A grate of an incinerator using combustible waste as a fuel is provided to allow thermal expansion of grates by splitting the grates into many pieces and assembling the pieces with spacing, to minimize thermal expansion by coating with refractory lining material on the top of the grates, and to prevent clogging of nozzles by blowing off and scraping ashes accumulated on the top of the grates. A grate used in an incinerator has a plurality of wedge shape grate bodies(100) having a fan-shaped cross section, ejection nozzles(120) on the top of the grate bodies facing the same direction to eject air supplied to the grate bodies, an air inlet(101) at the center of an end of each grate body, flanges at the top and the bottom of the air inlet, and a hole at the lower corner of each grate body to connect a grate body with next one.
