It should be determined based on the required negative pressure, which is approximately 0.018 MPa.
Add a flow meter, but I personally don’t think it’s very useful for this purpose; since low-pressure steam is being used, there’s no need for it. Hehe, let’s hear what others have to say
What is the structure and working principle of the steam extractor used in starting up a water-coal slurry gasifier?
The structure consists of a constricted section of a concentric pipe, with a steam pipe located in the middle for vacuum extraction, based on the Venturi principle.
Similar to steam jet pumps, you can refer to the following
Similar to injector 1# xkjtyjm
As with all Venturi principles, negative pressure is created by generating a pressure drop. I remember doing a certain organic chemistry experiment in college where water flow was used to create suction; let me give a slightly more abstract example – it’s somewhat similar to wind.

It’s not much different from a jet pump; it uses steam injection to create negative pressure, thereby achieving the effect of pumping.
Its structure is the same as that of the injector.
