The present invention relates to a fire grate of an incinerator. Inside the incinerator, a plurality of roasters are placed in a shape of stairs making a plurality of layers as a supporting means for waste to be incinerated such as industrial and environmental waste placed in the incinerator. The roasters are in the shape of ┬ and ┻, and the combining part, where a pair of the ┬ and the ┻ are combined, is formed in a distorted shape of┏┛. The present invention has the plurality of roasters in a mobile shape on a moving frame and drives a plurality of rotors simultaneously to burn by consecutively pushing the floor material by a minimum driving, and to increase a combustion efficiency and reduce costs for operation and installation following the incineration of waste. As the operation and composition are simplified, the malfunctions and repair are minimized. As the roasters have shapes of ┬ and ┻ and the combining part, where a pair of the ┬ and the ┻ are combined, is formed in a distorted shape of ┏┛; the space of the combining part between roasters is reduced to a minimum by thermal expansion, and the floor material is prevented from falling during combustion. In addition, as an air passage is always opened for the air for combustion to pass through, a synergy effect of combustion efficiency is maximized by the air passage along with an air injection hole for combustion formed on the top surface. Moreover, fire on a bottom is reduced to prevent a lowered performance of a grate driving unit and a reduced life. |
