The Importance of Heat Exchangers

One of the most important equipment in all industries is heat exchangers, which play the role of heat transfer in various processes. Having high efficiency in this equipment has a significant impact on increasing the efficiency of the entire production process. The formation of sticky, hard and stable deposits in facilities and equipment in contact with water is a phenomenon that limits and reduces the efficiency of these exchangers. Water-soluble compounds (in the form of ions, complex ions and single molecules) become insoluble under various conditions, such as temperature shocks, pH changes, water saturation with salts, etc., and the crystals formed on the surfaces precipitate. Since the thermal conductivity of the deposit is extremely low compared to the material of the pipes, the deposits greatly reduce the thermal efficiency of the exchanger. Among the common sediment compounds in converters, we can mention the compounds of calcium carbonate and sulfate, magnesium carbonate and sulfate, silica and silicates, etc.

Solutions to prevent the formation of deposits in the heat exchanger

Today, with the advancement of technology and according to the extensive research that has been done on the phenomenon of sedimentation in heat exchangers, researchers have achieved several methods to control the formation of sediments and remove the formed sediments. The most important solution to reduce the scale formation rate and increase the efficiency of heat exchangers is to identify the factors effective in scale formation and optimize the operating conditions of the exchanger in order to reduce the scale formation rate. Among the factors that cause scale formation in systems are the increase in TDS and EC values ​​of the fluid, temperature shocks and nucleation. Currently, the most efficient and cheapest solution to prevent scale formation is to use anti-scale and dispersant materials. However, the effectiveness of these materials is also relative and we always witness the formation of scale layers in thermal systems, and these non-conductive layers reduce the heat transfer rate and, as a result, reduce the efficiency of the exchanger. In these cases, the best and newest solution to remove sediments is suggested chemical washing of the system with a suitable sediment vector solution. Because physical sediment removal operations cause damage to equipment, waste of time and energy, and are not fully effective.
