Nozzle mix burner AC series

regenerativenatural gasdirect fired

FEATURES •precise adjustment of flame formation by automatic control valves for each nozzle in the skid units •manual control of mixing impulse from outside without nozzle replacement •lowest NOx formation due to no interior equipment •automatic adjustment of burners after change of gas quantity, e.g. after job changes •for underport installation at cross fired and end fired furnaces •for natural gas, LPG air mixture or biogas GENERAL The HORN DUALFLAME AC gas burner is installed as an underport burner in cross fired or end fired regenerative furnaces. Its design enables the furnace operator to adjust the flame formation smoothly within a wide range – from short and sharp to long and soft – by using two separate gas nozzles in one burner. The gas quantity flow in each nozzle can be controlled automatically by additional gas control valves in the burner gas supply stations. Thus the flame can be adjusted to achieve optimum results in terms of flame length, energy and NOx emission. DESCRIPTION As is the case with the DUALFLAME MC burner, the AC burner works with two nozzles, an inner and an outer nozzle. The position of the inner nozzle can be controlled by a hand wheel at the rear of the burner in the same way as the DUALFLAME MC. Thus the flame can be shaped from soft and wide to sharp and strong.
