WRC/WRO Wide Range Burners

Wide Range Burner Units designed for oil or gas/oil firing and both pressurized and nonpressurized applications. The output capacity is twice that of a 780 series burner and turndown range is greatly increased. These advantages are accomplished by supplying controlled combustion air through the burner and around the burner nose. Air flows are separately valved but jointly controlled. Where there is much excess air, such as in air heater, the fuel capacities can be increased by as much as 2.5 times sealed-in stoichiometric capacity.
