Indirect air heaters

STELA indirect air heaters are applied in processes where mixing of the flue gas with the air to be heated up is unrequested, e. g. when drying breadstuff with fuel oil. STELA indirect air heaters are certified by the German Technical Control Board and have a certified efficiency of 90 % with outlet temperatures up to 120 °C.

Hot air generation with indirect air heater

The indirect air heater consists of an outer casing, an intermediate casing against radiation
losses, gas passes and a closed combustion chamber made of highly heat-resistant steel,
which is arranged centrically in the casing. Here the heating energy is transmitted to the
fresh air only via the heat exchanger surfaces of the closed combustion chamber and the
gas passes. The cooled combustion gases are drawn off into the open air via a chimney.
Thus the hot air is completely free of flue gases.
