Claim:
1. A fuel combustion system for burning a fuel mixture, the fuel combustion system comprising: at least one discharge nozzle and each discharge nozzle having a centrally located liquid fuel orifice and a concentric air orifice surrounding the liquid fuel orifice; a liquid fuel supply conduit being coupled to each liquid fuel orifice for supplying liquid fuel thereto from a fuel supply; an air supply conduit being coupled to each air orifice for supplying pressurized air thereto from a pressurized air source; the liquid fuel and the pressurized air only mixing with one another, upon being discharged from the respective liquid fuel and air orifices, to form a fuel mixture; a supplemental air fan for supplying supplement air to facilitate combustion of the fuel mixture; air deflector sleeve at least partially surrounding and accommodating the at least one discharge nozzle; a cylindrical blast tube surrounding the air deflector sleeve and an outlet end of the cylindrical blast tube supporting a flame retention head; the flame retention head redirecting the supplement air radially inward through a plurality of openings formed in at least one of the air deflector sleeve and a cylindrical surface of the flame retention head to assist with combustion of the fuel mixture; and the air deflector sleeve comprises an inlet section being formed of a solid surface without any openings formed therein and an outlet section having between 15 and 100 apertures formed therein, each one of the apertures in outlet section is approximately a ¼+/−⅛ of an inch in diameter, and the plurality of apertures formed in the outlet section form flow paths for the supplemental air into an internal chamber, defined within the air deflector sleeve, which assist with shaping and combustion of the fuel mixture; and a mid-section the air deflector sleeve having a diameter of between 2 and 6 inches, and a diameter of the mid-section being between 15-50% greater than a diameter of both an inlet end and an outlet end of the air deflector sleeve.
