摘 要:簡要介紹了多噴嘴對置式水煤漿加壓氣化爐燃燒室內(nèi)襯耐火材料的結(jié)構(gòu)和選用原則,分析了耐火磚的蝕損機(jī)理、燒蝕模式及影響耐火磚使用壽命的因素,對提高耐火磚使用壽命的措施進(jìn)行了探討。目前,氣化爐拱頂耐火磚使用壽命已突破15000h,且仍有延長空間,耐火磚的蝕損速率明顯降低,為氣化系統(tǒng)的長周期、安全、穩(wěn)定、高效運(yùn)行奠定了基礎(chǔ)。

Abstract:A brief introduction is given to the structure and selection principles of lining refractory materials for combustion chamber in the multi-nozzle opposed coal-water slurry pressurized gasifier,an analysis is done of the erosion damage mechanism of refractory bricks,ablation mode and factors influencing the service life of refractory bricks,and an investigation is carded out on measures for prolonging the service life of the refractory bricks.Currently,the service life of refractory bricks at the arch of the gasifier is over 15000 h,and there ....
