Thrower wheel of a mechanical stoker

Abstract

A thrower wheel of a mechanical stoker is provided. The thrower wheel includes a plurality of blades, which are disposed on a base plate. A height of the blades increases in a radial direction in at least one area and optionally remains the same in one or more remaining areas, and the height of the blades is less at the inner end of the blades than at the outer end of the blades.

         10 . A thrower wheel of a spreader stoker, comprising:
 a base plate with a hub; and   a plurality of blades disposed on the base plate,   wherein a height of the blades increases in a radial direction at least in one section, and   wherein the height of the blades at the inner end of the blades is less than at the outer end of the blades.   
     
     
         11 . The thrower wheel as claimed in  claim 10 , wherein the height remains unchanged in one or more sections of the blades. 
     
     
         12 . The thrower wheel as claimed in  claim 10 , wherein the height of the blades increases from the inner end on in a first section and subsequently remains the same in a second section as far as the outer end. 
     
     
         13 . The thrower wheel as claimed in  claim 10 , wherein the height of the blades at the inner end is equal to zero. 
     
     
         14 . The thrower wheel as claimed in  claim 10 , wherein the height of the blades at the inner end is less than half the maximum height of the blades. 
     
     
         15 . The thrower wheel as claimed in  claim 10 , wherein the inner ends of the blades have a clearance relative to the hub of the base plate. 
     
     
         16 . A spreader stoker, comprising:
 a housing with a feed opening for fuel;   an ejection opening for fuel; and   a thrower wheel, the thrower wheel comprising:
 a base plate with a hub; and 
 a plurality of blades disposed on the base plate, 
 wherein a height of the blades increases in a radial direction at least in one section, and 
 wherein the height of the blades at the inner end of the blades is less than at the outer end of the blades. 
   
     
     
         17 . The spreader stoker as claimed in  claim 16 , wherein the feed opening for fuel is concentric to an axis of rotation of the thrower wheel such that fuel is applied onto the thrower wheel in a direction of the axis of rotation. 
     
     
         18 . The spreader stoker as claimed in  claim 16 , wherein the ejection opening is a circumferential ejection opening being disposed normal to an axis of rotation of the thrower wheel such that fuel in a plane of the thrower wheel is ejected from the thrower wheel. 
     
     
         19 . The spreader stoker as claimed in  claim 17 , wherein the ejection opening is a circumferential ejection opening being disposed normal to an axis of rotation of the thrower wheel such that fuel in a plane of the thrower wheel is ejected from the thrower wheel. 
     
     
         20 . The spreader stoker as claimed in  claim 16 , wherein a maximum height of the blades is reached only outside of a diameter of the feed opening. 
     
     
         21 . The spreader stoker as claimed in  claim 17 , wherein a maximum height of the blades is reached only outside of a diameter of the feed opening. 
     
     
         22 . The spreader stoker as claimed in  claim 18 , wherein a maximum height of the blades is reached only outside of a diameter of the feed opening. 
     
     
         23 . The spreader stoker as claimed in  claim 16 , wherein the height of the blades remains unchanged in one or more sections of the blades. 
     
     
         24 . The spreader stoker as claimed in  claim 16 , wherein the height of the blades increases from the inner end on in a first section and subsequently remains the same in a second section as far as the outer end. 
     
     
         25 . The spreader stoker as claimed in  claim 16 , wherein the height of the blades at the inner end is equal to zero. 
     
     
         26 . The spreader stoker as claimed in  claim 16 , wherein the height of the blades at the inner end is less than half the maximum height of the blades. 
     
     
         27 . The spreader stoker as claimed in  claim 16 , wherein the inner ends of the blades have a clearance relative to the hub of the base plate.
