Summary:A rotor for an air preheater that comprises a vertical rotor post surrounded by a series of independent sector-shaped baskets. The baskets are each supported by the rotor post at a plurality of axially displaced locations radially outboard from the rotor post. Gravity acting upon each basket produces a force couple at the points of support whereby the uppermost point is in direct tension and the lowermost point is in direct compression thereby placing the load at the ends of the rotor post and obviating the necessity of a massive rotor post structure between points of support. Differential thermal deformation of the rotor and the rotor post will produce only a slight repositioning of related elements without producing cracking and failure of a rigid connecting bone therebetween.
