摘要：Entrained flow gasification technology represents a critical advancement in the clean utilization of coal and organic waste materials. The burner, a core component of gasification systems, has historically suffered from limited operational lifespans due to issues such as erosion, thereby compromising process safety and long-term reliability. This paper proposes an intrinsically safe design principle based on the combustion/gasification reaction process and oxygen jet entrainment within the furnace, which utilizes the isolation of an inert process medium to reduce combustion intensity. Numerical simulations demonstrate that this inert process media isolation method effectively reduces combustion intensity and flame temperature near the burner exit. Based on the proposed design principle, three kinds of gasification burner isolated by coal water slurry, steam, and pulverized coal are developed and applied in industry. The industrial applications show that the service life of the newly developed burners is greatly improved compared with the traditional burner. The service life of a novel coal water slurry burner with partial coal water slurry isolation has exceeded 180 days, and the service life of pulverized coal burner with steam and pulverized coal (oxygen stream in an annular pulverized coal jet) have surpassed 490 and 360 days, respectively.
