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).
