ABSTRACT:
The present invention concerns a device sequence for burning waste oil and includes a circulating system having a pump for circulating the oil therein and a heater for heating the oil to a suitable combustion temperature during this circulation. A combustion oil system is included for diverting a portion of the circulating oil to an atomizing gun for combination therein with a source of atomizing air. The gun includes a heat exchange body portion in fluid communication with the circulating system. A linear actuator is included having a rod with a needle end that is operated by the actuator in a linear manner along the central axis of the atomizing gun for extending through the injection orifice for providing mechanical cleaning thereof and for regulating oil flow therethrough. The present invention includes a control system for regulating the operation thereof. In particular, oil is heated and circulated prior to diversion to the combustion system which also allows for pre-heating of the atomizing gun. The control system also provides for a cooling cycle after combustion is stopped wherein the oil heater and oil is circulated through the gun during the removal of residual heat from the combustion chamber that exists after heating cycle shut-down.
