Please help to make the deflagration venting size calculation!

[foresthills]

Hi,

I have to calculate the venting size for an enclosure which houses a sugar pulverizer. The enclosure is reinforced concrete. The problem is the venting must be led to the outside of another big building through a long duct. The duct will be about 6m long. According to NFPA68, the venting size calculated could be as high as 23 sq.m. That's not practical.

Could you please tell me if there are any other measures to solve the problem? Is it acceptable to install the rupture diaphram or venting panel at the top of the venting duct so that we will not need to correct the reduced pressure Pred?

Thank you.

Send me your e-mail address. I can give you some guidelines. The size is NFPA code driven depending on the size, quantity and use of facility. Send e-mail to LM_1959@hotmail.com

Good luck
