【 摘 要 】

The problem of particle ignition coal-water fuel (WCF) has been solved numerically, located at a high flow environment. Two different approaches to describe the physics of the process have been applied. According to the results of numerical simulation of the effect of the scale has been set about ambient temperature, the particle size on the inertia of the studied processes. A comparison of ignition delay times has been obtained using both methods of describing heat and mass transfer processes preceding fire.
