54. Please briefly describe the consequences of scaling in heat exchange equipment.
(1) Scaling significantly reduces the heat exchange efficiency of heat exchangers, leads to increased energy consumption, and raises production costs； (2) Scaling deteriorates the heat conduction conditions of heat exchange equipment, causing the heat transfer surfaces to overheat ； (3) Scaling can cause corrosion beneath the scale, leading to equipment perforation and leakage as well as reducing the equipment’s service life. It can also disrupt the production process, affect product quality, and result in quality incidents.
It increases the heat transfer resistance of the heat exchanger, reduces the amount of heat transferred, and forces a reduction in the heat transfer area of the heat exchanger or leads to energy waste； {It reduces the flow area of the fluid, resulting in an increase in the power required for transportation} ； This leads to a reduction in heat transfer, preventing the achievement of the required process parameters, until unplanned production shutdowns occur ； Increase the cleaning workload during maintenance and extend the equipment maintenance time ； This leads to under-scale corrosion and perforations in the pipes, directly threatening the normal operation of production.
