ROTATORY REGENERATIVE

ROTATORY REGENERATIVE
AIR HEATERS

Intended use:

Rotatory regenerative air heaters (РВП) are installed at steam boilers and are designated for heating the air coming to burner devices of boiler units due to exhaust flue gas heat utilization.

Design and function:

Rotatory regenerative air heaters consist of  a vertical pivoted rotor.  Rotatory air heaters are equipped with two tiers of heating stuffing  packaged in rotar cell-shaped bundles.

So as to reduce air cross-flows to gas, the rotatory air heater design includes an adjustable system of radial, axial and circular seals.

Rotor spinning is performed through an electromechanical drive with lantern-wheel gearing. The drive is equipped with a soft starter.

For safe and effective operation rotatory air heaters are equipped with a water washing device, a steam blasting device, a fire-fiting device, a rotor lifting device, etc.
