The Rotary Regenerative Air Preheater (RAPH) consists of a central rotating-plate element within a casing that is divided into sectors containing seals around the element. The seals allow the element to rotate through all the sectors, but prevent gas leakage between sectors while providing separate gas air and flue gas paths through each sector.

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 smokebox contained, ahead of the funnel, a rotating-media air preheater warmed by the flue gases, turned by a drive taken from the draught fan turbine. The sector-shaped thing on the front of the smokebox is the drive to the friction rollers that rotated the preheater. Keywords: air pre heater, Ljungstrom air-preheater, heating elements, Reynolds number. ABSTRACT. This r eview p aper is based on theories an d co mplications related to air- preheater & the heat 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.

The ARVOS | Ljungström® Air Preheater is a rotary regenerative air to gas heat exchanger for steam generators. It was invented in the early part of the 20th Century as a means of recapturing heat escaping up the flue stack in boiler systems. The ARVOS | Ljungström® Air Preheater was named after its inventor Dr. Fredrik Ljungström, an engineer and technical designer from Sweden.

Introduction 1 The overall efficiency of a thermal power plant is increased by preheat the air before supplied to combustion chamber. If the incoming air for combustion is not preheated, then some additional energy must be supplied Fig.-1 Ljungstrom air preheater Ljungstrom air preheater [Fig.-1] is one of the important heat recovery systems in coal based thermal power plant which was invented by Ljungstrom in 1920[1]. A Warren study on Ljungstrom air preheater and his experimental results confirms that there is a reduction of 10% fuel consumption in Left: The Beyer-Ljungstrom Turbine Locomotive.
