A new scheme for direct gasification of pulverized coal has been analyzed by a mathematical model. Gasification occurs in the annular region of a cylindrical reactor during the cocurrent flow of a steam/coal mixture, with combustion products in the reactor core region serving as an internal heat source. The model incorporates the two equation model for turbulence, mass exchange between phases due to chemical reactions and radiative heat transfer. Detailed calculations are carried out to assess the feasibility of the scheme.
