25 INNOVATIVE PROJECT -1 With Zero Investment Page 1 of 5 Plant : WD Category B New concept (risks taken/self driven / beyond OEM) 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 Description of the energy conservation measure: Solenoid valves are used in bag-filter to arrest and supply of compressed air requirement as per the command given to solenoid valve based on differential pressure. Problem Faced: Frequent failure of Solenoid valve diaphragms (Model MEP114) has been increased drastically in most of the bag filters which have been commissioned with Solenoid valves of MEP 114. In most of the solenoid valves primary diaphragm (D114) plates are getting damaged. Secondary diaphragm (D 16) corners damaged which causes air leakages

26 INNOVATIVE PROJECT -1 Page 2 of 5 Identification of problem and root Cause Analysis Diaphragm plates damaged due to design problem in solenoid valves. Solenoid valve top covers are having segmented grooves at the centre, frequent on/off operation diaphragm plates hitting the segmented grooves, resultant of this diaphragm plates are damaged. At ambient temperature secondary diaphragm (D16) corners shrinked due to poor rubber quality resulting into air leakages. Solution of the identified problem Solenoid valve top plate segmented grooves have been remove by machining at our Workshop to avoid the impact between diaphragm plate and segmented grooves during operation. To avoid the shrinkage of diaphragms, we have procured Nitrile - Hyplon polymer rubber diaphragms.

28 Electrical Energy Conservation Case Study Page 4 of 5 Execution & Implementation Till date, 162 Nos. Segmented groove solenoid valve top plate with modified top plates have been replaced in phase manner. After replacement, Failure of diaphragms in the bag filters has been reduced drastically. Result & Benefit Replaced 162 no. Of deformed solenoid valves costing Rs each with modified solenoid valves. Hereby saving of around INR 7,29,000. Due to frequent failure of diaphragm, compressed air bypasses directly through the pulse pipe. This causes sudden drop in receiver pressure due to which we have to run 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 compressed air pressure; which causes increase in pressure drop in the bag filters, resulting increase in pressure drop leads to huge fugitive emission & power consumption in Fan. Estimated compressed air saved after modification 255 CFM Measured SEC of compressed air 6.5 Kg/cm2(g) KW /CFM

30 INNOVATIVE PROJECT -2 With Zero Investment Page 1 of 4 Plant : WD` Category B New concept (risks taken/self driven / beyond OEM) Title of the measure : Reduction in SEC of Coal Mill Make LOESCHE LM 43.4 by optimising during Petcock grinding by in-house modification. Description of the energy conservation measure: Petcoke is grinding in existing coal VRM to meet the requirement of 100% petcoke in kiln line K4 of capacity 12500tpd Problem Faced: Tackle process issues related to separate grinding of coal/petcoke and Improve control of residue and kiln main burner. High Mill body vibration during petcoke grinding i.e. 25 mm/s Frequent tripping on account of high vibration, Low throughput during petcoke grinding

31 INNOVATIVE PROJECT -2 Page 2 of 4 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

32 Electrical Energy Conservation Case Study Page 3 of 4 Picture/ sketch before modification Picture/ sketch after modification (if available) (if available)

33 Electrical Energy Conservation Case Study Page 4 of 4 Result & Benefit After necessary modification & optimisation; presently coal mill is running with throughput of TPH of Petcoke grnding at Product Fineness maintained 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 in YTD 2016 to in YTD 2017; resulting a reduction in SEC of 9.48 kwh/t mat.

34 INNOVATIVE PROJECT -3 Page 1 of 4 Plant : WD` Title of the measure : Category A Known concept with Unique Application To produce the clinker with 100 % pet coke by replacing traditional fuel to reduce the clinkering cost. 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 kiln raiser duct. High dust formation in clinker leads to flushing in pan conveyor.

35 Problem Analysis and action taken Page 2 of 4 Problem 1. High vibration in Coal Mill. 2. Formation of coating in raiser duct. 3. Low burner momentum. 4. Flushing of clinker in pan conveyor tunnel due to fine clinker. Action taken 1.Increase the damring height 2. Water spray started on table. 3. Installation of GRR for main drive to reduce the speed of the mill. 1.Stared using high alkali content material in raw meal corrective to maintain A/S in clinker. 2.Installation of Cardox socket in kiln raiser duct to dislodge the coating. 3.Cyclone / Raiser duct air blaster sequence changed to auto mode. 1. Increase the Primary air fan RPM. 1. Increased alumina ratio for better nodulization. 2. Cooler operation mode changed from random to shuttle.

37 TANGIBLE IMPACT OF THE PROJECT Page 4 of 4 EASE OF IMPLEMENTATION High sulphur Pet coke can also be used in clinkerization. Plant can also run in stable with less than 0.8 A/S ratio. Pet coke being hard to grind, the desired fineness could be achieved by in house modification of coal mill 2. Frequency of hot meal sampling increased for close monitoring of the changes occurring in the system. Frequent coating formation in kiln inlet and raiser duct eliminated by installation of air blasters. Manual cleaning of coating in kiln inlet and raiser duct reduced due to installation of air blaster.
