Abstract
A liquid fuel combustion device that utilizes waste and contaminated oils without the need for pre-processing or filtering the fuel stock.
Claims13
A liquid fuel burner comprising:
- a plenum;
- a pre-combustion chamber housing surrounding a pre-combustion chamber, where the pre-combustion chamber housing is located within the plenum;
- a disc located within the pre-combustion chamber housing, where the disc has a first surface, an opposing second surface, an edge, and a center;
- a drive shaft extending into the plenum upon which the pre-combustion chamber housing and the disc are mounted, allowing the pre-combustion chamber housing and the disc to rotate within the plenum;
- a fuel supply tube located such that the fuel supply tube is capable of applying liquid fuel to the first surface of the disc near the center of the disc;
- and
- an igniter.

A method of combusting liquid fuel, the method comprising:
- rotating a vertical disc located within a pre-combustion chamber housing surrounding a pre-combustion chamber, where the disc has a first surface and an opposing second surface and the pre-combustion chamber housing is located within a plenum;
- applying fuel to the first surface of the disc near the center, where the fuel comprises a highly volatile portion, a less volatile portion, and a least volatile portion;
- allowing the fuel to form a thin layer of fuel with a high surface area to volume ratio on the disc;
- providing an air stream through the pre-combustion chamber, where the air stream enters the pre-combustion chamber proximate the first surface of the disc and exits the pre-combustion chamber proximate the second surface of the disc;
- allowing a highly volatile portion of the fuel to vaporize and enter the air stream;
- igniting the fuel in the air stream;
- allowing the now-hot and burning air stream to heat the second surface of the disc, which in turn heats the fuel still on the first surface, which allows the less volatile portion of the fuel to vaporize and enter the air stream;
- allowing the least volatile portion of the fuel to pyrolyze to produce carbon compound solids, which are burned in a solid state until only incombustible ash remains, which incombustible ash is swept from the pre-combustion chamber by the air stream.
