAUST TEMPERATURE HIGH
During commissioning time, it was so high that CV Fan was tripping, So
after installing fresh air damper in cooler O/L duct , proper clinker
Nodulisation with increasing flux in raw mix and replacing with high
capacity cooler fans.

5.  COOLER FANS LOAD
By removing last three cooler fans damper , we were able to decrease
cooler fans load by removing cooler fans damper restriction.
 In house modification for solving problem of snowman formation in
KIDS area (static grate)
 By converting plane horseshoeto inclined horseshoe.
 By moving Burner Tip forward insidekiln.
 By installing moreblaster at snow man formation point
 Raw Mix Change
By increasing Fe2O3 content( 2.3 to 2.6% ) in Raw Mix , We were able
to increase feed.
 KILN I/L MATERIAL DROPPING
This problemwas solved by increasing height of tounge plate.
 KILN I/L JAM DUETO USE OF PET COKE
This problem was shorted out by regularly cleaning Kiln Inlet twice in a
shift with useof UT pump.
 Cyclone 6 Gas temperature was increased for increasing feed from 780
to 845 degree centigrade.
 Firing PD blower speed increased from 65% to 80% for increasing
Burning zone temperature and feed.
 Hood pressure slightly negative for decreasing false air from cooler and
O/L seal.
 Refractory life of cooler was increased by keeping hood pressure slightly
negative.
 ROLL CRUSHER( CLINKER CRUSHER ) BEARING TEMPERATURE
During commissioning time , Roll crusher (clinker crusher) bearing
temperature was increased due to hot clinker and pressurisation.
This problemwas solved by installing water jacketfor roller bearing .
 Cooler Grate load, Cooler O/L temperature and clinker
temperature was controlled by replacing cooler grate cooler
fans.
 KILNTORQUECONTROL
Kiln torque was controlled by replacing Kiln main drive gear box.
 WHR (wasteheat recovery) commissioned
12 MW power plant based on WHR was commissioned. The
generation cost (net) was 0.50 rupees/kwh.

6. For WHR system cooler hot gas was midtapped from cooler for
steam generation in boiler. At mid point temperature of hot gas was
around 400 degree centigrade.
 Shell temperature of Burning zone was controlled by fixing a row of
shell Cooling Fans between Ist and IInd tyre.
 Water spray in Ist cyclone and water spray in cooler was removed due
to coating formation. This problem was solved by replacing with fresh
air in downcomer ductand cooler outlet duct.
 OPTIMISATION OF COOLER
This was done by maximisation of air of cooler fans of KIDS area (static
grate).
 Excess Air control in Kiln
This was done by maintaining O2 level with minimum tolerable CO level.
 PREHEATER OUTLET O2
This was done by arresting false air in cyclone inspection door and duct
expansion joint.
 SILO PD BLOWERSETTING
This was done properly for optimum extraction of raw meal with setting
of startup and stop up time of PD blower.
 Coal residue optimised below 2% for proper combustion.
 COMMISSIONING OF COAL MILL
 Chain Feeder (3 kw) between Raw Coal hopper and Weigh Feeder
was removed by making a 20 degree slope of raw coal hopper
directly to weigh feeder.
 Coal Mill (Ball Mill) Fan speed optimised.
 Flap Damper between separator and chain feeder was optimised
by putting a weight on stick of flap damper.
 Coal flushing was solved by maintaining a proper clearance
between screw and cover.
 We have substantially reduced manufacturing cost / tonne of Clinker by
successfully implementation of AFR system inKiln.
 Production increased from2500 TPD to 3500 TPD
 Commissioning of Coal Mill
 Reduced Power Consumption of Kiln Section from 22 kwh/ t Clinker to 19
kwh/tClinker.
 Reduced Thermal Energy Consumption of Kiln from750 kcal/t Clinker to 700
kcal/t Clinker.

7.  Reduced Power Consumption of Coal Mill from 45 kwh/t Coal to 42 kwh/t
Coal.
SEMINAR
Participated in seminar on Renewable Sources of Energy and Energy Security
organised by Rajasthan State Centre Jaipur of IEI.
PROJECT TAKEN
 Manufacturing process and Heat exchanger (Rotary Kiln) Design of Red Oxide
Paint Plant.
