How is the steam consumption of each stage of a three-stage steam jet vacuum pump calculated? For example, if the total steam consumption is 580KG/h, what is the corresponding steam consumption at each level? This post was last edited by chinazwr on 2009-2-5 18:52 ]
It is recommended to look at the selection of steam jet pump nozzles. The type of nozzle and operating pressure determine the flow rate of steam. The flow rate of steam determines the consumption of steam. It is generally calculated according to the calculation formula of Raoult nozzle.
Could you please explain in detail? Thanks! It would be best if you could upload the formula :lol :lol
Simple calculation company nozzle diameter (mm) = 1.57* (Gp/Pp)^1/2 units: Gp power steam consumption kg/h Pp power steam pressure barA "^1/2" refers to the root number
You are still using three-stage steam injection. If the operating cost is high, you can choose water ring + injection instead.
There are also environmental issues. In addition, if your system requires stable vacuum, steam injection is not a good choice because it is difficult to control the process.
Can you tell me how to calculate the injection coefficient?
