Our department is having a discussion.
Looking for others thoughts as to how critical Deaerator storage tank level (Spray type DA) is.
Here's the Theories:
1) Water level needs to be high enough to maintain proper NPSH to feedwaterpumps, but not above the scrubbing column. Essentially storage capacity. On/off level control ok if maintained within those ranges
2)Critical because that's where someone put the line on the tank some time ago
3) Steady operating level is critical to heat transfer and flash steam venting.
Anyone have any thoughts or other ideas?
