Fuel Oil Burners

The pot type of burners is the oldest type of burner. In this type, the oil is first vaporized by applying heat. The oil vapours are mixed with excess air and then burned. Oil is vaporized at a slower rate than the rate of combustion reaction. This process is modified by using atomizers to form tiny droplets of oil before its ignition. The droplets can be vaporized easily. The oil droplets produced are in the range of 0.0002 to 0.010 inch. The small size of droplets results in quick ignition and rapid flame formation. Designing of nozzle is important so that the droplets produced are delivered at uniform rate.
