摘 要：分析了多噴嘴對(duì)置式水煤漿加壓氣化爐拱頂耐火磚蝕損的主要機(jī)理，即爐內(nèi)流場(chǎng)分布規(guī)律決定了拱頂部位是耐火磚的薄弱環(huán)節(jié)，氣化爐設(shè)計(jì)尺寸、對(duì)應(yīng)操作壓力、負(fù)荷、工藝噴嘴裝配尺寸是主要影響因素。從設(shè)備、操作、管理等方面總結(jié)了避免拱頂耐火磚蝕損過(guò)快的應(yīng)對(duì)措施。目前，拱頂耐火磚累計(jì)使用周期已超過(guò)8000 h。

Abstract：The main mechanism of vault fire brick corrosion in coal-water slurry pressurized gasifier with opposed multi-burner is analyzed，i.e.，flow-field distribution pattern in the gasifier determines that vault part is the weak links of fire brick.And design dimension，relevant operating pressure，load and process burner assembling dimension of the gasifier also are the key influencing factors.The ways of settlement and c....
