Grate panel, as well as corresponding incineration grate and waste incineration plant

Abstract

The invention pertains to a grate panel for an incineration grate, an incineration grate composed of grate panels, as well as a solid waste incineration plant with such an incineration grate.

1 . A grate panel for an incineration grate with the following characteristics: 
 a) the grate panel has an upper side ( 10 ), a lower side ( 12 ), two long sides ( 14 ,  16 ) and two broadsides;    b) the grate panel comprises at least one device for connecting a support element ( 20 ) adjacent to a first long side ( 14 ), and    c) at least one flow channel ( 32 ) is arranged underneath the upper side ( 10 ) and adjacent to a second long side ( 16 ), wherein air is conveyed along said flow channel ( 32 ) from a region that is situated underneath the grate panel to an opening ( 32   o ) in a section ( 16   u ) of the second long side ( 16 ) that is situated adjacent to the lower side ( 12 ).    
     
     
         2 . The grate panel according to  claim 1 , wherein the grate panel is realized with a plurality of recesses ( 22 ) underneath the upper side ( 10 ), and wherein said recesses are open toward the lower side ( 12 ) and extend from a region ( 14   a ) that is situated adjacent to the first long side ( 14 ) to a region that is situated adjacent to the second long side ( 16 ).  
     
     
         3 . The grate panel according to  claim 1 , wherein the flow channel ( 32 ) of the grate panel extends perpendicular to the long sides ( 14 ,  16 ) of the grate panel.  
     
     
         4 . The grate panel according to  claim 1 , wherein the flow channel ( 32 ) of the grate panel has a length that corresponds to 10-50% of the length of the broadsides.  
     
     
         5 . The grate panel according to  claim 1 , wherein the second long side ( 16 ) of the grate panel extends at an angle α<90° relative to the upper side ( 10 ).  
     
     
         6 . The grate panel according to  claim 1 , wherein the second long side ( 16 ) of the grate panel is angled ( 16   w ) at least once.  
     
     
         7 . The grate panel according to  claim 1 , wherein an upper (outer) wall of the flow channel ( 32 ) is formed by the upper side ( 10 ) and the second long side ( 16 ).  
     
     
         8 . The grate panel according to  claim 1 , wherein a lower (inner) wall ( 30 ) of the flow channel ( 32 ) is formed by a rib extending between walls ( 24 ) that form lateral limitations of the corresponding recess ( 22 ).  
     
     
         9 . The grate panel according to  claim 1 , which lower side ( 12 ) is designed such that the upper side ( 10 ) of the grate panel extends in an ascending fashion from the first long side ( 14 ) to the second long side ( 16 ) when the grate panel is supported on a horizontal surface.  
     
     
         10 . The grate panel according to  claim 1 , which lower side ( 12 ), adjacent to the second long side ( 16 ), is realized with a downwardly protruding projection ( 30   v ).  
     
     
         11 . The grate panel according to  claim 1 , which upper side ( 10 ) is realized thinner in its section ( 10   v ) that is situated adjacent to the flow channel ( 32 ) than in the section ( 10   r ) that lies behind the flow channel ( 32 ).  
     
     
         12 . The grate panel according to  claim 1 , wherein the second long side ( 16 ) is realized thinner in its section that is situated adjacent to the flow channel ( 32 ) than the upper side ( 10 ) in the section ( 10   r ) that lies behind the flow channel ( 32 ).  
     
     
         13 . The grate panel according to  claim 1 , comprising several interconnected segments (T 1 , T 2 ) that adjoin one another in the direction of the long sides ( 14 ,  16 ).  
     
     
         14 . The grate panel according to  claim 13 , wherein the at least one recess ( 22 ) is formed by two adjoining segments (T 1 , T 2 ).  
     
     
         15 . An incineration grate, particularly a reciprocating incineration grate, with a plurality of grate panels according to  claim 1 .  
     
     
         16 . A waste incineration plant with an incineration grate according to  claim 15.
