Roadmap to reduce SEC to achieve benchmark (2017-18)
Problem : High power consumption of preheater fan close to motor rated power load at
900 rpm, cconstraint to increase clinker production more than 12000 TPD.
Project 1 : Modification of Preheater Fan Inlet Suction Box in Line-4 Kiln
Kaizen Idea Generated :
• To reduce pressure drop acrossduct by reducing velocity from 29to 21 m/sec.
• To modify bend before suctionbox which was leading theturbulence.
Root cause derived :
• There was a high velocity atpreheater fan inlet suction box29 to 30 m/sec which wasleading to high resistance(pressure drop 30 mmwg fromcommon downcomer to fan inletsuction box
Changes done
• Increased the width of suction box from 1010mm to 1350 mm. (Increased the area by 30 %.)
• Modified the suction expansion joint by usingthe existing expansion joint only.
Benefits Achieved :• Achieved dream figure of 12000 TPD kiln,
without taking fan out of SPRS
Project 2 : Hot Gas By-pass Duct from V-Separator to SKS Bottom in Line-4 Raw Mill Circuit.
17
Problem : Reduction in Air Loading/ Power Consumption of RABH Fans
In process of RC-IV plant optimization ,it was observed that
RABH fan motor loading was higher side i.e. Fan was
handling 15,70,000 m3/hr instead of 13,90,000 m3/hr
(design fig).Source of this excess air observed to be Fresh air
provided at Raw Mill Dynamic Separator bottom during mill
optimization as per suggestion by OEM to provide fresh air to
Dynamic Separator to increase separator efficiency for this
separator bottom plate was removed. This Fresh Air was
cause of higher amount of air handled by RABH Fan.

Actual Savings: This modification in Raw mill lead to spectacular saving in RABH fan motor loading, detail are :RABH fan loading of each fan before modification :- 370X2 KwhRABH fan loading of each fan after modification :- 279X2 Kwh in Mill -1,2&3 Total Saving in terms of KW for each RABH fan :- 90X2 =180 Kwh
Saving achieved is equivalent to 0.4 Kw/Ton ClinkerTotal saving in terms of Rs. – 41.40 Lakh/Year

Replication potential if necessary
Project 3 : Increase in Height of Cooler ESP Stack in Line-4 & Line-3
Problem: Cooler ESP fan power consumption was at higher side 0.5 kWh/t clk, than the India Benchmark
0.20 kWh/t clk
Kaizen Idea Generated :
• To reduce static head of fan by increasing thefan outlet pressure means chimney draft.
• To increase the stack effect i.e.✓ The gas inside the stack is around 90-105 deg
Celsius. The outside ambient air temperatureis around 30 to 35 deg Celsius.
✓ Consider this as two air columns connectedat the bottom. The high density and heaviercold air will be always pushing the lowdensity and lighter hot gases up.
✓ This causes the natural flow of gases up thestack. This pressure difference that pushesthe hot gas up the flue gas stack is calledstack effect.
Root cause derived :
• Cooler ESP fan operates at static pressure -60 to -90 mmwg with WHRS at 12000 TPDand in Line-3 Cooler ESP fan operates atstatic pressure -70 to -80 mmwg.
• With low draft in chimney -10 mmwg thestatic head increases 50 to 80 mmwg. Thishas direct impact on power consumption offan.
60 mtr in Line-4.
50.30 m in Line-3
Changes done:
• Increased the chimney height from 60 mtr to70.5 mtr. in Line-4
• Increased the chimney height from 50.30mtr to 57.5 mtr. In Line-3
57.50 m in Line-3
70.5 mtr. in Line 4
Benefits Achieved :In Line-4 Reduction in 40 kWh at sameproduction & WHRS generation level, due tothis head developed in case of WHRS isolationthe CV fan power consumption is minimalapprox.: 50 KWh.
In Line-3 Reduction in 42 kWh at sameproduction level, This reduction in power led tosubstitution of CV fan Motor from HT to LTMotor.
Project 4: Insulation on top stage (08 Nos) cyclones
19
Replication potential if necessaryProblem : To reduce Specific Heat Consumption by minimizing radiation losses in Preheater
• Case study of insulation on top stage cyclone has been done.(Idea taken from Shree Cement , Raipur)
• With application of Newton law of cooling excel simulation with different gastemp has been carried out at present hysil & refractory thickness.
