Abstract: PURPOSE:To stabilize the conditions of a blast furnace without forming extraneous matter in the furnace by a method wherein exhaust gas from an air heating furnace is mixed into a blast for the blast furnace in the case when production is curtailed by lowering the quantity of the blast, and bosh gas is ensured. CONSTITUTION:An exhaust gas duct 5 branched from a flue 7 of an air heating furnace 2 is connected to a blast pipe 4 through a pump 9, a buffer tank 8 and a pump 9', and the flow rate of exhaust gas flowing through the duct 5 is controlled by means of a controller 10.

CONSTITUTION:Ignition small holes 7 have a larger cross sectional area than the other small holes 3, and flame sensing small holes 9 also have a larger cross sectional area than those of other small holes 9. A high voltage is applied to between an igniter 6 and a burner head 1, a spark discharging is carried out at the ignition small holes 7 to ignite premixed gas, resulting a spreading a flame. The premixed gas injected from the openings of the metallic net 2 may form a flame with the openings being applies as its flame ports. However, since the metallic net 2 and a burner head 1 are contacted with each other at their points, less thermal conduction is found, the metallic net 2 is heated up to its hot temperature condition to form a stable flame. In order to resistrict nitrogen oxide from being generated, a surface area of the burner head 1 is made wide, several small holes 3 are formed to decrease a density of combustion and further to decrease a flame temperatue. Flame sensing small holes 9 which are larger than the small holes 3 are made, resulting in that it is possible to get a higher electric current than that found at the other combustion portions and to facilitate a sensing of the flame.
