Abstract
Abstract A burner mechanism of used oil wherein the used oil of heated condition is compulsorily mixed with pressured oil, mixture of the used oil with the air is then filtered so as to convert the air voids in the mixture into finer particles, filtered mixture is then again compulsorily mixed with pressured air and is finally supplied to a burner element. The mechanism may advantageously be provided with a rotary mixed for a better mixing of air with used oil.
