The invention relates to a fuel conveying
system with a
drying device. The fuel conveying
system comprises a feeding device, a stirring
barrel, a material extruding device, the
drying device and a conveying device, wherein the feeding device comprises a
coal powder hopper and a
sludge hopper; a discharging port of the
coal powder hopper and a discharging port of the
sludge hopper both extend intoa feeding port of the stirring
barrel; the material extruding device comprises a material
barrel with the feeding port communicating with the discharging port of the stirring barrel; an
auger is coaxially and rotationally connected in the material barrel; one end of the material barrel is closed, and a material extruding plate is arranged at the other end of the material barrel; a plurality of material extruding holes are formed in the material extruding plate; a preheating mechanism is arranged on the
peripheral wall of the material barrel; the
drying device comprises a drying barrel arrangedat the end, close to the material extruding plate, of the material barrel; a hot air
pipe communicates in the drying barrel; and a material overturning mechanism is arranged in the drying barrel. According to the fuel conveying
system, a
coal powder and
sludge mixture is preheated through the preheating mechanism and then extruded into strips from the material extruding plate, drying is conductedthrough the drying barrel, the coal powder and sludge mixture can be conveyed into a
hearth to be combusted at a good proportion, and the good
combustion heat value of the coal powder and sludge mixture is ensured.
