Air preheater Wikipedia

Types. There are two types of air preheaters for use in steam generators in thermal power stations: One is a tubular type built into the boiler flue gas ducting, and the other is a regenerative air preheater. These may be arranged so the gas flows horizontally or vertically across the axis of rotation.

To optimize the design of the basket profile in Ljungstrom

Abstract The Ljungstrom air preheater is a regenerative type of heat exchanger used for preheating the air, mainly in thermal power plant. The warm flue gas and cold air ducts are arranged to allow both the flue gas and air to flow simultaneously through the air preheater. The hot flue gas heats the rotating profile and as it rotates, the hot section moves into the flow of cold air and

Ljungstrom Air Preheater ASME

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.
