Grate or industrial furnaces and make it effective stacked solid fuel combustion components. Entire grate consists of two parts of the framework and grate. Grate usually between cast iron pieces assembled with the sheet to maintain the necessary ventilation slits, and often at the bottom grate can adjust the air volume set of separated plenum to allow air to enter through the gap layer combustion ash fuel burn after slag discharged by manual or mechanical methods. Grate fixed, mobile, reciprocating, vibration and lower feed type and other types. Reciprocating Grate a use of a reciprocating grate movement to achieve coal, slag, call the fire burn mechanized equipment. Reciprocating grate grate can be divided according to arrangement inclined reciprocating grate and reciprocating grate A tilted horizontal reciprocating grate inclined ladder-type, there are alternate arrangement of activities grate grate and fixed grate slices. B horizontal reciprocating grate is fixed and movable grate grate staggered composition, grate overlapping each other.
