Discussion on the steam injection method for the furnace tubes in delayed coking heaters?
Thread Content
The delayed coking heater can increase the flow rate of the medium in certain areas of the furnace tubes by injecting steam, which helps to reduce coking in those areas; however, this approach comes with drawbacks such as increased energy consumption and a greater amount of wastewater generated. As far as I know, some coking plants abroad do not use water injection; please discuss the various methods of water injection in coking plants, their effects, and other measures to prevent tube coking
The key is to control the injection point and flow rate; the 8th parameter is important to specify, but it is also necessary to take into account the properties of the raw material and the volume to be processed, and set values accordingly
Which foreign countries do you mean? As far as I know, the coking process carried out by FW in Huizhou also involves water injection.
Currently, multi-point steam injection is mostly used
As for whether it is better to use water or steam, there is still no definite conclusion; however, steam is currently used more often； Steam injection at three points ；
Could you please explain in detail: what does \"inject steam\" mean, what is the pressure required, and how is the injection carried out?
Let’s bring up this old topic for discussion to see if there are any ideas for saving energy in this area – could other media be used instead of steam and water? Such as dry gas or other gases and liquids
My idea is to use waste hydrogen modified with diesel as the lifting medium – is that feasible?
Most of them use multi-point steam injection! Now we start to consider energy consumption; there are those that use water for injection, as well as those that use waste gas, as you mentioned!
