Patent ID: 8052418

Claim:
An oil burning system comprising: a storage device for housing a quantity of oil based fuel for use within the system; and a 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; 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; an 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; and a variable pressure control for controlling operation of the pump responsive to changes in an exhaust stack temperature, 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.
