A friend asked me this. I remember doing one for a sugar beet pulp conveyor, bit just plowed off a bit of the product into a pan of water.
"Some years ago there was a fire suppression system for (saw)dust conveying ducts that used an IR sensor along with high pressure spray nozzles fitted down stream. A spark that was detected was sprayed with water and suppressed, preventing a dust explosion in the filter bag house. Could you ask the assembled multitude if anyone remembers the maker?" -- Ed Vining 4819 John Muir Rd Martinez CA 94553 925-228-8792 _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [EMAIL PROTECTED] To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field)
