Two boiler models submitted for air quality emissions testing in California have been certified as meeting certain emissions requirements. The SBW Apache boiler models in sizes 47.5 and 40 both met the stringent requirements established by the South Coast Air Quality Management District for sub 20 ppm NOX emissions. The boiler model is a two-pass refractory-back boiler model that has been used extensively in the production of ethanol at ethanol-producing facilities.
