Enclosed Combustor


Enclosed Combustors are utilized for destruction of BIOGAS vapors from Landfills and Digestors.

NAO’s first Enclosed Combustion Unit (NEC) was supplied to the city of San Francisco WWTP in 1982.

The NEC is outfitted with NAO’s Multi-Point Burner Assembly. This burner design allows the waste stream to be evenly spread across the diameter of the enclosed combustor. Our Stainless Steel burners are heavy duty castings in a variety of high temperature materials and stand up to harsh services.

Each NEC is packaged with a UL listed Control Panel and Pipe Trains. Prior to shipment each control panel / pipe train configuration is operationally tested and is usually witnessed by the end user.

NAO provides commissioning assistance, large inventory of stocked parts and supports all systems sold, by NAO.

With over 100 years of experience NAO has earned a worldwide reputation for reliability and trouble-free performance.
