Difference between air and steam atomized oil burner

Steam Atomization:

fuel oil, at the exit of the burner, is pulverized by the atomizing action of one or more jets of steam. In steam atomising burner oil is atomized by steam pressure. Steam atomizing burners possess the ability to burn almost any fuel oil, of any viscosity, at almost any temperature. For heavy oil, steam atomizing is preferred as due to reaction of steam and hydrocarbons containing large number of carbon atoms simpler substances are formed. Also that thermal advantage is obtained as steam reacts to give increased heat by preventing the escape of unconsumed products. Steam consumption for atomising oil is about one to five percent of steam produced.

Air Atomization:

fuel oil is atomized in the same way as steam atomization-the only difference is that air instead of steam is used as the atomizing agent and the oil is forced under pressure through a nozzle. Oil could be supplied to the burner either by gravity or a pump which serves to carry oil to the burner tips to overcome the resistance and play no part in atomisation. Gear pumps of positive displacement type are used to pump furnace oil. The atomizing air is supplied by blowers usually driven by electric motors and the burner could be lighted up any time.
