Spoked support ring for air preheater housing

摘要

A rotary regenerative air preheater has ring assemblies at the upper and lower ends which define the outer periphery and support the air preheater housing panels. The ring assemblies are spaced by spokes which are tied to the hub of the air preheater and vertically supported from the air preheater structural members. The rotor housing panels are attached around and between the spoked ring assemblies. The ring assemblies are formed form a series of uniform interchangeable segments and they support the peripheral bypass seals.
