Have you all heard about the effect of foaming inside heat exchangers on the heat exchange area?
Thread Content
Our unit is equipped with a heat exchanger, but its heat exchange efficiency never reaches the required level. Today, an expert from the process design team came and said that the high temperature levels during operation cause the raw materials to decompose, resulting in foam forming inside the heat exchanger; this is what leads to the poor heat exchange performance. Does anyone know what’s causing this? Why do I feel like what he said doesn’t make any sense?

If bubbles do exist, this must be taken into account during the design. If you don’t explain in advance, it’s your own fault. Bubbles cause a sharp decline in heat transfer efficiency, which is quite serious.
