摘要（英）：

The invention provides a method for cleanly storing and feeding coal slurry fuel of an electric power plant. The method comprises the following processes of: pre-treating coal slurry, protecting and storing the coal slurry, feeding the coal slurry, pumping the coal slurry and feeding the coal slurry with a boiler. The invention also provides a device for cleanly storing and feeding the coal slurry fuel of the electric power plant. The device comprises a coal slurry pre-treating system, a coal slurry protection and storage device, a pre-pressurized feed screw (4), a flashboard valve (3), a coal slurry transmission pump (5), a coal slurry transmission pipeline (6), a rotation type dense material dividing valve (13), a coal slurry feeding device and an electric power plant boiler. The invention overcomes a plurality of defects existing in the prior art and provides the brand new method and the corresponding device for transmitting the cola slurry to the electric power plant boiler.
