Abstract
A transition element for providing an interface between a duct having a substantially rectangular cross section and an air preheater having a substantially circular cross section. The transition element includes an inner sidewall, an outer sidewall, and first and second end walls, where the outer sidewall and the first and second end walls form first and second transition corners. Each of the transition corners comprises first and second flow deflectors, each having an outer terminal edge and first and second side edges extending laterally from the terminal edge to an inner point. The first side edge of the first flow deflector is mounted to the second side edge of the second flow deflector and the outer terminal edges of the first and second flow deflectors are mounted to the duct to connect the air preheater to the duct.
