ALZ-heat-exchangers are used as plant components for the heating and cooling of gas streams.
The used materials can be carbon steel, various types of stainless steel and duplex materials. Therefore the heat exchangers can be used for a variety of applications. Among them are the heating of air and flue gas in power plants and waste-to-energy facilities as well as airheating in drying plants. Heat recovery from flue gas is another possible application.
As heat transfer medium usually steam, thermal oil or water are used. ALZ-heat-exchangers are customized according to the individual requirements of our customers. A variety of tube types (finned and bare tubes) are available. For smooth integration into the plants the heat exchangers can be built with different casing options. Among them are airtight casings with flanged connections to air ducts and types with enlarged tube sheets for installation into existing casings. Transition pieces for the intersection from the heat exchanger face area to existing air ducts can also be included in our scope of supply.
