Abstract
A water-coolable grate plate including a top surface, oppositely disposed sides and at least one cooling channel which is thermally connected to the top surface. The cooling channel connects a first coolant port, which is substantially centered between the sides of the grate plate, to a second coolant port, which is positioned at a distance from the first coolant port.
Claims29
A feed grate including a grate plate carrier and a plurality of grate plates each grate plate comprising:
- oppositely disposed top and bottom surfaces;
- oppositely disposed first and second ends;
- oppositely disposed first and second sides defining a centerline;
- therebetween
- a cooling system including a cooling channel and at least a first coolant port located at centerline and positioned at the bottom surface of the grate plate, the first coolant port being in fluid communication with the cooling channel and adapted for connection to a conduit;
- and
- a top surface extending from the first side to the second side for holding solid materials to be incinerated, the top surface being thermally connected with the cooling channel wherein the grate plates are positioned first end to second end in overlapping fashion, one behind the other.
A feed grate comprising a plurality of grate plates, and grate plate carriers each grate plate having:
- oppositely disposed top and bottom surfaces;
- oppositely disposed first and second sides defining a centerline;
- therebetween
- a cooling system including a cooling channel and at least a first coolant port located at the centerline and positioned at the bottom surface of the grate plate, the first coolant port being in fluid communication with the cooling channel and adapted for connection to a conduit;
- and
- a top surface extending from the first side to the second side for holding solid materials to be incinerated, the top surface being thermally connected with the cooling channel and, each grate plate carrier extending from the first side to the second side of each one of the grate plates.
A feed grate including a plurality of grate plates, each grate plate comprising:
- oppositely disposed top and bottom surfaces;
- oppositely disposed first and second sides;
- a cooling system including a cooling channel extending from a first coolant port to a second coolant port, the first coolant port being positioned at the bottom surface of the grate plate, the second coolant port being positioned at a distance from the first coolant port, the cooling channel having a cross section that varies between the first and second coolant ports;
- and
- a top surface extending from the first side to the second side for holding solid materials to be incinerated, the top surface being thermally connected with the cooling channel.
A feed grate including a plurality of grate plates, each grate plate comprising:
- oppositely disposed top and bottom surfaces;
- oppositely disposed first and second sides;
- a cooling system including a cooling channel extending from a first coolant port to a second coolant port, the first coolant port being positioned at the bottom surface of the grate plate, the second coolant port being positioned at a distance from the first coolant port, one of the first and second coolant ports being a coolant intake and the cooling channel having a cross section which is larger adjacent the coolant intake than it is adjacent the other of the first and second coolant ports;
- and
- a top surface extending from the first side to the second side for holding solid materials to be incinerated, the top surface being thermally connected with the cooling channel.
A feed grate including a plurality of grate plates, each grate plate being composed of cast metal formed in a casting and comprising:
- oppositely disposed top and bottom surfaces;
- oppositely disposed first and second sides:
- a cooling system including a cooling channel and at least a first coolant port positioned at the bottom surface of the grate plate, the first coolant port being in fluid communication with the cooling channel and adapted for connection to a conduit;
- and
- a top surface extending from the first side to the second side for holding solid materials to be incinerated, the top surface being thermally connected with the cooling channel.
