摘　　要：提出了一种适合高炉喷煤高浓度输送的新工艺，即采用喷粉罐底部流化，上部出料，总管输送，补气调节，炉前分配器分配方案，固气比可达５０～１００ｋｇ／ｍ３（粉／气）．该工艺对高炉大煤量喷吹有重要的实用价值．A new technology of high density transport for coal injection into blast furnace is presented in this paper.Pulverized coal is discharged through a single pipeon the upper part of a fluidized-bed tank, distributed to tuyeres witha distributor in front of the blast furnace, and the injection rate can be adjusted by means of supplementing gas. High solid gas ratio about 50～100 kg/m 3(solid/gas) is achieved with rather even distribution of pulverized coal.
