Low concentration of acidic gas in Klaus sulfur recovery; leakage from the waste boiler
Thread Content
The acidic gas enters the waste boiler through the burner; sulfur is not recovered and is sent directly to the flue gas desulfurization unit. However, the waste boiler starts to leak after operating for a while due to severe corrosion. Let’s discuss this together, everyone
Has the stay time been too long? You should inquire with the design institute or the process package supplier. Additionally, the flue gas temperature should not be below 280 degrees, as this can easily lead to the formation of acid mist.
The manufacturing quality of the waste heat boiler is one of the most important factors, including expansion jointing, welding, and lining installation; design issues and material problems may also be relevant factors.
