摘要：The effects of CaO, Fe2O3, and MnO2 on the combustion reactivity of anthracite and coal char with low combustibility were investigated using thermogravimetric analysis (TG) and a drop tube furnace (DTF) under an oxygen-rich atmosphere. TG results showed that catalysts exhibited different effects on the combustion characteristics of fuels. For ignition temperature, it was found that, with increasing addition, the ignition temperature first decreased and then increased. For combustion rate, the positive effect of the catalyst on combustion rate was significantly enhanced with the increasing amount of additive. For burnout behaviour, at an equal additive dose, the effects of the three catalysts on burnout behaviour of two fuels varied greatly. The DTF results showed that the combustion reactivity of coal char was improved even more than that of anthracite. Eventually, the effects of three factors, including properties of the catalysts, fuel properties, and combustion conditions, on the catalytic combustion, were discussed.
