Quantum chemistry calculation and experimental study on coal ash fusion characteristics of blend coal
配煤对煤灰熔融特性影响的实验与量化研究

The coal ash fusion characteristics of high fusibility coal blending with two low fusibility coals respectively were studied.The data were analyzed using quantum chemistry methods and experiment from micro-and macro-molecular structures.The results show that Ca2+,as the electron acceptor,easily enters into the lattice of mullite,causing a transition from mullite to anorthite.Mullite is much more stable than anorthite.Ca2+ of anorthite occupies the larger cavities with the SiO4]4-tetrahedral or AlO4]5-tetr...
