Is there a way to chemically clean this type of exchanger from graphite impurities (tiny particles) ? is possible to chemically remove coke,soot,graphite at all? we clean it with xylene but that doesn't help
tnx
tnx
The frequency of cleaning a brazed plate heat exchanger depends on several factors, such as the type of fluid being circulated, the level of impurities in the fluid, and the operating conditions. In general, it is recommended to clean the heat exchanger at least once a year, but it may need to be done more frequently in certain applications.
The most common method for cleaning a brazed plate heat exchanger is chemical cleaning. This involves using a solution of acid or alkaline to dissolve any buildup or deposits on the plates. Another method is mechanical cleaning, where brushes or high-pressure water is used to physically scrub the plates. The best method depends on the type and severity of fouling on the plates.
No, it is important to use a cleaning solution that is compatible with the materials of the heat exchanger. Using the wrong type of solution can cause damage to the plates and compromise the integrity of the heat exchanger. It is best to consult the manufacturer or a professional for guidance on the appropriate cleaning solution.
A tell-tale sign that a brazed plate heat exchanger needs to be cleaned is a decrease in heat transfer efficiency. This can be observed through a rise in temperature or a decrease in fluid flow rate. Regular monitoring of the heat exchanger's performance can help determine when cleaning is necessary.
Yes, it is important to follow safety precautions when cleaning a brazed plate heat exchanger. This includes wearing protective gear such as gloves and goggles, ensuring proper ventilation in the cleaning area, and following the instructions on the cleaning solution carefully. It is also recommended to have a professional inspect and clean the heat exchanger to avoid any potential accidents or damage.
