Gypsum wet flue gas desulfurization slurry temperature casing material
Thread Content
Dear all: In engineering design, for the lime-gypsum wet flue gas desulfurization process, thermistors are used to measure the temperature of the slurry in the pipes (with a solid content of over 30%). It is difficult to determine the appropriate material for the protective sleeve; it needs to be wear-resistant as well as corrosion-resistant (its composition is complex, and it may be acidic or alkaline). Flange mounting is used for installation. I would like to ask everyone what material would be more appropriate to use under such operating conditions? Some people suggested HC, but it doesn’t meet the wear resistance requirements, and HC is too expensive overall. A reasonable and cost-effective solution is needed
These are all based on numerous mature solutions; the colleagues from the power plant can explain it to you.
We also use wet flue gas desulfurization with gypsum, but there are no temperature measurement points. Why design a temperature? For a desulfurization tower, it is sufficient to control the pH, density, and liquid level of the slurry; temperature control is not necessary

There are wear-resistant types of thermal resistors; I’ll go with those
