NAO Airocool™ and Hydrocool™ Burners are unique inspirating type burners that fire a wide range of gaseous fuels and waste vapors. These burners have special nozzles to produce either narrow (pencil type) or wide flames.
The burners are available in sizes from 1/2", 1", 1 1/4", 2" to 8" diameter with firing rates of 50,000 to 8 MM Btu/Hr. The burner venturi is highly effective in inspirating air, producing a cool low NOx flame. The burners operate with very low excess air and provide well defined and stable flames. These burners have been in service for over 70 years and are very reliable and easy to operate. These burners are very heavy duty and will operate many years (many units in service for over 30 years) without repairs or replacement parts.
For example, in Ecuador, a refinery had Airocool™ Burners in service for over 30 years and then were "sold" some new high efficiency low NOx Brand "X" burners. The Brand "X" burners were put into service and performed poorly -- the Brand "X" were sold as low NOx type but their NOx levels were actually much higher (nearly 2x) that the old Airocool™ Burners. After 2 years of trouble, replacing tips every few months and plugging of the very small burner orifices, the refinery people contacted NAO to get new Airocool™ Burners to replace the Brand "X" burners. Since the Airocool™ Burners were reinstalled the refinery has operated trouble free for almost 5 years and the operators are happy again.
The Airocool™ Burners are available in single, dual (see below for dual -- RAMS HORN DESIGN) and 4 headed configurations for straight and angle firing.
Hydrocool™ Burners are used when the plant or waste gas contains high percentages of hydrogen (very fast burning gas). The Hydrocool™ Burners use a special venturi insert in the burner nozzle to accelerate the gas at its exit thus reducing flashback of the fast burning hydrogen gas.
The Airocool™ burners can also be equipped to fire oil (#2 or even heavy oils, i.e., bunker C) as a backup.
The Airocool™ Burners can also be supplied with primary eductors for low pressure vapors or waste gases. The eductor will pull the waste vapor or gas into the burner. They produce a vacuum of approximately 6" (150 mm) WC and are driven by compressed air, steam or fuel gas.
