Product or chemical particles on top of the heat exchanger impair the heat transfer capability of the exchanger and must be periodically cleaned to preserve high efficiency and avoid processing interruptions. It is ideal to bring a great deal of preparation into downtime and development, as suggested by professionals like The Merrick Group, Inc. Tips for Heat Exchanger Cleaning Fouling Heat exchangers may scale or foul over time. Corrosion, particles, chemical reactions, ashes, soil, etc. can be caused by fouling. Fouling results in lack of flexibility and increased costs of operation by significantly reducing the performance of the heat exchanger. Simply put, the thermal conductivity of fouling agents is typically much lower and heat transfer areas are limited. Ultra High-Pressure Jetting Because of its usefulness in extracting deposits & scales from the heat exchanger, jetting at ultrahigh pressure is the safest method of heat exchanger cleaning. The use of water alone is additionally a superior eco-sustainable cleaning process. Using ultra high pressure jetting reduces the need for toxic detergents & solvents to be disposed of. To ensure that the whole sediment is eliminated, it is crucial to keep cleaning the heat exchanger until you can easily see plain metal.. Preserving the surface like a fresh factory standard will prolong the lifespan of the heat exchanger & its performance. Fluid Temperature Water may create mineral scaling. With a rise in temperature, salts can accumulate on the surface of the heat exchanger. Similarly, biological growth will happen during food processing with a rise in temperature. Fluid Velocity At higher fluid velocities, in most cases, the fouling decreases because rising flow velocity enhances the fluid shear stress, which causes high deposit removal. Increasing the flow velocity for particulate fouling may completely eliminate fouling.
