Grate block for a refuse combustion grate

摘要

The grate block consists of two portions, a grate block front portion (3) and a block holder (2). The grate block front portion (3), which is directly exposed to the combustion, consists of resistant materials, for example fine ceramics or chromium alloy, and the block holder (2) consists of a considerably cheaper material, for example steel or cast steel. The block holder (2), which conducts heat better, acts as a cooling body for the grate block front portion (3).
