Air heater profiles
Today’s resources economy is tomorrow’s well-being of our children
The regenerative air heater is used mainly in heat power engineering for large energy boilers, has in its design a heat exchange elements designed to perceive the heat of gases leaving the boiler and transferring it to the incoming air entering the furnace of the boiler.
The heat exchange elements are usually installed in the rotor of the regenerative rotating air heater (RAH) in the form of baskets in the cold and hot layers of the RAH. There is, as a rule, in 1 tier in the cold layer, in the hot layer from one to several tiers.
The complex reliable operation of the cold and hot layers with the corresponding parameters of the surface of the heat exchange sheets creates the basis for reliable operation of the RAH.
