Abstract：Using one-dimensional flame furnace and pulverized coal ignition furnace, the blend burning tests of blue-coke mixed with Yinta carboniferous coal, Ningwuxi carboniferous coal, Zhungeer mix coal No.5 and Yangquan anthracite were carried out. The results show that, blue-coke has low volatile matter, medium-high calorific value and low ash fusibility point, it belongs to hard to fire and serious slagging coal; based on the comprehensive consideration of ignition temperature, burn-off rate and slagging characteristics, when it is mixed with Yangquan anthracite , the proportion of blue-coke is suggested to be less than 33%; When it is mixed with two kinds of carboniferous coal, the proportion of blue-coke is better to be less than 67%; when it is mixed with Zhungeer mix coal No.5, the proportion of blue-coke is appropriate to be less than 70%.
