ROTARY AIR HEATERS

ROTARY AIR HEATERS

Balcke-Dürr offers rotary Ljungström type air heaters as well as Rothemühle stationary heaters. Rotary air heaters are very important for increasing the efficiency and efficiency of boilers. Thanks to the thermal energy of the exhaust gas, the combustion air temperature is increased from the boiler. In the exchanger, flue gas and air flow in opposite directions through the heating elements. These elements continuously absorb and release heat through convection.

WHY IT IS WORTH MODERNIZING ROTARY AIR HEATERS

• Optimal boiler supply with hot air thanks to the appropriate cleaning of heating packages

• Lower fan power consumption and lower fuel costs due to optimized heat exchange and pressure drops in heating elements adapted to local conditions and reduced leakage

• Lower seal wear due to the high performance of the adjustable non-contact seal while reducing the mass flow rate of the leak

• Higher efficiency of the elements of the exhaust flow system (including dust extraction systems) thanks to the reduction of exhaust gases behind the air preheater
