Heat Exchanger Fouling
Fouling is defined as the formation of undesired deposits on heat transfer surfaces, which increase the resistance to fluid flow, resulting in higher pressure drop and reduced heat transfer. The growth of deposits causes the thermohydraulic performance of heat exchanger to degrade over time. Fouling affects the energy consumption and therefore increases the amount of extra material or fuel required to generate the required amount of heat transfer.

Hi all,
ReplyDeleteFouling of heat exchangers in processing industries is a chronic operating problem. Costs due to over-design, additional fuel consumption and maintenance, loss of production, etc. These have been estimated as 0.25% of the GNP of industrialised countries. In addition to the appropriate selection of operating conditions and exchanger geometry, there are numerous chemical and mechanical methods to mitigate fouling and to remove deposits from the heat transfer surfaces. Thanks a lot.....
