The ventilation area ratio of the reverse push-through furnace type is generally not more than 1%.

[0087] For the garbage incinerator, the grate piece needs to withstand mechanical force at a certain temperature, needs to have certain strength, needs to have the characteristics of corrosion resistance and wear resistance, and needs to have certain hardness, so the various components of the grate piece need to be considered. The dynamic grate reinforcing rib plate 29 and the static grate reinforcing rib plate 49 strengthen the grate piece and increase the strength of the grate piece.

[0088] The utility model discloses a grate piece, the head has the protrusion of certain height, and the garbage can be well turned over and stirred when the movable grate protrusion 22 and the static grate protrusion 42 reciprocate, and the garbage can be better burned.
