| 摘要 |
The invention resides in an electrical power generation system comprising means for burning solid carbonaceous fuel, such as brown coal, to generate heat energy which is used to convert water to steam, turbine means driven by the said steam for producing electrical energy, and solid carbonaceous fuel drying means, wherein moist fuel is indirectly heated by steam in the drying means in the absence of introduced air or other gases, whereby water vapor substantially free from air or other gases is driven off from the fuel for further use and the dried fuel is passed to the burning means. Preferably, the solid carbonaceous fuel drying means is in the form of a fluidized bed in which the fluidizing medium is water vapor. Further, the fluidized bed may be indirectly heated by saturated steam which transfers heat to the solid carbonaceous fuel and becomes condensed.
