Abstract: A power generation system in which the combustion heat of hydrocarbon gas is used to heat the steam for power generation; at the same time, the exhaust heat thereof is used to dry and thy-distill low rank coal. The power generation system includes: a dry distillation step for dry-distilling low rank coal of high moisture content; a cooling step for cooling the fixed carbon obtained in the dry distillation step; a combustion step in which hydrocarbon gas obtained in the dry distillation step is used as the main fuel; and a power generation step in which there are provided a power generator moving a steam turbine by main steam generated in the combustion step and a condenser.

Abstract: A fixed carbon production device is provided with: a quench chamber for collecting fixed carbon; a dry distillation furnace which is erected and fixed in the quench chamber and into which raw material coal is fed; a dry distillation unit which is polygonal in horizontal cross-section and is partitioned by a separating wall which partitions the inside of the dry distillation furnace in the vertical direction; a dry distillation mini-furnace which is polygonal in horizontal cross-section and which is partitioned by a partition which partitions the inside of the dry distillation unit in the vertical direction; a pipe heating means which is arranged on the separating wall of the dry distillation unit and the partition of the dry distillation mini-furnace and which dry-distills the raw material coal; and a collection path for collecting fixed carbon collected in the quench chamber.

Abstract: 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.
