    Abstract: A burner for the combustion of a fuel plus air mixture comprises a central nozzle pipe having an inner surface with a portion which diverges outwardly. An axially moveable plug is positioned within the nozzle pipe and includes an outer wall with a diverging section extending within the diverging section of the nozzle pipe. By axially moving the plug, the cross sectional area of the space between the diverging surfaces increases and decreases for respectively decreasing and increasing the velocity of the fuel plus air mixture passing through the nozzle space. This reduces the formation of NO.sub.x and the length of the flame produced by the burner.

    Abstract: A compound spin vane (CSV) for use in an air passage of a fossil fuel-fired burner. In one embodiment, the CSV is a multi-piece construction of platelike outer and inner vane elements connected to an intermediate platelike rail element. In another embodiment, the CSV includes at least two and possibly three vane portions, rigidly interconnected in spaced lateral relationship with respect to each other. If desired, the vane portions may be simple, curved planar surfaces, and may be arranged with trailing edges arranged at angles with respect to each other. The invention may be employed as a replacement for flat spin vanes found in secondary air passages of known single and dual register burners. When used in such manner in a single register burner, the invention changes secondary air flow characteristics so as to mimic those commonly found in a dual register burner.

    Abstract: A coal burner with impeller for a furnace has a housing containing a plurality of sets of blades which direct the fuel from the coal nozzle into a plurality of non-intersecting flows directed obliquely towards the longitudinal axis of the housing. The non-intersecting flows create a fuel-rich devolatilization zone and an air-rich char burnout zone within the furnace and limit the flame length of the burner.

    Abstract: A primary air exchange device for a burner of a pulverized fuel, such as coal, with burner including a supply line through which a primary air and pulverized fuel mixture is supplied. A separator having its inlet within the supply line is dimensioned to receive and remove approximately one half of the primary air while the remaining half of the primary air moves past the separator. Additionally approximately 90% of the pulverized fuel passes the separator while only about 10% of the pulverized fuel enters the separator along with approximately one half the primary air. This air and small quantity of fuel mixture is delivered from the separator to a nozzle where it is discharged into a burner throat of a furnace. Hot air is injected into the remaining mixture of half the primary air plus the large percentage of pulverized fuel to heat this fuel before it is injected into the furnace for ignition.
