Eclipse low emissions TFB burners are designed to fire radiant and immersion tubes with inputs from 300,000 to 2,000,000 Btu/hr. With a vigorous spinning action, the unique nozzle design creates an intense adjustable length flame. This long, spiraling flame results in cleaner combustion, efficient heat transfer and more precise, uniform tube temperatures. In addition, the flame scrubs the inside of the fire tubes to remove the gas film boundary layer and increase heat-transfer effectiveness with outstanding temperature uniformity. Not only do these factors contribute to longer tube life, they also ensure consistent uniform process heating.
