Reduction in SEC Performance in last 3 - Years

In Year 2016-17, both SEC & STEC have been increased from previous years due to;

✓ Low PRI of Kiln; 83.79% in Y’16 from 93% in Y’15 after 100% pet coke firing.

✓ Increased AFR consumption

✓ Low PRI of Kiln due to TA Duct failure in Dec 2016 (Kiln PRI-50%) and Jan 2017 (Kiln PRI-48%)

INNOVATIVE PROJECT -1 With Zero Investment Page 1 of 5

Plant : WD Title of the measure : Reduction in frequent

failure of primary diaphragm of solenoid valve by in-house modification in the design of solenoid valve by OEM

Category B New concept (risks taken/self driven / beyond OEM)

Description of the energy conservation measure:Solenoid valves are used in bag-filter to arrest andsupply of compressed air requirement as per thecommand given to solenoid valve based ondifferential pressure. Problem Faced:✓Frequent failure of Solenoid valve diaphragms(Model MEP114) has been increased drastically inmost of the bag filters which have beencommissioned with Solenoid valves of MEP 114.✓In most of the solenoid valves primary diaphragm(D114) plates are getting damaged.✓Secondary diaphragm (D 16) corners damagedwhich causes air leakages


INNOVATIVE PROJECT -1 Page 2 of 5

Identification of problem and root Cause Analysis✓ Diaphragm plates damaged due to designproblem in solenoid valves.✓Solenoid valve top covers are having segmentedgrooves at the centre, frequent on/off operationdiaphragm plates hitting the segmented grooves,resultant of this diaphragm plates are damaged.✓At ambient temperature secondary diaphragm(D16) corners shrinked due to poor rubber qualityresulting into air leakages.

Solution of the identified problem✓ Solenoid valve top plate segmented grooves havebeen remove by machining at our Workshop toavoid the impact between diaphragm plate andsegmented grooves during operation.✓ To avoid the shrinkage of diaphragms, we haveprocured Nitrile - Hyplon polymer rubberdiaphragms.

Electrical Energy Conservation Case Study Page 3 of 5



Execution & Implementation ✓Till date, 162 Nos. Segmented groove solenoid valve top plate with modified topplates have been replaced in phase manner. After replacement, Failure ofdiaphragms in the bag filters has been reduced drastically.

Result & Benefit

✓ Replaced 162 no. Of deformed solenoid valves costing Rs. 4500 each withmodified solenoid valves. Hereby saving of around INR 7,29,000.

✓ Due to frequent failure of diaphragm, compressed air bypasses directly throughthe pulse pipe. This causes sudden drop in receiver pressure due to which we have torun additional compressor to make up this pressure drop.

✓ Many process disturbances occurs due to decrease in compressed air pressure.

✓ Due to frequent failure of diaphragms bag filter doesn’t get sufficient compressedair pressure; which causes increase in pressure drop in the bag filters, resultingincrease in pressure drop leads to huge fugitive emission & power consumption inFan.

✓ Estimated compressed air saved after modification – 255 CFM

✓ Measured SEC of compressed air generation @ 6.5 Kg/cm2(g) – 0.225 KW /CFM

Mill – Make LOESCHE – LM 43.4 by optimising during Petcock grinding by in-house modification.

Category B New concept (risks taken/self driven / beyond OEM)

Description of the energy conservation measure:Petcoke is grinding in existing coal VRM tomeet the requirement of 100% petcoke in kilnline–K4 of capacity 12500tpd Problem Faced:✓ Tackle process issues related to separategrinding of coal/petcoke and✓ Improve control of residue and kiln mainburner.✓ High Mill body vibration during petcokegrinding i.e. 25 mm/s✓ Frequent tripping on account of highvibration,✓ Low throughput during petcoke grinding



Solution of the identified problem

✓ Damring height changed from 50 mm to 75 mm

✓ Modification of water spray system from outlet to mill table for bed

stabilization.

✓ Product Fineness maintained at 3% - Residue at 90 µ.

✓ False air arrested

Result & Benefit

✓ After necessary modification & optimisation; presently coal mill is runningwith throughput of 69-70 TPH of Petcoke grnding at Product Finenessmaintained at 3% - Residue at 90 µ and Mill separator at 960 RPM.

✓ Present Mill body vibration is around 5-6mm/sec.

✓ SEC kWh/t mat has been reduced from 50.46 in YTD’2016 to 40.98 inYTD’2017; resulting a reduction in SEC of 9.48 kWh/t mat.



Plant : WD` Title of the measure :

To produce the clinker with 100 % pet coke by replacing traditional fuel to reduce the clinkering cost.

Category A Known concept with Unique Application

Description of the energy conservation measure:

Fuel mix optimization to reduce Thermal energy cost. Present kiln line –K4 at ACC Wadi has a clinker production capacity of 12,500 TPD & is one of the biggest kiln in the world.

Problem Faced:

✓ Due to non / less availability of linkage coal, high cost E-auction coal;leads to increase in product cost.

✓ Grinding of Pet coke in Coal Mill was challenging due to high vibration.

✓ Low alkali sulphur ratio in clinker leads to heavy coating formation in kilnraiser duct.

✓ High dust formation in clinker leads to flushing in pan conveyor.
