Reasons for the burnout of converter burners

I’m not sure if your burner is made of metal; the ones designed by Tianyi are metal-based and can withstand temperatures of 1600 degrees. If the burner gets damaged, it’s most likely due to an inappropriate material being used, or it may be because of a lack of cooling water. The burners designed by Hua Er Yuan are made of non-metallic materials, and regardless of the material used, they all have a limited service life. They should be inspected at least twice a year. Metal burners can be repaired, while non-metallic burners can be replaced with new ones.

The burners designed by the Second Chemical Engineering Institute these days are all metal-based; non-metallic burners are hardly used any more. There are several reasons why burners can get damaged, and it depends on the specific situation. A common cause is inadequate cooling water for the burner, which leads to overheating and subsequent damage as a result of water supply interruption.

For a burner to be damaged, it must reach the temperature at which it can be damaged. 1. From a combustion perspective: the key issue is whether there are any changes in the composition of the fuel gas. For example, the combustion speed of natural gas is much slower than that of hydrogen; if hydrogen is burned using a burner designed for natural gas, it will start burning as soon as it enters the burner, which will surely cause damage to the burner. 2. From the perspective of cooling protection: whether it is air cooling or water cooling, an adequate amount of cooling medium must be ensured; otherwise, the heat cannot be dissipated, and no metal, no matter how good, can withstand such high temperatures.

On the one hand, it is necessary to pay attention to protecting the burner, including the water jacket; steam protection must not be interrupted, and I agree with what was said above. The second aspect is to pay attention to the flow rate of oxygen, ensuring a condition of mild deflagration; otherwise, the burner will remain in a backfire state and its lifespan will be short. To achieve this, it is necessary to ensure that the production load is not too low, as well as to keep the amount of water vapor mixed in with the oxygen at an appropriate level.

The protective media for the converter are desalinated water and low-pressure steam. At the beginning of operation, low-pressure steam can be introduced when the furnace temperature reaches 130–150 degrees. Uninterrupted continuous supply. To protect its operating cycle, it is necessary to maintain uninterrupted cooling. Regularly check the stability of pressure and flow rate. Especially while driving and during power outages. It requires even more careful handling. The protection medium must not be unavailable for an extended period of time. Additionally, adjust the oxygen flow rate in a timely manner; as the colleague upstairs said, it is necessary to ensure that the flame burns with a slight lack of oxygen, as backflow can also be dangerous. De-ignition can burn out the catalyst and lining. In any case, careful operation is still required. :victory:

The main reasons are an excessive amount of oxygen being supplied, too little steam mixed with the oxygen, and damage to the burner caused by improper operation of the burner’s auxiliary equipment.

Hey, it’s a problem with the operation – the coke oven gas has disappeared; only oxygen is being burned now. I’m not sure if the catalyst has been damaged.

Why is ceramic material used so little these days? Logically, ceramic materials should be the first choice for applications requiring high temperature resistance, and the problem of brittleness associated with ceramics has also been effectively addressed nowadays
