Abstract
PURPOSE:To reduce the generation of NOx by installing a disc-shaped burner head where gas nozzles and primary air nozzles are concentrically installed in centering a secondary air nozzle at the opening edge of the cylindrical body of a burner in the entitled burner used for a continuous annealing furnace, etc. CONSTITUTION:Gas passing through a gas supply port and a gas lance 5 and ejected from a gas nozzle 7 carries out primary combustion F1 together with air passing through an air supply port and an air chamber and ejected from a primary air nozzle 39. On the other hand, air ejected from a secondary air nozzle 12 carries out secondary combustion F2 together with the unburnt gas in the combustion F1. At this time, since a plurality of primary air nozzles 39 are the same in shape and located at equal distances from the gas nozzles 7 and the ejected air amount is uniform, uniform combustion can therefore be obtained in the circumferential direction of a burner head surface 30. By this constitution, the amount of NOx generated can be reduced.
