Abstract
A trisector air preheater includes sector plates between the primary air sector and the flue gas sector and between the secondary air sector and the flue gas sector which are of a large size so as to provide double radial seals. However, the sector plate between the primary and secondary air sectors is small and provides only a single radial seal. The one smaller sector plate reduces the pressure drop through the air preheater while sacrificing increased leakage only between air sectors. The axial seal between the primary and secondary air sectors may be maintained at a double seal size.
