Burnthrough of the gasifier furnace wall

The furnace wall of the gasifier is exposed to the high temperature of the process gas, leading to overheating, softening, and eventually burnout. The personnel on duty failed to detect the issue in time due to untimely inspections, which led to the accident. What should be done at this time? Ensure that the accident does not spread. What preventive measures should be taken in daily work to prevent such accidents from occurring in one’s own workplace? (To be honest, this is the first time I’ve heard of a gasification furnace’s wall being burned through, but since such cases have indeed occurred, in order to take preventive measures, I hope everyone will engage in a discussion on this topic.)

The arch roof of the vaporization furnace was burned through; there was a reaction related to temperature over a period of more than thirty minutes. The DCS system issued two alarms regarding the temperature at one point on the arch roof, but these alarms went unnoticed. A chief operator in the control room was supervising the operations along with three inexperienced individuals; it’s not clear who disabled those alarms, and the chief operator did not notice anything. To be honest, working this shift is really exhausting and depressing! I have been working on the second-phase piping system since its inception, and it gives me a great sense of achievement to see the facility being built up step by step until it operates successfully; I’ve developed feelings for this project. What happened is a huge blow to me. Apart from the defects in the furnace construction itself, I am also partly to blame, so I have decided to resign! (A man should not shed tears easily, yet I wept for the gasification furnace.)
I visited your company in September, and the on-site management there is truly excellent! I chatted a bit with the guys in the control room, and I thought they were quite skilled. Then it was your second attempt at driving and completing the process in one go; it was obvious from the phone call with Old Tang that he was very excited. Phase II was designed by the company’s own design institute, and you have already achieved such remarkable results – so what does this minor setback matter?
The burn-through of the gasifier dome occurred over a period of more than 30 minutes, with temperature changes being detected throughout that time. The DCS system issued two alarms regarding the temperature at one point on the dome, but these alarms went unnoticed. A chief operator in the control room was supervising the operations along with three inexperienced individuals; it’s not clear who dismissed those alarms, and the chief operator did not notice anything amiss. To be honest, working this shift is really exhausting, and it’s so depressing! I posted this from ... wision on 2009-12-10 20:21 [/quo Are you the class leader? ? It also appeared on the Wei River in 2007; fortunately, the personnel on site detected it in time, the outer wall turned red, and the vehicle was stopped for handling. Since then, it has been stipulated that the exterior wall temperature must be measured at regular intervals during outdoor operations.
I consider myself to be diligent and responsible in my work, yet things still went wrong; I have many thoughts on this!
Where on earth is this? Don’t just express sighs of frustration; it’s not unusual for problems to arise in the coal chemical industry. It’s essential to ensure that no one gets hurt, otherwise conscientious people will feel troubled. Unlike some leaders who push things around recklessly. Tell me what happened
Don’t think about quitting so easily; the issue lies with the lining – the arch bricks are standard, and after all these years, there must have been a problem during construction. Secondly, it is necessary to find out why and by whom the alarm was canceled; I hope you will persevere!
I also thought of a question: how should it be repaired once the vault is burned through?
Such an accident also occurred when Texaco was conducting experiments in China in the early days. According to witnesses on site, the shell of the vaporization furnace had bulged and developed bubbles; an object from the top of the furnace had been ejected, which was very dangerous. Fortunately, it was an experimental setup with low pressure levels, so no one was injured.
