Abstract
An improved method and apparatus are described for burning gaseous or vaporizable fuels, such as kerosene or other light fuel oils or gases. The burner provides for an efficient and complete burning of the fuel in a small combustion space and at variable rates. The burner utilizes a rotating fan to form a spiral or helical air flow within the combustion chamber. An interconnected rotating fuel nozzle for spraying the fuel into the spiral air path may be used or a stationary nozzle directing the fuel toward the fan. This provides for a long residence time of the fuel and air mixture providing a complete combustion of the mixture within the relatively small volume of the combustion chamber.
Claims9
An improved oil burner comprising the combination of:
- a hollow combustion chamber having an inlet at one open end and an oulet at an opposite open end;
- a squirrel cage impeller positioned within the chamber at the inlet for drawing air into one open end of said chamber and for causing the air to move through the chamber in a helical stream;
- means for spraying the fuel oil into the stream of air adjacent to and inwardly of the impeller to form an air and fuel mixture including means for directing the fuel towards the interior walls of the chamber;
- and
- means for igniting the fuel oil and air mixture for producing a flame which passes through said chamber and out the opposite open end in a helical path.
An improved burner for liquid fuel comprising the combination of:
- a hollow combustion chamber having an inlet at one open end and an outlet at an opposite open end and being of generally ovoid shape;
- a squirrel cage impeller positioned within the chamber at the inlet for feeding air into one open end of said chamber with a generally helical path of motion;
- a nozzle mounted for rotation with said fan adjacent to and inwardly of the impeller for spraying the liquid fuel into the stream of air for directing the fuel towards the inner side walls of the chamber to form an air and fuel mixture;
- means for igniting the fuel and air mixture for producing a flame which passes through said chamber and out the opposite open end in a helical path;
- an electric drive motor including a mounting shaft for said fan and said nozzle;
- and
- a fuel conduit in said shaft communicating with said nozzle and coupled to a fuel inlet.
