A waste heat recovery is a process to recover heat from hot streams of energy from gases, water and/or cooling towers. An exhaust gas stream (with temperatures above 250°F) has significant potential to recover wasted heat.
Examples of recovery opportunities include:
- Plant process heating
- Combustion air preheating
- Boiler feedwater preheating
- building heat.
In addition to savings in everyday fuel consumption, many facilities can market and sell carbon credits back to industry.
State and / or federal funding is often available for waste heat recovery projects helping to reduce capital costs and expedite system payback.
