On the design of coking heating furnaces. . .
Thread Content
Since the heating furnaces in coking processes require water to be injected in order to increase the flow rate and prevent coking, the pressure in the earlier sections of the furnace tubes is higher, resulting in a slower flow rate and thus a smaller pressure drop. In the later sections, where the pressure is lower, the expansion of water vapor leads to a large pressure drop, which can affect production. I would like to ask experts how they usually solve such problems. . Thank you first. . .
This is no longer a problem. Currently, the water injection technology for coking heaters basically involves multi-point steam injection, which is generally carried out in three stages: at the inlet, in the middle section, and at one-third of the distance from the outlet.
