Overall air leakages are found to be high at different points of the circuit | Arrest air leakages regularly by conducting maintenance of compressed air system consisting of the plant circuit, and fittings. | 76,927 | ₹6,07,725 | ₹1,20,000 | 3 |
BR - Boiler & Steam Line
Observation | Recommendation | Unit Savings | Annual Savings | Investment | ROI | Status |
---|---|---|---|---|---|---|
Specific Energy Consumption of the 80kW - Upcaster unit - 1 was found to be 0.709 kWh/kg of product drawn and Specific Energy Cost is Rs.5.6/kg, due to low draw rate | Optimize the loading of furnace by slightly increasing the draw rate from 20 m/hr to 26 m/hr and reduce specific energy consumption near to 0.5 kWh/kg and specific energy cost to Rs.3.95/kg | 107575 | ₹753022 | ₹ | ||
Energy loss as heat through un-insulated surfaces of the melting chamber of Up-caster Units - 1 and 2 | Provide thermal insulation to the melting chamber | 84684 | ₹669001 | ₹200000 | 4 |
MT - Motors
Observation | Recommendation | Unit Savings | Annual Savings | Investment | ROI | Status |
---|---|---|---|---|---|---|
Mechanical Power Transmission Slip found to be high in FPM - 3 machine | Reduce slip by changing conventional V-belt with cogged V - belt and reduce speed of drive in the existing VFD | 6351 | ₹50174 | ₹1500 | 1 |
TR - Transformer
Observation | Recommendation | Unit Savings | Annual Savings | Investment | ROI | Status |
---|---|---|---|---|---|---|
Losses are found to be higher than standard limits | Undergo routine maintenance, oil filtration, breather replacement, overall check-up etc. | 217073 | ₹1714875 | ₹40000 | 1 |
DG - Diesel Generator
Observation | Recommendation | Unit Savings | Annual Savings | Investment | ROI | Status |
---|---|---|---|---|---|---|
