ABSTRACT:
A rotary continuous ash discharge stoker having a circular grate which is designed to support burning fuel as it distributes the fuel from the feedpoint over the entire grate, and at the same time provides for the controlled admission of air for combustion of the fuel and also automatically removes from the furnace the remaining ash. The upper grate surface consists of two zones, a central stationary section and an outer rotating section or ring. The central section is inclined and is the main air admitting zone. The outer rotating ring serves to distribute the fuel in the furnace with the aid of a stationary spreader arm, admits the air necessary to complete combustion of the fuel and removes the burned out ash from the furnace with the aid of a stationary ash plow. This rotating ring is supported and guided on rails and rollers which allow for the complete rotation of this section of the grate, and has an improved wear-resistant furnace wall seal at the interface between the outer periphery of the ring and the inner periphery of the furnace wall.
