Most of the abundant naturally occurring low rank coal, which has a high moisture content and a high oxygen content, is transported with poor efficiency; utilized for heating with degraded thermal efficiency because of the loss of heat due to sensible heat for heating moisture and latent heat for vaporizing moisture; and utilized in existing coal combustion facilities with difficulty due to a high volatile component content. A complex system of the present invention for utilizing coal for manufacture of char and raw material gas and electric power generation is adopted to include: a drying unit for drying low rank coal of a high moisture content; a reformer for reforming the low rank coal that has been dried in the drying unit; a fluidized bed combustor for employing, as a fuel, the reformed coal obtained in the reformer; a producer gas supply pipe for supplying a combustion exhaust gas from the fluidized bed combustor as a pyrolytic and gasifying agent to the reformer; and a catalyst reforming unit for reforming a volatile component and the producer gas obtained from the low rank coal reformed in the reformer.
