Non-centric oxy-fuel burner for glass melting systems

Abstract

A burner and method of combustion for a furnace or a forehearth includes a gas delivery member and a fuel delivery member having a portion thereof disposed at an interior of the gas delivery member and offset or angled from a longitudinal axis of the gas delivery member to provide gaseous oxidant and fuel flows for combustion.

1 . A burner for use in a furnace or a forehearth, comprising a gas delivery member, and a fuel delivery member having a portion disposed at an interior of the gas delivery member and offset from a longitudinal axis of the gas delivery member. 
   
   
       2 . The burner according to  claim 1 , wherein a portion of the gas delivery member and the portion of the fuel delivery member are parallel with each other. 
   
   
       3 . The burner according to  claim 1 , wherein the portion of the fuel delivery member is disposed at an angle at the interior of the gas delivery member. 
   
   
       4 . The burner according to  claim 1 , wherein the gas delivery member and the fuel delivery member are formed as an integral unit. 
   
   
       5 . The burner according to  claim 1 , wherein each of the gas delivery member and the fuel delivery member are adapted for rotational movement. 
   
   
       6 . The burner according to  claim 1 , wherein the gas delivery member comprises a gas pipe. 
   
   
       7 . The burner according to  claim 1 , wherein the gas delivery member comprises a first gas pipe with a first interior; and a second gas pipe with a second interior disposed in the first interior of the first gas pipe, the second interior sized and shaped to receive a portion of the fuel delivery member therein. 
   
   
       8 . The burner according to  claim 1 , wherein the fuel delivery member comprises a fuel pipe. 
   
   
       9 . The burner according to  claim 1 , wherein the fuel delivery member comprises a plurality of fuel pipes. 
   
   
       10 . The burner according to  claim 9 , wherein the plurality of fuel pipes are an integral unit. 
   
   
       11 . The burner according to  claim 9 , wherein the plurality of fuel pipes are disposed at an angle at the interior of the gas delivery member. 
   
   
       12 . The burner according to  claim 1 , further comprising at least one support member disposed to support the gas delivery member in spaced relation with respect to the fuel delivery member. 
   
   
       13 . A method for combusting product in a furnace or a forehearth, comprising providing a flow of gaseous oxidant along a first flow path to the furnace; providing a flow of gaseous fuel along a second flow path offset from the first flow path to the furnace; exposing the first flow path to the second flow path; and combusting the gaseous oxidant and the gaseous fuel to provide a non-circular burn area. 
   
   
       14 . The method according to  claim 13 , wherein the first flow path and the second flow path are angled with respect to each other. 
   
   
       15 . The method according to  claim 13 , further comprising providing another flow of gaseous oxidant along a third flow path to the furnace, the third flow path disposed within the first flow path and arranged to receive the second flow path therein. 
   
   
       16 . The method according to  claim 13 , wherein the first flow path and the second flow path are alterable with respect to each other to control the disposition of the non-circular burn area. 
   
   
       17 . The method according to  claim 13 , wherein the gaseous oxidant is selected from the group consisting of oxygen, oxygen and nitrogen, oxygen and other noble gases, and combinations thereof. 
   
   
       18 . The method according to  claim 13 , wherein the gaseous fuel is selected from the group consisting of natural gas, propane, liquid petroleum gas, synthetic gas, and combinations thereof. 
   
   
       19 . The method according to  claim 18 , wherein the synthetic gas is derived from a source selected from the group consisting of organic solid sources, organic liquid sources, organic gaseous sources, and combinations thereof.
