| Outline of Final Research Achievements |
To discuss the issues during low rank coal utilization, the influence of inherent moisture on the emission of inorganic elements during coal combustion was firstly investigated. This study was compared the experimental results with a particle matter (PM) generation model based on Coalescence-Fragmentation model of coal mineral by the Monte Carlo method. Further, in order to reduce volatile elements such as alkali metal vapor during air and oxy-fuel combustion of the low rank coal, it revealed absorption property of the natural kaolin and mullite particle absorbents. A pseudo-equilibrium reaction simulator developed by our group was used to evaluate the effect of air and oxy-fuel combustion condition on precipitation of lead and zinc vapor in the cooling process of exhaust gas.
