BURNER DESIGN WITH HIGHER RATES OF FLUE GAS RECIRCULATION AND REDUCED NOx EMISSIONS

The burner used for furnaces, such as vapor decomposition. A burner is located in the 1st flame opening of a furnace, and A primary air room (26), The upper end which is a burner tube and carries out fluid 連通 at a downstream end (18) and a primary air room, And a burner tube including the burner tip which is a burner tip (20) established in the burner tube downstream end, and was turned to the 1st flame opening of a furnace so that combustion of fuel might arise in the lower stream at this tip of a burner, At least one flue gas recycle duct (76) which has the 2nd end released at the 1st end and primary air room which are located in the 2nd opening (82) of a furnace, In order to lengthen substantially the channel between the 1st flame opening and the 1st end of a flue gas recycle duct and to give the substantial barrier to a flow, the wall (95) extended in a furnace between 1 flame opening and the 1st end is included.
