Recuperator
A recuperator is a heat recovery system that recovers the waste heat from hot flue gases emitted from the boiler’s flue and uses it to preheat the combustion air. Preheated air ensures more complete and efficient combustion; as fuel consumption and flue gas temperature decrease, boiler efficiency increases significantly. Manufactured from high-temperature-resistant materials, the unit is sized according to boiler capacity and can be adapted to existing systems. It is an efficiency investment that pays for itself in a short time through lower emissions and reduced operating costs.
RECUPERATOR (Flue Gas Heat Recovery System)
A recuperator is a heat recovery system that recovers the waste heat contained in hot flue gases discharged from a boiler’s flue into the atmosphere and uses it to preheat combustion air. It consists of a heat exchanger designed so that the flue gases and combustion air exchange heat across metal surfaces without mixing. This allows a significant portion of the heat that would normally be lost through the flue to be recovered and returned to the system.
Feeding the preheated combustion air into the furnace ensures that the fuel burns at a higher temperature and more completely. This increases combustion efficiency, reduces fuel consumption, and minimizes heat loss by lowering the flue gas temperature. The use of a recuperator results in a noticeable increase in boiler efficiency; since the amount of fuel consumed decreases, operating costs and emission levels are reduced.
The recuperator is sized according to the boiler’s capacity, flue gas flow rate, and temperature; it can also be adapted to existing boiler and flue systems. Manufactured from high-temperature-resistant materials, the unit stands out as an efficiency-enhancing investment in the boiler room thanks to its robust construction and long service life.
