Stoker incinerators (Hyper Grate)

Hyper Grate with water cooling

JFE Engineering’s Hyper Grate consists of movable grates and fixed grates arranged alternately and horizontally. Each grate faces upward to the direction of the refuse flow, and the movable grate slide back and forth on the fixed grate so that the feeding and mixing of refuse and the supply of air for combustion is most effective. Since the air outlet at the end’s lower face is the only clearance of the fire grates, the volume of falling dust and falling molten aluminum is small. Heat-resistant, abrasion-resistant high chrome cast steel is used for the grates. The back face of grate is provided with a large fin for a self-cooling using combustion air. For high heating value refuse, a water cooling system can be supplied. This system is designed to circulate cooling water through a water pipe laid on the back faces of the grate. The life of such grates is expected to be five or more years.
