Abstract
A method and apparatus for burning fuel in an annular-nozzle burner wherein a compact flame is generated by inhibiting the dispersion of fuel particles and concentrating the fuel particles in a primary combustion area having a high rate of radiant heat transfer between the fuel particles by maintaining a sufficiently high velocity of the fuel particles and causing them to undergo esentially linear flow in a direction substantially parallel to the axis of the burner.
Claims27
a method of burning fuel in a burner having an annular-nozzle for injecting primary air and fuel into secondary air of a combustion chamber, said method comprising the steps of:
- directing said fuel into said secondary air through said annular nozzle so that said fuel is delivered essentially only therethrough;
- generating a compact flame by inhibiting dispersion of fuel particles and concentrating said fuel particles in a primary combustion area of said flame;
- and,
- maintaining a sufficient velocity of said fuel particles relative to said secondary air to thereby obtain a high rate of radiant heat transfer between said fuel particles.
A method of burning fuel in a burner of the type including a source of fuel particles;
- an inner core area;
- and, means for delivering said fuel into a combustion chamber, said method comprising the steps of:
- ejecting said fuel into said combustion chamber only through a fuel feed area substantially surrounding said inner core area;
- and,
- inhibiting radial dispersion of said fuel particles and concentrating said fuel particles in a primary combustion area.
