FEATURES •smooth adjustment of flame formation by different air and oil nozzles •suitable for Heavy oil or Light oil •oil atomizing with compressed air or natural gas •low NOx formation •for underport installation at cross fired and end fired furnaces or as air casing burner GENERAL The HORN MOB burner for oil is installed as an underport burner in cross fired or end fired regenerative furnaces. The burner is able to operate with different types and quality of oil available in different areas of the world. Its design is characterized by two burner nozzles, one for oil and one for compressed air. It enables the furnace operator to adjust the flame formation in two ways: the dimension of the oil nozzle and the dimension of the air nozzle. DESCRIPTION The HORN oil burner MOB allows the furnace operator to adjust the flame shape by the dimension of the two available nozzles – one for oil and one for compressed air. Air nozzle The air nozzle cross-section has to be designed according to the available oil viscosity, the atomizing compressed air pressure and the desired flame length on site. Depending on the oil viscosity and the desired sharpness of the flame, the atomizing air consumption is between 0,2 – 0,5 Nm³/kg fuel. The available air pressure should have about 2,5 – 3,5 bar.
