Biogas-fueled combined heat and power systems are increasingly common at wastewater treatment facilities.
Recent studies indicate that the United States has more than 2,200 operating biogas power systems and has potential to add some 13,500 more. However, the use of green and sustainable biogas energy brings some often overlooked risks in the form of explosions caused by backfire: the ignition of unburned gaseous fuel in intake and exhaust manifolds, exhaust lines and downstream piping.
These backfires can have devastating effects on the engine, exhaust ducts or even buildings and personnel. Now, practical and innovative solutions can mitigate this threat by using a
