Cast Iron Gas Burner
PERFORMANCE FROM FUEL RICH TO XCES AIR WITH LOW NOX EMISSIONS
These sealed-in, nozzle-mix burners are stable over a wide range of air/gas ratios from large amounts of Xces air, to stoichiometric (chemically correct air/gas ratio); up to 50% Xces fuel (provided additional air for combustion is supplied to the furnace near the burners). Burner can be ignited at rich, lean or correct air/gas ratio, then immediately turned to high fire. NO emissions are low for all air/gas ratios. The most common ratio control system for 1422 Burners uses a cross-connected regulator. When appropriate for the application, fully metered flow systems and fuel only control are very satisfactory. Required gas pressures are low: 2 wg at burner for coke oven gas, less for natural gas. ADVANTAGES OF XCES AIRXces air can improve temperature uniformity by avoiding hot spots in front of burners, by churning furnace atmosphere to reduce stratification, and by creating positive furnace pressure to eliminate cold air infiltration. Xces air can give very high effective burner turndown. Thus a furnace used for high temperature work (such as heat treating at 1000°C with burner firing on stoichiometric air/gas ratio can also be used for low temperatures jobs (such as drawing or drying at 300°C) with burners firing on lean (Xces air) air/gas ratio. There is a potential increase in fuel consumption because of heating extra air. The benefits, such as better products from improved heating, far outweigh the small increase in fuel costs.APPLICATION TEMPERATURESThe 1422 burners can be used with chamber temperatures up to 1100°C. If furnace temperature could rise above 850°C after shutdown, some air should be maintained through the burner to prevent overheating.STANDARD CONSTRUCTION Burner bodies are heat resistant cast iron with Inconel air tubes. Mounting plate and title assembly can be separated from the burner body for installation convenience. Air and gas connection can be rotated in 90° intervals. When reassembling the burner, the pilot and flame detector notches in the tile and mounting must be in proper alignment with the pilot and flame detector connections on the burner body. Burner is complete with cast iron mounting plate and 9” long 1500°C Castable burner tile which must be supported and sealed in a hard refractory furnace wall. When the furnace wall is thicker than the tile length, the tunnel beyond the end of the burner tile should be flared at a 30° or greater included angle, starting at the OD of the tile.
