The fuel burner is a heating equipment that utilizes liquid fuel, wherein the fuel and air are sprayed in a specific manner through a combined combustion device.
Based on its type and application field, the combustion machine can be categorized into industrial, domestic, and specialized types.
It consists of an oil nozzle and an air regulator. The oil nozzle is positioned along the axis line of the air regulator to atomize the oil into fine droplets, which are then sprayed into the combustion chamber at a certain diffusion angle for mixing with the air supplied by the air regulator before ignition. There are primarily two types of oil nozzles: pressure atomization and dual-fluid atomization. The pressure atomizing oil nozzle comprises a splitter plate, swirl plate, and atomizing plate. As the oil rapidly rotates within the swirl plate, it is ejected through a central hole while being broken down into fine droplets due to centrifugal force; resulting in an average diameter of less than 100 microns after atomization occurs. On the other hand, dual-fluid atomizing oil nozzles employ steam or compressed air as their medium for accelerating oil breakup and subsequent atomization process. Specifically referring to Y-type oil nozzles utilizing steam as their medium for atomization; they derive their name from having oblique intersections between steam channels and oil channels shaped like “Y”. These nozzles offer advantages such as wide load adjustment range and low steam consumption.
