Re: Activated Carbon Stored In A Silo-Preventing Dust Explosions
I think that explosion relief vents on silo's need to vent into free space. If a duct is necessary it should be as sort as possible.
The only other option is to use a vent quench unit, after checking if any extra back pressure into the silo will be generated. ■

Dear,
The concept of successfull explosin venting relies amongst others on the adequate sizing of the vent area, and the venting of pressure and flame to a safe area.
All sizing rules (e.g. NFPA 69, VDI 3673 or EN 14491) assume venting to the (open) atmosphere, or allow for the venting to the atmosphere through the use of vent ducts or flame arresting devices.
The use (and sizing for adequate strength and volume) of any downstream vessels attached to explosion vents/bursting discs is likely not documented and may require extensive full scale testing to provide evidence of safety
It should be a better/safer approach to consider the use of either a vent duct or a flame arresting device after the bursting disc...

Activated carbon stored in a silo-preventing dust explosions
I will appreciate information on the need and feasibility of connecting an expansion container to the outlet of a bursting disc installed on a silo storing activated carbon powder.
Thank you. ■
