The municipal waste incineration industry requires flue valves that can withstand high temperatures and acid corrosion.
Thread Content
Experts, are there flue valves that can withstand high temperatures and acid corrosion? The flue gas temperature is 1050°C, and it contains acidic gases such as HCl and SO2; the combined volume percentage of these two gases does not exceed 1‰.
What is the diameter? 314 or 310S stainless steel butterfly valves work just fine
At such high temperatures, the main concern should be high-temperature effects; acid corrosion isn’t something that can occur without water electrolysis. That’s what I think
Detailed technical parameters are needed for this
The flue gases from waste incineration cause corrosion at high temperatures; the high temperature itself isn’t the problem – it’s the corrosion.
The main parameters are the ones listed above. Have you any experience in the waste incineration industry?
I don’t think there is any material that can withstand high temperatures and corrosion; yet some manufacturers, who may not have any knowledge of this industry, claim that such a material exists. So I was also a bit skeptical, and came to the forum to ask everyone. If such a material really exists, it would be great news for the waste incineration industry.
I haven’t had any actual experience with it, but high temperatures generally lead to oxidation or carbonization; I’ve never heard of corrosion occurring at high temperatures. It would be best to ask those who study materials about this. Also, what material are your pipes made of?
What is needed are the relevant technical parameters, such as operating temperature, operating pressure, and whether the valve is used under conditional settings or requires a sealed environment. There’s a big difference here
