Control of the opening angle of the automatic flap
Thread Content
In the “normal” production of coking, what is an appropriate level of control over the opening degree of the automatic flap valves in the systems for returning furnace gas and raw gas? In my opinion, an opening degree of around 40–60% is sufficient; this provides some margin for adjustment in case of fluctuations in flow rate. I’m not sure what the control standards are for others – please share them if you know. Thank you
I think it can be set to full, but not completely off; so 20%~100% should work
So big? Isn’t it already an abnormal setting when it’s turned all the way on? ! Or it could be said that some abnormal factor has already appeared
It’s best to leave some room for adjustment in case of emergencies
It can’t be turned all the way on, right? If it is, then it can’t be adjusted. Usually, during peak production times, it’s only operated at around 80% capacity. I wasn’t in the factory for very long, so I’m not sure if it’s designed to be turned all the way on.
It is generally between 30-70%; when there are large fluctuations, the valve of the preheater is used for control.
