The steam injection of the coking furnace is stopped. How to deal with the coking furnace?
Thread Content
Our company's 1.2 million tons/year delayed coking coking furnace uses three-point steam injection (3.5Pa steam) without water injection. If the steam injection suddenly stops during operation, what should the coking furnace do? Please give me guidance?
Follow the emergency shutdown procedures and cut off the fuel gas source.
Emergency shutdown to avoid coking of furnace tubes. causing accidents.
Immediately operate the indoor emergency shutdown, appropriately increase the feed volume of the heating furnace, and at the same time close the steam injection root valve on site to avoid residual oil from flowing back.；
Emergency shutdown of the furnace, rapid cooling, and timely cutting of all four connections.
If it lasts for a short time, you can slightly increase the volume and lower the furnace outlet temperature. If it lasts for a long time, consider stopping the operation. Of course, it is impossible to live without MS for a long time.
Turn off the heating furnace to cool down, inject steam from the entrance to prevent the furnace tube from coking, and treat it as a shutdown.
