Description

Technical Field

[0001] This utility model relates to the technical field of coke oven equipment, specifically to an automatic ignition device for a coke oven riser pipe. Background Technology

[0002] During the coking process, the water seal cover of the riser pipe needs to be opened at the end of the coking stage for furnace cooling. At this time, the residual raw coal gas in the carbonization chamber (containing a small amount of water vapor, tar, crude benzene and other substances) will be discharged into the atmosphere through the riser pipe, accompanied by white or yellow smoke, causing environmental pollution. In order to overcome the above drawbacks and meet the requirements of ultra-low emissions, the raw coal gas is ignited when the riser pipe is opened, which can significantly reduce the pollution of the atmosphere by the raw coal gas.

[0003] Currently, manual ignition is used during the furnace cooling process to reduce the emission of yellow and blue smoke. However, this method is not only labor-intensive and has a harsh working environment, but also poses certain safety hazards and unstable ignition. Utility Model Content
