Waste oil multi-fuel fired burner

An apparatus for the combustion of liquid fuels, including high-viscosity and waste oils comprising:

• a. A pressurized fuel delivery mechanism;
• b. One or more oil preheaters located within one or more preheater blocks into which pressurized fuel for combustion flows from an outside source past one or more heating elements which do not produce heat until the burner calls for heat;
• c. One or more oil pressure gauges through which pressurized fuel for combustion flows before entering said oil preheater;
• d. One or more oil regulators through which pressurized fuel for combustion flows before entering said oil preheater;
• e. One or more normally closed oil solenoids or valves that are opened when the burner calls for heat through which pressurized fuel flows before entering said oil preheater;
• f. One or more cumulative air tanks that accept pressurized air from an outside source and gradually feeds the pressurized air into one or more air preheaters located within one or more preheater blocks;
• g. one or more cumulative air tanks that accept air from an outside source through one or more normally closed air solenoids or valves that are opened when the burner calls for heat;
• h. One or more cumulative air tanks that accept air from an outside source through one or more normally closed air solenoids or valves that are opened when the burner calls for heat and are energized when the burner cycles off such that residual air in the cumulative tank blows out any residual oil left in the nozzle assembly, thereby minimizing unintended post-flame oil discharge from the nozzle;
• i. One or more adjustable air regulators through which the compressed air from an outside source can be regulated and adjusted as it enters the one or more cumulative air tanks;
• j. One or more air pressure gauges between the one or more cumulative air tanks and the air preheater;
• k. One or more air preheaters into which pressurized air for combustion flows past one or more air heating elements, at least one of which elements is warm at all times and one or more elements which are not heated until the burner calls for heat;
• l. A series of one or more heat conductive members connecting one or more of the air preheater elements with the external surface of the preheater;
• m. One or more nozzles through which the preheated, pressurized oil and preheated pressurized air are transported, mixed and atomized into microscopic droplets of aerated oil;
• n. One or more ignition devices in close proximity to the output end of the one or more atomization nozzles, capable of igniting the atomized fuel as it exits each nozzle.
