ABSTRACT:
The present invention relates to a water-cooled grate, which can be cooled while avoiding high and low temperature corrosions. The water-cooled grate comprises: at least one cooling pipe for guiding flow of cooling water; a grate body for placing waste matters to be burned, said grate body being formed with a pipe-receiving portion for receiving the cooling pipe; and a heat transfer controlling member fixed to the pipe-receiving portion for increasing and decreasing heat transfer between the grate body and the cooling pipe by varying thermal resistance to the cooling pipe through thermal deformation according to temperature change of the grate body.
