Alfa Laval is the only supplier on the market with more than a half-century of experience with spiral technology. Today our spiral heat exchangers can be found in plants around the world, solving tough problems in industries that include:petrochemical, refinery, steel making, pulp and paper, mineral processing (metals, ore), wastewater treatment (municipal and industrial), pharmaceutical
4 Alfa Laval spiral heat exchangers Alfa Laval spiral heat exchangers (SHEs) are based on an ingen-ious design. It provides optimum heat transfer and flow conditions for a wide variety of fluids, with a built-in self-cleaning effect, while keeping the overall size of the unit to a minimum. Self-cleaning design High thermal efficiency
Experimental and CFD investigation of spiral tube heat Jan 01, 2021 · 3. Experimental & CFD investigation of spiral heat exchanger. In this spiral coil heat exchanger hot fluid is on the tube side and cold fluid is on the shell side. To find heat exchanger efficiency, it has to be tested in various flow conditions such as varying flow rates. In this case, the heat exchanger was analyzed at 5 different flow rates
Spiral plate heat exchangers are widely used in various industries due to their advantages such as their simple structure, high heat transfer efficiency, low maintenance costs, smaller occupied area, and etc. These kinds of heat exchangers are made by rolling long metallic sheets in two different passages.
SONDEX® Spiral heat exchangers DanfossDesigned and custom made to handle sludges, slurries, waste water, wood pulps, hydrocarbons with high viscosity, and fouling liquids that contain fibers and solids, our SONDEX ® spiral heat exchangers are the ultimate solution for even the most challenging, high-viscosity media. Since we use coiled metal sheets instead of tube bundles, we can achieve very high thermal performance without sacrificing the
These thicker liquids cause a lot more grime and clogs, which is why the spiral heat exchanger has been built to clean itself to a certain extent. The single-flow path and rotary current creates a self cleaning effect that initiates a low pressure drop and allows the spiral heat exchanger to easily dislodge blockages. Therefore, even though one would expect it to get dirtier and be harder to clean, the spiral heat exchanger
The spiral heat exchanger - a higher overall heat transfer
Design method and software development for the spiral Feb 05, 2020 · The spiral wound heat exchanger (SWHE) is a kind of shell and tube heat exchanger. It is widely used in liquefied natural gas plants, air separation plants, petrochemical enterprises, rectisol, nuclear power stations due to their advantages of highly compact structure, good thermal compensation performance and high-pressure endurance  ,  .
May 21, 2018 · API Standard 660 Shell and Tube Heat Exchangers for General Refinery (9th Edition, March 2015) This standard specifies requirements and gives recommendations for the mechanical design, material selection, fabrication, inspection, testing, and preparation for shipment of shell-and-tube heat exchangers for the petroleum, petrochemical, and natural gas industries.
Spiral Wound Tube Heat Exchanger, innovated high efficient Spiral Wound Tube Heat Exchanger make new inovation on Tube Side. By development of Spiral Wound Tube bundle, which could create strong turlulent flow in tube side. It greatly improves the efficiency of thermal transfer, 3~7 times higher than conventional Tube and Shell Heat Exchanger. The Max. heat transfer coefficient could reach 14000W/.
