Abstract
An improved element basket for a rotary air preheater includes a tubular structural element disposed in each of the four corners of the basket frame and extending therethrough in mutually parallel relation. During installation of the basket into the preheater rotor, rods are provided each having an attachment member formed in one end. The rods are inserted into the tubular elements and retaining clamps are attached thereto to prevent withdrawal. A chain or rope is attached to the attachment members, thus allowing the basket to be conveniently drawn into a desired position in the rotor.
Claims2
In an element basket for a rotary regenerative heat transfer device, said element basket comprising a plurality of heat transfer elements and a frame for holding said heat transfer elements;
- the improvement comprising four tubular structural elements disposed one each in four corners of said frame and extending therethrough in mutually parallel relation.
An improved method of installing an element basket in the rotor of a rotary regenerative heat transfer device, comprising the steps of:
- providing the element basket with a plurality of tubular structural elements, each providing uninterrupted passage through said element basket;
- inserting one of said rods into each of said tubular structural elements, with a distal portion of each rod projecting therefrom;
- providing a plurality of retaining clamps adapted for attachment to said rods;
- attaching one of said retaining clamps to said projecting distal portion of each of said rods, said retaining clamps preventing withdrawal of said rods from said tubular structural elements;
- providing a flexible tensionable member;
- attaching said tensionable member to said attachment members;
- and
- drawing said element basket into a desired position in said rotor by pulling on said tensionable member.
