Waste Gas Burner

The Varec 239A Series Waste Gas Burner is designed for burning biogas generated in the anaerobic digestion process. Burning or flaring to the atmosphere reduces the potential odor nuisance from venting directly to the atmosphere. This burner is suitable for burning low volumes of biogas, which is typically very "wet", with a low BTU value (between 550 and 600 BTU and composed primarily of methane. The 239A Burner is designed to ignite the biogas by passing it through a "curtain of flame" developed by the ring-type pilot. The pilot gas mixes with air at the pilot ring, and the pilot. flame burns on lop of the ring. The biogas is deflected across the pilot flame by an integral baffle. A manually- adjustable shutter is provided at the bottom of the burner stack to change the available air volume .in case the waste gas flow rate fluctuates. Dual pilot lines in the larger models are located 180? apart to distribute the pilot flame around the entire ring. The burner pedestal is insulated internally, enclosing the pilot line(s) and the biogas line. A separable mounting base is included for pre-installation on a concrete foundation or other suitable support. A covered pilot observation and ignition port with separate inspection port are provided on the burner stack. A low-pressure natural gas pilot supply is recommended with the Varec 239A Burner. Since biogas is typically moist and dirty with fluctuating pressure and BTU value, it may not provide the reliable pilot flume necessary. Please specify if pilot gas utilized is propane.
