抄録

Internal gas diffusion equations considering the internal reaction rate of porous carbon particles are introduced. Solving these equations, the formulae of the combustion rate of carbon particles are obtained. For large particles the combustion rate may be calculated from the superficial reaction rate concerning the external surface, but the combustion rate of small particles, which can be used in the pulverized coal firing, must be calculated from the above formulae. The facts that the specific combustion rate of the pulverized coal is almost independent of particle size and considerably increased with the increasing of temperature, are explained by the formulae.
