✦ Synopsis

A numerical simulation approach is given to investigate the characteristics of coal particle ¯ow, heat transfer and combustion processes in a W-shaped furnace. In order to obtain, in detail, behaviors of coal combustion, many different coal particle sizes of two different load cases are used to predict the characteristics of combustion. The conclusions of the characteristics of coal particle trajectories, devolatilization, ignition time, ignition distance and burnout are drawn out in detail. These conclusions can be used to optimize the design and operation of the W-shaped furnace.
