The design is not to allow dust escape, obviously. We have broken bag detectors to check for particles in the stream. But it is a coal processing facility and the whole facility is covered with black dust and while we aren't trying to contribute to that, a certain amount is inevitable. I have...
I have a stream of 250F wet air (wet with water not oil) downstream from the clean side of a baghouse. There is a PCV maintaining 20" w.c. on the baghouse that exhausts to atmosphere. The vendor expects the vent to atmosphere to be normally 3000 scfm with excursions up to 8000 scfm. The baghouse...
Thank you all for the input! This is very beneficial. I think I have a path forward now. Looking at Table A-1 in B31.3 Appendix A, 316L is about as good as anything at that temperature in terms of allowable stress, so I think I'll stick with that. I found a more experienced stress engineer in my...
The metallurgy matches what the furnace vendor selected for their flue gas pipe, ASTM 240 316L - which is plate. We have ASTM 312 TP316L which is pipe but has the same allowable stress derate at temperature. So I will need to go back to the vendor and see if they know something I don't. B31.3...
I am a ME with a consultant firm and I have built a few CAESAR models but still feel like every project is my first one because they have all been so different. This time I am working on a combustion gas system, and we are reusing part of the combustion gasses from the furnace to preheat sweep...
