CPC Subclass Not Allocatable
F23N REGULATING OR CONTROLLING COMBUSTION (control devices specially adapted for combustion apparatus in which combustion takes place in a fluidised bed of fuel or other particles F23C10/28; condition responsive controls for regulating combustion in domestic stoves with open fires for solid fuel F24B1/187)
Description
F23N covers devices and methods for regulating and controlling combustion processes in furnaces, boilers, burners, and other combustion apparatus. The classification includes fuel supply control systems, air/oxygen supply regulation, flame monitoring and safety devices, and automatic control mechanisms that adjust combustion parameters to maintain stable operation. Typical applications encompass ignition control, fuel flow modulation, excess air management, and feedback systems for industrial heating equipment. This class excludes the combustion apparatus itself (covered in F23D, F23H) and specific fuel supply systems when not integrated with combustion control (covered in F23K).
