Abstract
The capital and operating costs of oil burners comprising rotary air compressors are reduced by using compressors that are lubricated with the fuel oil of the burner. Preferably, the fuel oil has the qualities and flow properties of fuel oil No. 2, and the compressor does not require the peripheral equipment of self-contained lubricating systems, e.g. lube oil storage tank, cooling coils, cooling coils fan, etc.
Claims5
An oil burner adapted for burning fuel oil, the oil burner comprising:
- A. a rotary air compressor for producing atomizing air, means for lubricating the compressor with a first stream of the fuel oil;
- B. means for transferring the first stream of the fuel oil from a fuel oil source to the rotary air compressor;
- to form an atomizing air and lube oil mist
- C. means for transferring the atomizing air from the rotary air and lube oil mist compressor to a burner nozzle for mixture with a second stream of the fuel oil prior to combustion of the resulting mixture of atomizing air, lube oil mist and the second stream of the fuel oil;
- D. means for transferring said second stream of the fuel oil from a fuel oil source to the burner nozzle for mixture with the atomizing air, lube oil mist prior to combustion of the resulting mixture;
- and
- E. means for igniting the mixture of atomizing air and fuel oil.
