A melting furnace operating with exhaust gas temperatures of nearly 360°C was identified as a strong opportunity for Waste Heat Recovery. Instead of letting this energy escape to the atmosphere, the recovered heat was reused as pre-heated combustion air for the same furnace.
System Highlights
Fuel Used: PNG (Piped Natural Gas)
Consumption Before WHR: 90 SCM/hr
Operating Hours/Year: 6000 hrs
Flue Gas Inlet Temperature: 360°C
Flue Gas Outlet Temperature: 140°C
Heat Recovered: ~98,000 – 100,000 kcal/hr
Savings in PNG Consumption: ~11 SCM/hr
Annual PNG Savings: ~66,000 SCM
Annual Cash Savings: ~₹30 Lakhs
The project demonstrates how even a compact WHRS can deliver measurable fuel savings and attractive payback when engineered correctly.
