Abstract
Devices and systems for transporting a material suspended in a fluid, e.g., pulverized coal, that can be assembled about a rotary element are disclosed. The devices and systems comprise a first portion or half of a fan wheel assembly, a second portion or half of a fan wheel assembly, and a plurality of splice plates for connecting the first portion of the fan wheel assembly to the second portion of the fan wheel assembly about the rotary element. Methods of manufacturing and assembling the sectionalized devices and systems are also provided.
Claims14
A method of assembling a sectionalized device for transporting a material suspended in a fluid about a rotary element, the method comprising the steps of:
- providing a split fan wheel assembly that includes a slotted area in each of a first and second portion of the fan wheel assembly;
- attaching a plurality of splice plates to the first portion of the fan wheel assembly;
- positioning said first portion of said fan wheel assembly about the rotary element;
- applying a sealant to the slotted area in said first portion of said fan wheel assembly;
- and
- attaching said second portion of said fan wheel assembly to said first portion, wherein the step of attaching the second portion of the fan wheel assembly includes aligning the first and second portions of the fan wheel assembly using multiple radially arranged alignment holes in each of the splice plates.
A method of assembling a sectionalized exhaust fan for a high-speed attrition-type pulverizer about a rotary element, the method comprising the steps of:
- providing a split fan wheel assembly that includes a slotted area in each of a first and second portion of the fan wheel assembly;
- attaching a plurality of splice plates to the first portion of the fan wheel assembly;
- positioning said first portion of said fan wheel assembly about the rotary element in the exhaust portion of the pulverizer;
- applying a sealant to the slotted area in said first portion of said fan wheel assembly;
- and
- attaching said second portion of said fan wheel assembly to said first portion, wherein the step of attaching the second portion of the fan wheel assembly includes aligning the first and second portions of the fan wheel assembly using multiple radially arranged alignment holes in each of the splice plates.
