A new coal pyrolysis model based on FLASHCHAIN model is proposed to quantitatively estimate the amount of released tar and pyrolytic gases from different kind of coals. The FLASHCHAIN model derived from the molecular structure of coal has been proposed for the rapid pyrolysis by Niksa et al. and can consider the effect of the pyrolysis condition on the products yields. The new model parameters are determined from correlation equations of improved parallel first order reaction model previously proposed by Miura et al. and the ultimate analysis of coal. The simulated results are compared with our experiments on volatile matter and tar yield with various heating rate conditions (10 and 100 K/min) and coals (Witbank, Lusca and Warkworth) The new model can predict well both yields and consider the effect of molecular structure of coal on release rate of volatile matters. The model will be applied to the mathematical mnriellinv of earhnnizatinn nrneess in the irnnmakincr nrneess
