Commercial Test of Quicklime Injection at Masteel No.2 BF
To ensure sufficient pulverized coal combustion and reduce the fuel rate of the furnace,an analysis is made on the influence of quicklime injection on the BF working condition and production.Masteel No.2 BF undergoes a commercial test of the quicklime injection through the tuyere,and the test results show:(1)properly weakening the basicity of the stocks charged,and injecting the quicklime that has been evenly mixed with the pulverized coal at the max.quicklime injection rate of34.76kg/t,can reduce the slag generation at the furnace belly,and decrease the theoretical combustion temperature by 19℃,a figure,which is lower than that one when injecting the same rate of pulverized coal;(2)compared with the refer-ence period,the furnace runs more stably and smoothly after injecting the quicklime,and output increases and consumption reduces significantly;(3)during the second test,the proportion of injected quicklime in the pulverized coal climbs up to 3.5％with the average injection rate of4.9kg/t,the rectified fuel rate drops by 2.59kg/t and the daily output increases by 24.56t/d.
