The ground state geometrical of cyclic sulfur molecules S8 has been studied with RHF/6-311G* of ab initio methods. Gibbs free energy of CO, SO2, S8 and CO2 from 300 to 1673K has been calculated using ab initio method. Besides, the reaction free enthalpies were calculated. The results show that resultants of reaction of CO and SO2 are S8 and CO2 below 1451K and the reaction is spontaneous.Fe2O3 in glass can is reduced into FeO whose redox number is negative. The Gibbs free energy of FeO is smaller than that of FeS while chemical stability of FeO is higher than that of FeS. Structures of cycle sulfur are versatile. Bond energy of S8, S12 and S18 is broken, which need high energy. When small sulfur ring molecules be formed, the chemical and heat stability of S8 are improved.

In this paper, red mud of aluminum industrial residue has been studied to make the glass-ceramic, quartz sand, magnesite, fluorite and red mud was mixed to melt, molten glass was poured into the model in shape, then annealing, glass-ceramic was make, the color of glass-ceramic is brown or black, the crystals in glass-ceramic body is iron oxide by XRD, Strength, the expansion coefficient and morphology of the sample were measured. Glass surface color depends on the melting temperature.

In this paper, the mathematical models of gas dynamics, combustion and heat transfer and dispersed phase were established for the glass furnace combustion space, according to the practical glass furnace and operation condition, the computer simulation of the glass furnace was made; the simulation results coincided with the facts. On the base the influence of particle size of petroleum coke and oxygen-enriched combustion on the furnace combustion has been simulated.
