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.
