Abstract

A grate plate construction for installation as part of a grate assembly in which free flowing material is supported for movement along a path while treatment gas flows upwardly through such material. The construction has a relatively thin carrier plate having a highly wear resistant upper surface mounted in a supporting frame having ribs and webs which form with the carrier plate channels through which treatment gas flows for passage through the material via slots formed in the carrier plate by a high-energy process. The construction is economical even though the carrier plate itself is formed from relatively expensive material.
