DEFINITION

Classification: 431/159

(under the class definition) Apparatus including fuel discharging means mounted in a particular feeding relationship to a chamber structure the art term for which is "combustion furnace" the fuel discharging means being of the type adapted to scatter the fuel in the "furnace".

8+, for processes of flame shaping, or distributing components in a combustion zone.

115+, for combustion product return structure.

158, for means supplying fuel to a high pressure combustion chamber having a restricted outlet, and see the search notes under this subclass.

350+, for a flame holder having protective or flame enclosing structure.

SEE OR SEARCH CLASS 60, Power Plants,

722+, for a chamber in which combustion products are generated for use in a power plant.

110, Furnaces,

260+, for feeding gas or oil and solid fuel to a furnace and appropriate subclasses for furnace structure with means peculiar to the combustion of solid fuel and which may include means dispersing fluid fuel into a furnace.

122, Liquid Heaters and Vaporizers,

23+, for a closed circuit liquid heating means heated by fluid fuel.

236, Automatic Temperature and Humidity Regulation,

15+, for a furnace having a control that automatically regulates its temperature.

237, Heating Systems, appropriate subclass, for a chamber having a heating system.

239, Fluid Sprinkling, Spraying, and Diffusing, appropriate subclass for a combustion chamber nominally set forth as supporting a nozzle wherein no special relationship between a wall of the combustion chamber and the nozzle is set forth, nor any details of the combustion chamber.

266, Metallurgical Apparatus, 171+, and 200+ for metallurgical furnaces.

432, Heating,

159+, for a work heating chamber heated by combustion products generated in or fed to the work chamber and having a work holding or handling feature or structure making the device more than mere combustion apparatus.
