The main function of the gasification burner is to transport the medium fuel (pulverized coal, coal-water slurry, tar, residual oil, etc.), oxygen, water vapor and other reaction media to the gasifier, and achieve the fog state and air flow state required by the gasification process in the high temperature and high pressure environment, so as to achieve the purpose of efficient gas production. The burner has been operating in the harsh environment of high temperature, high pressure and oxygen enrichment for a long time, and its conveying section and burner nozzle head need to have excellent high temperature resistance, oxidation resistance and anti-wear characteristics to meet the requirements of long-term continuous use. The core component of the gasification burner is the head cooling heat exchange surface, and the study of its heat exchange and stress is the key to the technology
