Designed to cool hot, dirty flue gas streams for entry into pollution control equipment.
Air is typically the cooling medium; however, fluids can be used as well. Automatic cleaning systems can also be provided for keeping the heat transfer surfaces clean.
Applications:
A typical gas cooler is designed with the hot waste gas flowing vertically down over the outside of horizontal tubes, while cooling air passes inside the tubes. A large volume of cooling air is usually provided by multiple vane axial or panel fans mounted on the side of the cooler.
A complete system is normally supplied including tube bundles, outer shells, cooling fans, ducts, hoppers, structural supports, walkways, etc. Other cooler arrangements and orientations are also available including designs with the hot waste gas passing inside the tubes.
Tubular heat exchangers that utilize convection heat transfer to preheat combustion air or gas for the purpose of saving fuel
Complete systems comprised of a combustion chamber, control system and heat exchanger
High-temperature heat exchangers that utilize radiation heat transfer to preheat combustion air or gas for fuel savings
