Seeking assistance for the Puguang project: combustion status of the reaction furnace
Thread Content
At present, in the reactors of the first and second combined units, except for the viewing ports at the furnace head, black smoke can be seen inside the furnace chamber through all the other viewing ports. Please help analyze this situation. The acidic gas from Puguang contains no other impurities aside from some water and a small amount of light hydrocarbons. The quality of the acidic gas is fairly good.
Are your burners domestic-made? If there is black smoke, it’s definitely due to incomplete combustion; perhaps the burner design is inadequate. Have you put your acid gas interruption system into use? Is the combustion furnace of the device overloaded? Is the air volume insufficient?
It’s possible that the air supply volume is insufficient; let’s determine this based on the analysis data from the second stage. Is the system pressure high?
Is there no hydrogen sulfide/sulfur dioxide analyzer? I heard that there are multiple sulfur production facilities in your area.
Could you be more specific? Based on what you’ve said, it can only be roughly inferred that the hydrocarbons are not burning completely, but it’s not possible to determine what exactly causes this incomplete combustion of hydrocarbons Do you have sulfur available right now, and what is its color? ； Is the hydrogen sulfide level indicated by the analyzer normal compared to that of sulfur dioxide? How is the air distribution? ； Find out where the burners are manufactured, whether they are of the internal mixing or external mixing type, and consult the manufacturer regarding the combustion performance ； There are a series of reasons such as whether the acidic gas was analyzed before being fed into the furnace and whether its composition changed, etc. Provide some specific details; be actively involved
The burner of the sulfur production furnace is designed to burn in a low-oxygen environment; as long as the acid gas is pure and the control system is functioning properly, black smoke should not appear. It is recommended to continuously monitor the components of the acid gas feed as soon as black smoke appears, and at the same time verify whether the air-to-gas ratio is correct. It is necessary to first rule out possibilities where problems are most likely to occur, and then proceed with more in-depth investigations
All the burners used for sulfur processing at Puguang are imported, and they are extremely expensive. I guess the burners produced by Luoyang Ruichang, which are used by your Huaxing company, are even better.
