Our group also combines the resources of industry-leading names including SRM, Air Preheater Company, Kraftanlagen, Gadelius, Stein, PBS, and APEL. Air Preheater Company Ljungström® Air Preheater Arrangements Vertical Heaters These are the most common air preheaters, with the rotor mounted on a vertical shaft. There is a further naming convention depending on the direction of the gas flow. A Ljungström® Air Preheater where the gas flows from the bottom to the top LJUNGSTRÖM serves the thermal power plant market with two key applications: air preheaters and gas-gas heaters, based on our genuine Ljungström® technology p The Ljungstrom air preheater is a regenerative heat exchanger, invented in the 1920s and soon used throughout the world. Dr. Fredrik Ljungstrom, then technical director at Aktiebolaget Ljunstrom Angturbin, invented it for preheating combustion air in boiler plants, but the use has expanded to include energy recovery in combination with the removal of oxides of sulfur and nitrogen.

The soot blower is always on the cold end or gas outlet of the air preheater. A good many Ljungstrom units are vertical shaft, so below the unit

One is the Ljungstrom type with rotating matrix of heating elements and the other Davidson type  While a unit may contain multiple air preheaters of different types such as tubular and Ljungstrom types, our process focuses only on the tubular air heater.

This may be horizontal (now very common in power generation utilities) or vertical. Proven Air Preheater Design 4 Rotor Bearing In a vertical-type air preheater the rotor shaft transmits the load forces to the support bearing which is arranged at the bottom and supported on the center pillar of the structural steelwork. A guide bearing is located at the top of the shaft and fixed to the housing.
