Abstract
The invention includes a grate system for a boiler. The grate system includes a grate unit and a side header guard. The grate unit supports fuel during combustion thereof, and has an upper surface, a lower surface, and upturned lateral edges. The side header guard is arranged along a side wall of the boiler and has upwardly and downwardly projecting fin portions. The upwardly projecting fin portion is adapted and configured to extend over and protect the boiler side wall from abrasion by fuel. The downwardly projecting fin portion is adapted and configured to extend over the upturned lateral edge of the grate unit, inhibiting passage of fuel therebetween.
