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. 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. What is a Ljungstrom Air Preheater? An air preheater absorbs waste heat from flue gas, then transfers this heat to incoming cold air by means of continuously rotating heat transfer elements of specially formed metal plates.
