CONSERVATION OF ENERGY: |
(a) |
Energy conservation measures taken : |
|
Installed Super Heater for waste heat recovery, steam heating in dryer in place of kerosene heating and vapour absorption
Machine to create chilled water from waste heat.(Rayon & T.P. Sections). Installed gamma matrix, almag refractory, HR
Separator for Cement Mill-2 and VVVF dry at Power Plant 2. Modified sepol separator feeding scrapper plate in Cement
Mill-3. Increased Raw Mill in-let duct size & converted the sharp edges to smooth curve. Reduced grinding media filling
in the Mill. Eliminated Screw Conveyor of 22 KW from Cement Mill-3 circuit. Connected HR Separator of Cement Mill-3
outlet duct venting to Bag House Fan. Regulated the reject material of polycom back to circuit. Interlocked reverse Air Bag
House Fan start with bag house DP, Feed HR grit materials to Mill in-let and replaced gear box of Kiln-2. (Vasavadatta
Cement Section). Installed new Lime Stone secondary crusher of 400 TPH capacity for additional output per day. Modified
operating conditions in Kiln for easy grinding and reduced cyclone pressure drop in Coal Mill-1. (Kesoram Cement Section). Installed Variable Frequency Drives in various boiler feeds and utility water pumps, ID fans, high sensible air conditioners,
VAM in place of compressor chiller unit, centrifugal compressors in place of reciprocating compressors. DM water heated
through steam recovery from Tyre Curing presses. LP air used in place of MP air in boiler ash handling system. (Tyre
Sections). Modified / incorporated Variable Frequency Drives on cooling tower's water feed pumps and returned water
pumps of rectifier transformers cooling circuit. Installed energy efficient lights in place of HPMV lamps. Modified capacitor
bank and retained TOD meter in grid supply. (Hindusthan Heavy Chemicals Section). |
(b) |
Additional investment proposals, if any, being implemented for reduction of consumption of energy : |
|
Installation of mist cooling tower & vacuum ejectors to conserve water, application of Variable Frequency Drives in cooling
tower and mist condensers for saving steam.(Rayon & T.P. Sections). Installation of Roller Press and HR separator for
Line-I Cement Mill, rotoscale for coal dosing for Line-II & Kiln feed for Line-I, curing tanks for temperature control, XRF and
XRD for quality control and coal integration for Line-IV to Line-I to cut the shut down time. (Vasavadatta Cement Section).
Installation of N-2000 O-sepa in Cement Mill-3. Replacement of existing Kiln-II cooler with latest energy efficient cooler.
Reduction of pressure drop in Kiln-II pre-heater and Kiln-I C-Line no.II cyclone, fugitive dust emission in Cement Mill and
cool crusher and upgradation of blending silos for steady operation of Kilns. (Kesoram Cement Section). Installation of
Variable Frequency Drives in various utility pumps, auto on/off with line running feed back in dual extruders for chilled water
supply. Increase in suction line of all utility pumps, overhead line in close loop for chilled water return from plant equipment,
hot water recovery from curing presses. Condensate to be recovered from curing presses of Motor Cycle Plant and Tube
Plant. (Tyre Sections). |
(c) |
Impact of measures at (a) & (b) above for reduction of energy consumption and consequent impact on the cost of production of goods : |
|
Reduction in consumption of electricity and coal consumption per unit of production were witnessed in general having
favourable impact on the cost of production. |
(d) |
Total energy consumption and energy consumption per unit of production as per Form “A” of the Annexure in respect of
industries specified in the Schedule thereto. |
