Reversible, wear-resistant ash screw cooler section

A replaceable, wear-resistant ash screw cooler section for the feed end of an ash screw cooler, comprising:

• a U-shaped, carbon steel liner plate having a pair of identical, outwardly facing flanges at each end of the U and a high chrome, high carbide overlay emplaced on an inner surface of the liner plate;
• a U-shaped, carbon steel trough jacket partially surrounding an outer surface of the U-shaped liner plate and welded along a lateral edge of the trough jacket to the liner plate to partially define a water jacket therebetween which has a first and a second end;
• a pair of flanged plates, one welded at each end of the water jacket, which, together with the U-shaped liner plate and the trough jacket serve to completely define the water jacket;
• and
• a plurality of cooling water hookups symmetrically located on the trough jacket near the ends of the ash screw cooler section, for providing cooling water to and from the water jacket.
