Oil burner for boilers and the like

摘要

A motorized fan (4) is operatable to delivery an air stream through a ventilation pipe (8). A housing (12) houses a motorized sliding-vane mixer (40, 42, 44) operatable to draw air from the fan (4) and oil from an oil feeding circuit. The mixer emulsifies the oil in the air to form a homogeneous mixture and to send it to a delivery duit (62) at a relatively low pressure. A mixture-deliverying pipe (68) is housed within the ventilation pipe (8) and has an inlet end connected to the delivery duit (62) and an opposite outlet end provided with a nozzle (70) near the delivery end of the ventilation pipe (8).
