Infrared ray gas burner

Abstract

An infrared ray gas burner comprises an ignition valve, a nozzle, an ejector, a furnace chamber, a porous combustion radiant panel and an ignition needle. An ignition nozzle is placed in the furnace chamber, a sundries baffle is provided in the furnace chamber below the porous combustion radiant panel and above the ignition nozzle and the ignition needle is set above the porous combustion radiant panel, so the gas for ignition ejected from the ignition nozzle quickly mixes with the air inside the furnace chamber, and the gas-air mixture escapes from fire holes of the porous combustion radiant panel above the ignition nozzle. The gas concentration of the mixed gas is relatively high and suitable for igniting, the main burner can be quickly ignited, there is no black smoke, obviously incomplete combustion, and it brings a high ignition rate.

1 . An infrared ray gas burner comprising:
 an ignition valve, a nozzle, an ejector, a furnace chamber, a porous combustion radiant panel, and an ignition needle;   wherein an ignition nozzle passes through the furnace chamber and is settled in a body of the furnace chamber and below the porous combustion radiant panel, a sundries baffle is provided in the furnace chamber below the porous combustion radiant panel and above the ignition nozzle, the ignition needle is set above the porous combustion radiant panel that is set above the ignition nozzle, a needle apex of the ignition needle is placed 1 mm to 10 mm above the porous combustion radiant panel.   
     
     
         2 . The burner of  claim 1 , wherein the ignition needle and a housing of the furnace chamber form an ignition circuit. 
     
     
         3 . The burner of  claim 1 , wherein the burner is a double ring burner comprising an inner ring and an outer ring. 
     
     
         4 . The burner of  claim 1 , wherein in that the porous combustion radiant panel is selected from the group consisting of a porous ceramic radiant panel, a metal mesh combustion radiant panel, a metal fiber combustion radiant panel, a metal honeycomb bodies combustion radiant panel, a foam metal combustion radiant panel, and a wire mesh combustion radiant panel or a metal hole combustion radiant panel. 
     
     
         5 . The burner of  claim 1 , further comprising an accidental flameout protection device, and wherein the ignition needle comprises flame ionization probe of the accidental flameout protection device. 
     
     
         6 . The burner of  claim 1 , wherein the porous combustion radiant panel has a shape selected from the group consisting of a circle, a rectangle, a square, a trapezoid or a combination thereof. 
     
     
         7 . The burner of  claim 2 , wherein the housing of the furnace chamber is an ignition negative pole. 
     
     
         8 . The burner of  claim 2  wherein the ignition circuit further comprises, an independent ignition negative pole. 
     
     
         9 . The burner of  claim 3 , wherein the ignition needle and the sundries baffle are placed in one of the inner ring or the outer ring of the double ring burner. 
     
     
         10 . An infrared ray as burner comprising:
 an ignition valve;   a nozzle extending from the ignition valve;   an ejector extending from the nozzle;   a furnance chamber connected with the ejector and comprising a porous combustion radiant panel disposed onto an upper surface of the furnance chamber, wherein an ignition needle is disposed adjacent the porous combustion radiant panel;   an ignition nozzle connected with the ignition valve and disposed within the furnance chamber below the porous combustion radiant panel; and   a sundries baffle disposed within the furnace below the porous combustion radiant panel.   
     
     
         11 . The burner of  claim 10 , wherein the sundries baffle is positioned and above the ignition nozzle. 
     
     
         12 . The burner of  claim 10 , wherein the ignition needle is positioned above the ignition nozzle. 
     
     
         13 . The burner of  claim 10 , wherein the ignition needle comprises an apex, and wherein the apex is position 1 mm to 10 mm above the porous combustion radiant panel.
