COMBUSTION FIRE GRATE FOR GARBAGE INCINERATOR

摘要

PROBLEM TO BE SOLVED: To prevent burning troubles of a fire grate block by forming a slant surface on the downstream side top surface of the fire grate block being inclined downward on the downstream side so that a liquefied resin can flow to the downstream side to eliminate the retention of the liquefied resin at a low cost. SOLUTION: A top surface wall 21 of a fire grate block 11 on the downstream side is constituted of a flat part 21a on which slides a slide contact part 22b of the fire grate block 11 on the upstream side and a slant surface 21b to be inclined downward to the front at an angleαdeg. of inclination from the front rim 21c of the flat part 21a. With a drive to advance or retract a mobile fire grate train, the liquefied resin flowing down onto the flat part 21 is extruded forward by a slide contact part 22b of an upstream side fire grate block 11 to be discharged to the slant surface 21b and flows down onto the downstream side fire grate block 11 by the dead load. This eliminates burning of the liquefied resin staying on the fire grate block 11 thereby preventing burning loss of the fire grate block 11 attributed to the resins.
