Description

F23J covers technologies for managing exhaust gases, particulates, and residual matter generated by combustion processes, along with the flue systems that transport these byproducts. This includes dust collectors, ash removal equipment, scrubbers, and related treatment systems for both solid and gaseous combustion residues. The classification encompasses flue design, draft control, and ancillary equipment that processes or directs combustion products from furnaces, boilers, and other combustion apparatus. Related dust separation and air pollution control measures are included where integral to combustion residue management.
