FEEDING FUEL TO COMBUSTION APPARATUS

Description

F23K covers fuel supply systems and mechanisms for delivering solid, liquid, or gaseous fuels into combustion chambers of furnaces, boilers, engines, and similar equipment. This subclass includes fuel feeding devices such as injectors, burners, stokers, and fuel metering systems, as well as related control and regulation mechanisms for managing fuel flow rates and distribution. The classification excludes fuel preparation and treatment processes (covered under F23D) and focuses specifically on the mechanical and functional aspects of fuel introduction into the combustion zone.
