Abstract

1,045,974. Thermal regenerators. SVENSKA ROTOR MASKINER A.B. April 24, 1963 [April 26, 1962], No. 16109/63. Heading F4K. A rotary regenerative air preheater operable at low exhaust gas temperatures comprises a regenerator body having a framework carrying a heat exchanger mass and composed of two axially adjacent zones or portions, one of the portions being the hot end portion and the other portion being the cold end portion, the surfaces of the cold end portion of the framework being more corrosion resistant than the hot end portion of the framework. The cold end portion of the framework may either be made of corrosionresistant material or may be coated with a layer of corrosion-resistant material. The cold end portion of the framework K may be detachably secured to the hot end portion H. The cold end portion K may be further subdivided into sector-shaped elements (Figs. 3, 4, not shown) such that each sector may be readily replaced in the regenerator; several heating plates being combined which can be pulled out radially through the peripheral surface to check the degree of corrosion of any sector. The plates used may have a corrosion-resistant enamelled surface. Each sector has a supporting ledge 25 (Fig. 5, not shown), at the end near the hub, the hub having a corresponding recess in which the said supporting ledge may be clamped. Adjacent radial partitions of the hot end and cold end portions H and K are sealed against one another by means of sealing bars as shown in Figs. 2a, 2b or by spring plates 21 (Fig. 4, not shown). Fixed to the housing of the rotor may be a conveyer device for holding the element which is to be installed or dismantled.
