The CVL spreader stoker is an overfeed type with continuous ash discharge.  The stoker is with hydraulic stoker drive and pneumatic/mechanical fuel distributors.  Fuel is burned in suspension as well as on the forward-traveling stoker surface.

Stoker sections are constructed with high quality, heavy duty, heat-resisting cast alloy materials for long life. Adequate access to all areas and external grease fittings maintenance is provided. Individual parts, such as grate sections, can be replaced without major overhaul and without necessitating purchase of large, more expensive sub­assemblies.

Fine particles of fuel are rapidly burned in suspension while coarser, heavier particles are spread evenly on the grates, forming a thin, fast-burning fuel bed.  The fuel feed and air supply rates conform to variations in load and are automatically regulated by the combustion control system. To compensate for variations of the ash content in the fuel, the grate speed can be adjusted. The ash is continuously discharged over the front end of the grate into the ash handling system.

The CVL "GRATE" Hydraulic Drive is a powerful and efficient self-contained unit in a single housing requiring no external piping or equipment. It is constructed of heavy-duty castings and high-strength steel parts,. The capacity of the flow control valve and hydraulic system are such that the rotation of the drive shaft can be infinitely adjusted. The fuel distributor, mounted on the front water wall panel, has gravity fed chute.
