Ceramic gas fired hearth burner

Abstract

A ceramic hearth burner comprising a cast ceramic main body arranged to be situated within a fire place. The main body has a first chamber and a second chamber. A combustion air regulator is arranged to regulate the amount of air into the first chamber and an outlet is arranged for controlling the flow of fuel into the second chamber. An ignition plate encloses the second chamber which has a plurality of holes for releasing the fuel therein into an ignition area. At least one portal is arranged to channel the combustion air from the first chamber into the ignition area. The regulator is actuated by differential pressure in the ignition area and in the outside air, the pressure in the ignition area being varied by the amount of fuel being ignited.

1 . A ceramic hearth burner comprises: 
 a cast ceramic main body arranged to be situated within a fire place;    a first chamber within the main body;    a second chamber within the main body;    a combustion air regulator arranged to regulate the amount of air into the first chamber;    an outlet arranged to control the flow of fuel into the second chamber;    an ignition plate arranged to enclose the second chamber;    a plurality of holes in the ignition place arranged to release the fuel within the second chamber into an ignition area;    at least one portal arranged to channel the combustion air from the first chamber into the ignition area;    the regulator being actuated by differential pressure in the ignition area and in the outside air, the pressure in the ignition area being varied by the amount of fuel being ignited.    
     
     
         2 . The burner according to  claim 1  wherein the regulator is a one way swing valve located at an open end of the main body at an air intake of the fireplace.  
     
     
         3 . The burner according to  claim 1  wherein the holes are arranged in a pattern to simulate natural flames.  
     
     
         4 . The burner according to  claim 1  wherein the first chamber is located directly below the second chamber and the portals extends upwards through the second chamber and into the ignition area.  
     
     
         5 . The burner according to  claim 1  wherein the ignition plate is removable from the main body.  
     
     
         6 . The burner according to  claim 1  wherein the main body is a solid cast industrial ceramic material.  
     
     
         7 . The burner according to  claim 5  wherein the ignition plate holes are arranged to provide a natural burning pattern during combustion therethrough.
