Flue Gas Heaters
Flue gas heaters are specialized heat exchangers that recover energy from hot exhaust gases, improving efficiency and reducing waste. They are widely used in power plants, industrial boilers, and flue gas desulphurization systems to preheat air or reheat treated gases before release.

What Are Flue Gas Heaters?
-
Flue gas air preheaters: Devices that capture heat from boiler exhaust gases and transfer it to incoming combustion air. This boosts boiler efficiency by reducing fuel consumption.
-
Gas-gas heaters (GGH): Regenerative heat exchangers used in flue gas desulphurization (FGD) systems. They reheat cleaned flue gas before it exits the stack, preventing condensation and corrosion.
-
Gas room heaters (sometimes confused with flue gas heaters): Domestic appliances that use gas combustion to heat water or air for household use

Features:
- ā¢Energy efficiency: Recovering waste heat reduces fuel usage and operating costs.
- ā¢Environmental protection: Prevents acid condensation and corrosion in stacks, lowering emissions.
- ā¢Operational reliability: Keeps flue gas temperatures stable, protecting downstream equipment.
Flue gas heaters are not household appliances but industrial systems designed to recycle waste heat from exhaust gases. They play a crucial role in improving boiler efficiency, reducing emissions, and ensuring safe operation in power plants and heavy industries.
