主　　题：Coal combustion 

摘      要：The global energy structure is primarily dominated by fossil fuels, with coal being the main contributor to energy supply. This article proposes a combustion method based on the combination of nonequilibrium plasma generated by medium barrier discharge and water additives. The influence of different H2O atomization rates on discharge power, mass loss, and temperature variation during plasma-assisted coal combustion processes was investigated. The research findings indicate that, under a fixed power supply voltage amplitude of 13.5 kV, as the H2O atomization rate increases from 0 to 3.0 mL/min, the asymmetry of discharge current increases while discharge power decreases. When the H2O atomization rate is 1.2 mL/min, the mass loss, temperature, and combustion surface reach their maximum values. Excessive H2O inhibits coal combustion. Compared with the case of no H2O addition, at a power supply voltage amplitude of 13.5 kV and a H2O atomization rate of 1.2 mL/min, the combustion rate of coal significantly increases, and the combustion limit is extended. © 1973-2012 IEEE.
