Pulverized coal injection is a method for improving the performance of a blast furnace. The PCI method is based on the simple concept of primary air (termed the "conveying gas") carrying pulverized coal which injected through a lance to the tuyere (mid-bottom in let of a blast furnace) then mixed with secondary hot air (termed the "blast") supplied through a blowpipe in the tuyere and then

Flame propagation characteristics of mixed pulverized coal
The mixed coal of different ranks was usually used in the coal gasification to improve the utilization efficiency. In this experiment mixed coal samples of different rank were prepared to reflect the real coal gasification production scenarios. 1 # mixed coal (long-flame coal anthracite = 3 1) was selected as the testing sample the specific parameters are listed in Table 2 and Table 3.
