Description

F23M covers the structural and functional components of combustion chambers, including refractory linings, walls, doors, and casings designed to withstand high temperatures and combustion forces. This classification encompasses internal chamber details such as firebridge structures, deflectors for controlling air and flame flow, and safety devices integrated into combustion apparatus. Inventions relating to the arrangement and protection of combustion chamber surfaces, as well as thermal and mechanical safeguards specific to combustion equipment, fall within this scope. Adjacent classes address fuel supply systems (F23D), ignition and flame stabilization (F23Q), and general furnace construction (F23L).

Scope Notes

Glossary: Air a mixture of gases containing free oxygen and able to promote or support combustion Combustion a heat-producing sequence of chemical reactions between a burnable substance and molecular oxygen, e.g. in air, in most cases generating light in the form of flames or a glow Combustion chamber COMBUSTION CHAMBERS a chamber in which fuel is burned to establish a self-supporting fire or flame and which surrounds that fire or flame Firebridge FIREBRIDGES a low wall separating the fuel bed from adjacent flue gas passages in apparatus for combustion of solid fuel, for example in reverberatory furnaces or fire-tube boilers
