Shell side baffles in heat exchanger
Baffles are metal separators used in the shell side of a shell & tube heat exchangers. Baffles helping in shaping the...
An air cooled heat exchanger, or ACHE, is simply a pressure vessel which cools a circulating fluid within finned tubes by forcing ambient air over the exterior...
Finned tube heat exchangers have tubes with extended outer surface area or fins to enhance the heat transfer rate from the additional area of fins. Finned...
Before the use of cooling towers, rivers, lakes, or other cooling water supplies were required in order to meet cooling needs of power plants.
Cooling towers...
