摘　　要：以某电厂超超临界机组为对象,通过对煤泥的4种干燥方案进行对比分析,采用蒸汽干燥技术对掺烧的煤泥进行预处理,并通过试验分析了掺烧煤泥对机组性能的影响。结果表明:在煤泥掺烧质量比为7.6%时对机组影响不大,超超临界机组煤泥干法掺烧具有可行性和经济性。Taking the ultra supercritical unit in a certain power plant as an object of study,a comparative analysis was conducted on 4 drying schemes for the slurry,among which the pretreatment way using steam to dry the slurry was adopted,while the effects of coal slurry co-firing on the unit performance were experimentally studied.Results show that when the mass ratio of slurry is 7.6%,the co-firing has little effects on the unit performance,proving the slurry drying technology to be applicable and economical in coal slurry co-firing process of ultra supercritical units.
