The present disclosure is directed to an oil burning system, capable of burning various waste oils and other fuel oils, with high efficiency burn, reduced emissions, and without producing sludge within the system. Generally, the system operates by pressurizing liquid fuel to a ultra-high pressure and delivering the fuel through a two-stage filtration system, pre-heating the fuel, dispensing the fuel through a nozzle and igniting the fuel.

1. An apparatus for increasing the efficiency of an oil burning system, comprising: a pump having a pump inlet and a pump outlet, the pump inlet in fluid communication with a source of oil based fuel, said pump for receiving the oil based fuel at the pump inlet at a first pressure and discharging the oil based fuel through the pump outlet at a second pressure higher than the first pressure, wherein the second pressure is at least 200 psi;an accumulator having an accumulator inlet in fluid communication with the pump outlet and an accumulator outlet, said accumulator for absorbing pulsations in the oil based fuel discharged by said pump;a pre-heater having a pre-heater inlet in fluid communication with the accumulator outlet and a pre-heater outlet, said pre-heater for heating the oil based fuel to one or both of a desired temperature and a desired viscosity; andan oil burner nozzle in fluid communication with the pre-heater outlet for receiving and atomizing the oil based fuel and delivering the oil based fuel to a burner. 2. The apparatus of claim 1, wherein the burner is the burner of an associated boiler. 3. The apparatus of claim 1, wherein the oil burning system is a home heating system. 4. The apparatus of claim 1, wherein the second pressure is in the range of 200 to 3,200 psi. 5. The apparatus of claim 4, wherein the second pressure is in the range of 1000 to 2,200 psi. 6. The apparatus of claim 1, further comprising: a first valve having a first valve inlet in fluid communication with the pre-heater outlet and a first valve outlet in fluid communication with said oil burner nozzle, said first valve for selectively controlling a flow of the oil based fuel to said oil burner nozzle. 7. The apparatus of claim 6, further comprising: a first filter assembly inlet in fluid communication with the pre-heater outlet, a first filter assembly outlet in fluid communication with the first valve inlet, and one or more filter elements for removing impurities from the oil based fuel. 8. The apparatus of claim 7, further comprising: a second filter in fluid communication with said pump and said pre-heater. 9. The apparatus of claim 1, further comprising: a variable pressure control for controlling operation of the pump responsive to changes in an exhaust stack temperature. 10. The apparatus of claim 9, further comprising: said variable pressure control operable to control operation of the pump to decrease the second pressure when the exhaust stack temperature is above a pre-selected value. 11. The apparatus of claim 10, further comprising: said variable pressure control operable to control operation of the pump to increase the second pressure when the exhaust stack temperature falls below the pre-selected value. 12. The apparatus of claim 10, wherein said preselected temperature is in the range of 370-410 degrees Fahrenheit. 13. The apparatus of claim 10, wherein the first valve is in electrical communication with the variable control to regulate the distribution of fuel from the oil burner nozzle. 14. The apparatus of claim 1, wherein the oil based fuel is selected from the group consisting of number two home heating oil, waste oil, and combinations thereof. 15. The apparatus of claim 14, wherein the waste oil is selected from the group consisting of biofuel, light grease, waste and virgin paint solvents, waste and virgin cleaning solvents, diesel, kerosene and hydraulic oils. 16. The apparatus of claim 14, wherein the amount of waste oil does not comprise more than fifty percent of the overall composition of the oil based fuel. 17. An oil burning system comprising: a storage device for housing a quantity of oil based fuel for use within the system; anda distribution system, wherein the distribution system is disposed to deliver the oil based fuel to a burner, said distribution system comprising:a pump having a pump inlet and a pump outlet, the pump inlet in fluid communication with an outlet of said storage device, said pump for receiving the oil based fuel at the pump inlet at a first pressure and discharging the oil based fuel through the pump outlet at a second pressure higher than the first pressure, wherein the second pressure is at least 200 psi;an accumulator having an accumulator inlet in fluid communication with the pump outlet and an accumulator outlet, said accumulator for absorbing pulsations in the oil based fuel discharged by said pump;a pre-heater having a pre-heater inlet in fluid communication with the accumulator outlet and a pre-heater outlet, said pre-heater for heating the oil based fuel to one or both of a desired temperature and a desired viscosity; andan oil burner nozzle in fluid communication with the pre-heater outlet for receiving and atomizing the oil based fuel and delivering the oil based fuel to the burner. 18. A method for improving the efficiency of an oil burning system of a type having a storage device housing a quantity of an oil based fuel, a burner, and a distribution system for delivering the oil based fuel to the burner, said method comprising: pressurizing the oil based fuel using a pump having a pump inlet and a pump outlet, the pump inlet in fluid communication with the storage device, the pump receiving the oil based fuel at the pump inlet at a first pressure and discharging the oil based fuel through the pump outlet at a second pressure higher than the first pressure, wherein the second pressure is at least 200 psi;delivering the oil based fuel at the second pressure from the pump to an accumulator to absorb pressure fluctuations in the oil based fuel;pre-heating the oil based fuel exiting the accumulator to produce a flow of pre-heated oil based fuel having a steady, elevated pressure;delivering the flow of pre-heated oil based fuel to an oil burner nozzle associated with the burner; andatomizing the flow of pre-heated oil based fuel with the oil burner nozzle. 19. The method of claim 18, further comprising: monitoring an exhaust stack temperature of the oil burning system; andif the exhaust stack temperature is above a preselected temperature, controlling operation of the pump to decrease the second pressure. 20. The method of claim 19, further comprising: if the exhaust stack temperature falls below the preselected temperature, controlling operation of the pump to increase the second pressure. 21. The method of claim 19, wherein the preselected temperature is between 370-410 degrees Fahrenheit.
