Abstract
A reversible, wear-resistant ash screw cooler section is provided with a carbon steel inner liner having a high chrome, high carbide overlay emplaced thereon to improve its wear and erosion resistance. To facilitate obtaining the maximum wear out of the section, the replaceable section is made symmetrical about its vertical and longitudinal centerline and provided with suitable compatible flanges and symmetrically placed cooling water hookups on the ends of the section to allow the section to be reversed, end for end, and reconnected to the ash screw cooler.
