It’s difficult to lift after the semi-dealkalinity decreases
Thread Content
In recent days, the total alkalinity of the semi-dealkalized solution has been dropping continuously. A large amount of alkali is being added at present, but there is no significant increase in alkalinity. I would appreciate some advice from those with more experience Thank you! :handshake
What about the other components of the desulfurization solution? Check your regeneration status; it might be caused by an excessive number of rich reactions.
Your situation is as follows: the total alkalinity is decreasing, the desulfurization efficiency is low, and the hydrogen sulfide level at the outlet is even higher than before? Otherwise, explain your situation in more detail – what are the components? It is necessary to clarify whether there has been any change in the type of coal.
Thank you! The regeneration is not working well; however, after cleaning the injector and nozzle and increasing the air intake volume, the situation has improved significantly. :handshake
Thank you! The cause of the problem has been largely identified: the amount of recycled air is too low, which results in poor performance and higher levels of by-products.
