Flue Gas Recuperators – Efficient Waste Heat Recovery
Flue gas recuperators are designed for recovering waste heat from gas furnaces and boilers with a high dust content. They are most commonly used in foundries, smelters, and glassworks, where they efficiently utilize thermal energy from flue gases for combustion-air preheating or heating production halls.
Principle and Technology of Flue Gas Recuperators
A tubular flue gas recuperator operates on the principle of transferring heat from hot flue gases to fresh combustion air, thereby increasing furnace efficiency and significantly reducing gas consumption.
Operational reliability is ensured by automatic regeneration of the heat transfer surface, achieved either through mechanical scrapers or pulse cleaning with compressed air. This maintains constant efficiency and ensures long service life of the equipment.
- Designed for flue gases with temperatures of 300–700 °C
- Durable stainless-steel construction for aggressive exhaust gases
- Integration capability with measurement and control systems (automation/MaR)
- Can be part of comprehensive flue gas filtration and cleaning technologiesSem můžete vložit Váš text.
Advantages of Flue Gas Recuperators
- Energy savings through preheating of combustion air
- Reduced emissions and more sustainable operation
- Stable efficiency thanks to automatic regeneration
- Long service life even in demanding conditions
The main difference compared to other flue gas–to–water heat exchangers lies in the specific function of flue gas recuperators, which are designed exclusively for heat transfer from flue gases to air (flue gas/air), while conventional heat exchangers typically operate in flue gas/water systems.
