Quench water flow rate
Thread Content
In Texaco’s water-coal slurry pressurized gasification process, a low flow rate of quench water triggers the first-level safety interlock to prevent it from entering the gasification furnace. I heard from someone recently that this water doesn’t enter the furnace, but our on-site technician said that it does enter
Interlock has been activated, but there is a bypass; it should also be LLLLL that causes the shutdown
What is the specific value of the traffic? So how was it handled during LLL?
377 LL is 188. There is no LLL
Let’s exchange ideas with each other, discuss together, and make progress as a group to figure out whether the vehicle shuts down when the flow rate is at LLL!
⑴ If the cooling water flow rate is low, the standby pump starts automatically. ⑵ If the quench water flow rate is very low, the emergency quench water valve opens. ⑶ If both quench water pumps fail, the gasifier quickly reduces its operation to half load, and the emergency quench water valve opens to supply water to the gasifier. ⑷ If the cooling water pump cannot return to normal operation in a short time, and the emergency cooling water is insufficient to meet production requirements, an application should be made to shut down the plant.
The design of each factory is different, so it’s just for reference only – don’t take it too seriously.
