Industrial Waste Heat Recovery Solutions for Boilers & Furnaces
Grandeh offers engineered Waste Heat Recovery Systems (WHRS) designed to capture and reuse thermal energy from boiler and furnace flue gases, significantly improving overall plant efficiency and reducing fuel consumption.
Our systems are developed for real industrial operating conditions – high dust loading, variable loads, fluctuating fuel quality, and continuous operation.
What is a Waste Heat Recovery System?
A Waste Heat Recovery System recovers unused heat from exhaust gases and converts it into useful energy such as:
- Preheated combustion air
- Hot water or boiler feedwater
- Process heating air
- Thermal oil heating
This recovered energy directly reduces fuel firing rates and operating costs.
Our Waste Heat Recovery Product Range
1. Air Preheater Systems
Designed to recover flue gas heat and preheat combustion air for boilers and furnaces.
- Steam Coil Air Preheaters (SCAPH)
- Combustion Air Preheaters
- High-Temperature Air Preheaters
- Customized air preheaters for solid, liquid, and gaseous fuels
Applications:
- AFBC / FBC boilers
- Package boilers
- Furnaces and dryers
2. Flue Gas Heat Recovery Units
Heat exchangers designed to recover sensible heat from exhaust gases and transfer it to process media.
- Flue gas to water heat recovery
- Flue gas to thermal oil heaters
- Non-condensing gas heat recovery units
Applications:
- Boiler feedwater heating
