Eclipse Tube Firing Burners are designed to fire radiant and immersion tubes with inputs from 25,000 to 2,000,000 Btu/hr. The unique nozzle design creates an intense adjustable-length flame with a vigorous spinning action. The long, spiraling flame results in cleaner combustion, efficient heat transfer and more precise, uniform tube temperatures. 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.
