Description

F27D covers structural components, functional elements, and auxiliary devices that are applicable across multiple types of furnaces, kilns, ovens, and retorts. This includes features such as refractory linings, insulation systems, hearths, grates, burners, air supply mechanisms, temperature control devices, and structural supports that are not specific to a single furnace type. Details specific to particular furnace categories (e.g., blast furnace components used only in blast furnaces) are classified in the relevant specialized subclasses instead. This subclass serves as a repository for multi-purpose furnace accessories and shared technical solutions that enhance efficiency, durability, or operational capability across diverse high-temperature processing equipment.
