[0012] (5) Specific implementation methods, combined with accompanying drawings
[0013] The dry slag removal machine includes a body 9, wheels are installed under the body, a driving roller 5 and a driven roller 1 are installed on the body, and an endless steel belt 3 is installed on the periphery of the driving roller 5 and the driven roller 1, and one end of the endless steel belt is connected The slag remains 6, and the outlet of the slag remains 6 is connected to the slag cooling machine 7, and there is a slag tank 2 above the endless steel belt.
[0014] The top of the endless steel belt is a working stroke section, and the following of the working stroke section is supported by 4 water-filled mattresses mounted on the body. The bottom of the endless steel belt is the return section, and the following section of the return section is supported by 8 supporting rollers mounted on the machine body.

The dry cinder-removing machine includdes machine body, on the machine body the driving rollers and driven rollers are mounted, as endless steel band is mounted around the driving and driven rollers, the upper portion of the endless steel band is working portion, and the undersurface of working portion of supported by water-changed pad bed mounted on the machine body. Said invention is reasonable in structure, in the course of removing cinder said cinder does not contact with water. In the cinder-cooling machine its cooling medium is air and make-up water of boiler or circulating water, the air absorbing cinder heat can be fed into furnace cavity to help combustion, and the water absorbing cinder heat can raise water temp. of boiler so as to raise heat efficiency of boiler, and the dried cinder can be used as cement clinke.
Description
(1) Technical field [0001] The invention relates to ash treatment equipment belonging to the technical field of boiler auxiliary equipment, in particular to a dry slag remover. (2) Background technology [0002] For large-scale boilers, especially pulverized coal-fired boilers in the range of 100MW-700MW, about 15% of the hot ash after burning is discharged through the slag well at the bottom of the furnace. At present, the treatment of this part of the furnace bottom ash needs to be extinguished and cooled with water, that is, wet slag removal. The disadvantage is that a large amount of water is needed, and the heat contained in the hot slag is not recovered, resulting in waste of water resources and energy. At present, there is also a new type of mesh belt dry slag removal equipment, which has the disadvantages of complex structure, high cost, heavy maintenance workload, high operating cost, and poor adaptability to the impact of coke collapse in the furnace. (3) Conten...
