Web11 apr. 2024 · Commercial dryers usually require a heat source to heat the air in order to remove moisture from the material. To achieve this, the dryer needs an efficient heat exchanger to transfer the heat. One common type of heat exchanger is the finned tube heat exchanger. A finned tube heat exchanger is made up of a group of finned tubes … WebHeat can be transferred in liquids or gases by convection. Fluids Liquids and gases are fluids because they can be made to flow. The particles in these fluids can move from …
