A waste gas incinerator experienced a flashback with a pressure wave in the Suction Vent Gas (SVG) system. Extensive damage resulted to the SVG flame arrestor, SVG fan, SVG valves, and incinerator piping. There were no injuries. The primary cause of the incident is believed to have been a fuel rich SVG stream that was rapidly introduced into the incinerator creating a puff.' This puff' allowed flame from the natural gas ring burner to blow back into the windbox igniting the fuel rich SVG. The combustion of gas in the ducting then created a pressure wave that blew apart the flame arrestor and caused the remainder of the damage.
