How to solve it if Steam heat exchanger scaling?

- Nov 27, 2018-


The measures taken to prevent scaling include the following:


1) The steam heat exchanger is easy to clean and repair (such as plate heat exchanger);


2) After the steam heat exchanger equipment is installed, it is not necessary to disassemble the equipment when cleaning the dirt, that is, it can be cleaned at the work site;


3) The minimum dead zone and low flow rate zone should be taken;


4) The flow velocity distribution in the steam heat exchanger should be uniform to avoid a large velocity gradient and ensure uniform temperature distribution (such as baffle zone);


5) Under the premise of ensuring reasonable pressure drop and no corrosion, increasing the flow rate helps to reduce dirt;


6) The effect of the surface temperature of the steam heat exchanger on the formation of fouling should be considered.
