F23H

GRATES (inlets for fluidisation air for fluidised bed combustion apparatus F23C10/20); CLEANING OR RAKING GRATES

Description

F23H covers mechanical grates used in combustion apparatus and devices for their maintenance. This classification encompasses fixed and moving grates designed to support fuel in furnaces, boilers, and fireplaces, as well as mechanisms for cleaning, raking, or removing ash and clinker from grate surfaces during operation. The scope includes grate constructions, support structures, and powered or manual cleaning systems integrated with or retrofitted to combustion equipment. Related combustion apparatus classifications (such as F23B for furnace structures) are distinguished by their focus on the overall combustion chamber rather than the grate element itself.
