Abstract
Identifying the difference of ignition delay time between bituminous and lignite coals is the main aim of this research. Finding the reaction mechanisms affecting this behaviour is a key part of the investigation. Seven reaction mechanisms are used to represent coal combustion at a particle level, and this paper principally focuses on the devolatilzation process reaction for predicting the ignition delay time of coal particle combustion. Two types of coal namely PSOC 1451 and PSOC 1443 are examined numerically, and results are compared with the experimental data. Existing kinetic parameters for the devolatilization reaction R1 (Coal -> Coalvolatile + char) underestimates the ignition delay time which is largely influenced by the value of the pre-exponent factor (A) of R1. Results giving the best agreement with the experiment are obtained with A= 3.12 x 105 and 9.36 x 107 for PSOC 1451 and PSOC 1443, respectively.
