Thermal Oxidizer Regulation Norm
Thermal Oxidizer Regulation Norm
(OP)
Hello to all and thanks in advance for your attention,
There is a project i'm working on that requires a flexibility test to be conducted in the piping system and also in the nozzles of a incinerator, the incinerator is meant to treat tail gas (from a sulphur recovery system), which is why a termal oxidizer has been chosen. I have been looking every where for a norm that regulates maximum loads in nozzles for this kind of equipment but have failed, in first instance i thought API 560 could be used in this case, but after deeper research, i found out it can't, for example this article: http://www.zeeco.com/pdfs/zeeco-q2-2013.pdf
As you may see, i'm not experienced with thermal oxidizers, i can only think of the manufacturer providing this data for the nozzles of its equipment. If you have any info you could share that'd be great.
Kind Regards.

Also, see the Pressure Vessel Handbook by Eugene F. Megyesy for quick reference.

Edit: I guess depending on the material of the nozzle i could refer to table 5A in ASME SEC II

You may search the similar topics as discussed in the "Boiler and Pressure Vessel Engineering" forums.

"like a maximum or a rule that suggest having the stress below something,"
The allowable load is calculated according to the maximum allowable stress of the material as listed in the BPV Code. The simplified method is developed from the BPV Code. If wanted, you may search the detail references in the book for its origins of the BPV Code.

@georgeverghese (I think i'm the ignorant in this discussion, are you talking to me directly?) - In my case i'm focusing on the inlet tail gas nozzles attached to the shell, neck material SA-516-70.

@georgeverghese well from what i can see in the plans, it doesn't seem like so, would you like me to share them with you in private?
EDIT: I've checked again and yes, it seems like it is anchored to refractory brick.
EDIT 2: It seems like, the tail gas pipe connects into another pipe, which is kind of a distribution system that the equipment has to then deliver the tail gas to each of it's 3 burners, then the 3 burners are connected to the shell as the main connection, but also have anchor points to refractory bricks. It also has a "sulphur pit vent connection" which is located in the shell, I checked and seems to be anchored as noted in Edit 1, but the main connection is with the shell tho.

Yep it does look pretty thin and yeah its open to the atmosfere via a stack., so the piping where the tails gas tube is connected to the incinerator and then distributes the tails, should be modeled as part of the piping system and then have the burner nozzles checked in the interconnection with the body?
Is there a specific section of the norm in ASME VIII Div 1, that tackles problems like this? Since you mention that the loads are going to be lower than expected in a regular vessel.
