水煤浆气化炉烧嘴改造与应用

Modification and application of coal-water slurry gasifier burner

在深入研究气化炉工况和实验室研究的基础上,开发了适应新型气化炉的预膜、外混式三通道水煤浆气化工艺烧嘴,通过多项技术控制手段增强了烧嘴出口煤浆的雾化效果,同时,对烧嘴各通道安装尺寸、烧嘴保护方式、环隙氧量操作比例等进行改造,优化了气化烧嘴的性能和结构,形成了延长气化烧嘴使用寿命的关键技术。

Exploiting three channels coal water slurry gasification process burner with pre-film and mixed type which adapts new gasifier on the basis of gasifier conditions research deeply and laboratory studies. Enhancing atomization effect of coal slurry at burner exit by means of a number of technical control, at the same time, transforming mounting dimension of each channel burner, protected mode of burner, operating ratio of oxygen ring gap, optimizing performance and structure of gasification burner, forming a key technology in extending gasification burner life.
