Gasification is an important means to realize clean and effective coal conversion.C-H-O-S-N thermodynamic equilibrium systems on coal gasification are computed in this paper,based on which a new method of two-stage coal gasification with the auxiliary of plasma torch is proposed.Analysis results show that higher output per unit volume of gasification furnaces can be obtained in this method than in general methods because the gasification speed is highly increased from several aspects under plasma conditions.In addition,this method has advantages in economical and environmental benefits compared with general methods.
