These hardy nozzle-mix burners have been used for many years on high temperature furnaces such as those for forging steel, melting aluminum or brass, and reheating steel bars or ingots, and on low temperature ovens and air heaters.
4140 Burners are better with 200% or more excess air. They may also be operated with excess fuel without forming carbon if additional combustion air is available in the furnace near the burner. Excess fuel limit with heavy oil is 50% as atomization deteriorates at richer ratios.
Burner Blocks / InstallationBurner blocks are cast refractory rated for 1500° C furnace temperature. They are replaceable in the field, except for the 4140-10A whose mounting must be returned to the factory for burner block replacement.
Jacketed Burner Blocks4140 Burners are available with support jackets around the burner block for applications where the burner block is not supported by furnace refractory. Jackets are available in different metals and have maximum temperature ratings for each application. |
