  • Ignition device for sintering machine
    Patent number: 4547146
    Abstract: This improved ignition device for a moving grate type sintering machine is an inexpensive, compact combustion device which can form a strip of flame extending uniformly and continuously over the width of the strand. This ignition device can provide a uniform ignition intensity, and the ignition conditions of the raw mix can be controlled optimally by moving the burner and a hood therefor vertically and/or rotatably in accordance with the operational conditions of the sintering process. The ignition device thus contributes to prevent the sintered ore from being unevenly sintered, and to save heating energy.
