Hope for all burner improvements
Thread Content
Today, both pulverized coal gasification and coal slurry gasification use integrated burners, but many companies still employ preheating burners and process burners for production. (The Tsinghua furnace with water-cooled walls for coal slurry already uses integrated burners.) It is hoped that such integrated burners can be promoted across the country, as this will help reduce energy consumption and waste, as well as minimize accidents. In particular, it will lower the workload on workers and shorten the time required for feeding materials. We encourage everyone to actively discuss this topic in order to bring more benefits to the coal chemical industry. . . . . . . . . . . . . . . . . .
The promotion of integrated burners across the country is beneficial, as it helps reduce energy consumption and waste, as well as the risk of accidents. In particular, it lowers the workload on workers and shortens the time required for material feeding, which is a positive development that should be promoted.
Integration mainly helps to save driving time, but more consideration must be given to safety; preheating nozzles can be damaged by high-temperature flames, and corrosion is also a factor to take into account.
I look forward to the development of technology, so that it can be widely applied: P
Furnaces with water-cooled walls have a short preheating time, allowing for immediate ignition and feeding of material. Moreover, refractory bricks have a long heat retention time. And the temperature is high. The technical requirements are very high. It’s difficult to achieve.
Both pulverized coal and water-coal slurry can be used with integrated burners; the main goal is to save time on replacing burners in the furnace. Safety also needs to be taken into account, as preheated burners can be damaged by high-temperature flames, as well as suffer from corrosion during operation. For Tsinghua’s coal-water slurry integrated burner, it is essential to pay close attention to the purging and replacement of N2 (CO2) in the central oxygen channel after the fuel gas is withdrawn. In short, integrated burners are feasible.
I look forward to technological advancements that will enable its widespread use
The burner for Tsinghua water-coal slurry is indeed convenient and simple, with low labor intensity
