摘要：
The influences of alkaline earth metal salts (CaO, MgO) on the combustion property of pulverized coal have been studied by thermogravimetric analysis (TGA). It was indicated that CaO and MgO could improve combustion characteristics of pulverized coal. It was demonstrated that the catalysis of CaO and MgO to the pulverized coal combustion was embodied in the enhancement of the emission of volatile matters (VM) from pulverized coal, which reduced the ignition temperature. MgO exhibited remarkably higher catalytic activity than that of CaO for the combustion of fixed carbon. MgO catalytic combustion mechanism for pulverized coal was different from that of CaO.
