Background Art

[0002] The production of sintered ore mainly relies on the igniter to generate a high-temperature flame through the combustion of gas, ignite the mixed and granulated mixture of iron-containing raw materials, fuel and flux, and generate negative pressure through the main exhaust fan at the bottom to burn and finally form sintered ore; before the high-temperature flame of the igniter is generated, the gas sprayed by the igniter needs to be ignited. At present, the ignition operation is carried out by the staff holding a torch to insert the fire from the ignition port into the inside of the igniter, and then open the igniter gas valve to ignite the gas; in this process, due to the large negative pressure generated by the main exhaust fan, the torch is easy to extinguish. In actual conditions, the torch needs to be repeatedly inserted for many times to ignite the gas. If the igniter gas cannot be ignited in time after being sprayed out, it will not only affect the production progress, but also there is a safety hazard of gas leakage; therefore, an ignition device is needed, which is required to efficiently ignite the gas sprayed by the igniter, thereby ensuring the smooth operation of the sintering machine.
