Pyronics® XNM Excess Air Burner
Nozzle mixing types designed for 800% excess air for single tunnel cool flame applications.
The Pyronics XNM Series Excess Air Burners for single tunnel cool flame application are nozzle mixing types designed for 800% excess air. A unique design and stepped tunnel burner blocks produce excellent flame stability at all firing rates. New air-gas mixing principles produce very high excess air combustion without appreciable fumes at lower equipment costs. All sizes develop maximum ratings with 6 oz. air pressure and 2.5 oz. gas pressure at the burners. All XNM burners have inconel flame distributors and high temperature refractory blocks. Gas adjustor and flanged connections are standard. Pipe unions are not normally required. The integral mounting flange is designed for sealed firing in positive, neutral, or negative combustion chambers.
