The Ljungström Air Preheater is a regenerative heat exchanger, and comprises a slowly rotating rotor filled with heat transfer plates. The hot and cold gas ducts are arranged so that half of the rotor is in the flue gas duct and the other half is in the primary air duct which supplies combustion air to the furnace.

The performance of Ljungstrom Air Preheater is depended on the heat transfer element profiles. New profiles are being designed in such a way that these new profile elements must be improving the

Today, the Ljungström® Air Preheaters is more widely used than any other type of heat exchanger for comparable service and is available in a wide range of sizes to meet your needs. With over 15,000 Ljungström® Air Preheaters installed globally – 3x as many than other companies – we have grown to be largest provider of air preheater technology, the history of our company is the history of the air preheater.

The waste heat of the flue gas is thus recovered and used for heating the combustion air. Fredrik Ljungström's technology of the air preheater is implemented in a vast number of modern power stations around the world until this day, with total attributed worldwide fuel savings estimated at 4,960,000,000 tons of oil, "few inventions have been as successful in saving fuel as the Ljungström Air Preheater". LJUNGSTRÖM ® AIR PREHEATERS (APH) for Industrial Steam Generation We offer certified parts and components, upgrades and enhancements, or drop-in replacements that guarantee the optimal performance of your equipment. Tailored to Suit Your Business The Ljungström ® Air Preheater is available in a wide range of sizes to meet your needs.

This r eview p aper is based on theories an d co mplications related to air- preheater & the heat The Ljungström air pre-heater is a regenerative type of heat exchanger used for preheating the combustion air, mainly in thermal power plant. The warm gas and cool air ducts are arranged to allow both the flue gas and the inlet air to flow simultaneously through the air preheater.

LJUNGSTRÖM serves the thermal power plant market with two key applications: air preheaters and gas-gas heaters, based on our genuine Ljungström® technology p

Rotary Regenerative type Ljungstrom Air heat trap for the boiler system, a regenerative air preheater typically accounts for over 13494/2200 means a Ljungstrom air preheater with rotor diameter of 5 Sep 2017 PRNewswire/ -- LJUNGSTRÖM announces a strategic global partnership air preheaters (APH), in addition to the Ljungström® air preheater Abstract - The Ljungstrom air preheater is a regenerative type of heat exchanger used for preheating the air, mainly in thermal power plant.

The patented Sealeze adaptive brush sealing system provides a more effective, more durable adaptive preheater seal with lower life-cycle costs than conventional APH (air preheater) seals. Conventional air-to-gas sealing systems used on rotary air preheaters have evolved little from the metal strip configurations used on the first Ljungstrom APHs of a century ago. The apparatus disclosed herein is designed for removing solid deposits, which interfere with heat transfer, from the surface of the basket section in an air preheater.
