Abstract
The utility model relates to a coal firing boiler, in particular to a vertical smoke-dust eliminating coal firing boiler. A grate consists of a boiler disk (5), a rotary shaft (6), a transmission gear (7) and a motor. One end of the rotary shaft is fixedly connected with the center point of the grate, and the other end is meshed with the transmission gear which is connected with an output shaft of the motor. A plurality of protruding cinder-crushing bars (10) are arranged on the boiler disk to crush cinders and cokes automatically. A coal hopper is arranged on the upper part of the boiler disk, the coal is fed into an upper port of an inclined groove of the coal hopper, and the coal is automatically transferred to the boiler disk against an inclined face of the inclined groove and the gravity of the coal. The coal in the coal hopper can be equally distributed to the boiler disk as the revolving of the boiler disk. Under effects of the boiler disk rotation and the cinder-crushing bars on the boiler disk, the coal on the grate can be thoroughly burnt, and the smoke and dust can be eliminated so as to enhance the combustion efficiency. The utility model is characterized in that the structure is reasonable; the heating efficiency is high; pollutions to environment can be reduced and both smokes and dusts can be eliminated, etc.
