Rapper mechanical arrangement of a radiant syngas cooler

Abstract

An embodiment in accordance with the present invention provides a device and method for removing ash from an interior surface of a radiant synthesis gas cooler. The device for removing ash includes a rapper actuator, a striker pin coupled to the rapper actuator including a proximal end and a distal end, and a striker target assembly disposed such that a proximal surface of the striker target assembly is in contact with the distal end of the striker pin and a distal surface is in contact with the surface of the radiant synthesis gas cooler.

1 . A device for removing ash from a surface of a radiant synthesis gas cooler comprising:
 a rapper actuator;   a striker pin coupled to the rapper actuator including a proximal end and a distal end; and   a striker target assembly disposed such that a proximal surface of the striker target assembly is in contact with the distal end of the striker pin and a distal surface is in contact with the surface of the radiant synthesis gas cooler.   
     
     
         2 . The device of  claim 1 , wherein the striker target assembly comprises a striker target plate. 
     
     
         3 . The device of  claim 2 , wherein the striker target plate comprises a cylindrical bar. 
     
     
         4 . The device of  claim 2 , wherein the striker target plate comprises two striker target plates. 
     
     
         5 . The device of  claim 2 , wherein the striker target assembly comprises a wear plate mounted on the interior surface of the radiant synthesis gas cooler such that the wear plate is in contact with the distal end of the striker target plate. 
     
     
         6 . The device of  claim 1 , wherein the device comprises a pneumatic rapper actuator. 
     
     
         7 . The device of  claim 1 , wherein the device comprises an electromagnetic actuator. 
     
     
         8 . The device of  claim 1 , wherein the striker target assembly is movably disposed within the radiant synthesis gas cooler. 
     
     
         9 . A striker target assembly for removing ash from an interior surface of a radiant synthesis gas cooler comprising:
 a tube cage assembly defining a slot;   a striker target plate including a distal surface and a proximal surface, wherein the striker target plate extends through the slot; and   a wear plate mounted on the interior surface of the radiant synthesis gas cooler such that the wear plate is in contact with the distal surface of the striker target plate.   
     
     
         10 . The striker target assembly of  claim 9 , wherein the striker target assembly is movably disposed within the radiant synthesis gas cooler. 
     
     
         11 . The striker target assembly of  claim 9 , further comprising a striker pin in contact with the proximal surface of the striker target assembly. 
     
     
         12 . The striker target assembly of  claim 11 , wherein the striker target plate, the striker pin, and the wear plate are all in alignment. 
     
     
         13 . The striker target assembly of  claim 9 , wherein the striker target plate comprises two striker target plates. 
     
     
         14 . The striker target assembly of  claim 9 , wherein the tube cage assembly comprises a membrane surrounding an outside surface of the tube cage assembly and the membrane defines an opening through which the striker target plate extends. 
     
     
         15 . The striker target assembly of  claim 14 , further comprising a gap between the striker target plate and the membrane. 
     
     
         16 . A method of removing ash from a radiant synthesis gas cooler comprising:
 mounting a wear plate on an interior surface of the radiant synthesis gas cooler from which the ash is to be removed;   contacting a surface of the wear plate with a distal surface of a striker target plate that extends through a tube cage assembly of the radiant synthesis gas cooler;   contacting a proximal surface of the striker target plate with a striker pin; and   inducing a vibration in the interior surface, from which the ash is to be removed, by transmitting a rapping energy through the striker pin to the striker target plate and the wear plate.   
     
     
         17 . The method of  claim 16 , further comprising aligning the wear plate, the striker target plate, and the striker pin. 
     
     
         18 . The method of  claim 16 , further comprising producing a rapping energy using a rapper actuator. 
     
     
         19 . The method of  claim 16 , further comprising mounting the striker target plate movably within the radiant synthesis gas cooler. 
     
     
         20 . The method of  claim 16 , further comprising a striker target plate comprising two striker target plates.
