Definitions
- each disclose coal fired burners that include a flame stabilizer for imparting a swirl to the fuel-air mixture.
- the disclosed flame stabilizers include a plurality of radially spaced- apart vane elements mounted on a ring member which is positioned over a central fuel supply tube. The vanes are shaped and oriented to provide swirled air to the downstream end of the fuel supply tube.
- U.S. Patent No. 5,477,685 to Samuelson which is herein incorporated by reference in its entirety, discloses a swirl stabilized, lean burn injector for a gas turbine combustor.
- a fuel-air mixture exits a centrally positioned nozzle through a plurality of radially-oriented exit ports.
- the length of the recirculation zone is less sensitive to the swirl number and assumes a length of about 2 to about 2.5 times the quarl exit diameter.
- a quarl allows for a high S n to be used without producing a large diameter recirculation zone.
- the swirl strength when the swirl strength is strong, the flame has a tendency to move upstream, deep inside the burner causing damage to the burner components.
- making the mixture richer increases the flame speed. This increase in flame speed causes the flame to travel further upstream into the burner. In addition to damaging the burner hardware, the uncontrolled movement of flame deep into the burner can result in high NOx emissions.
- the swirl number is defined as the ratio of the amount of rotating combustion air going through the burner versus the amount of the combustion air exiting the burner is in an axial flow condition.
- Burner 100 is adapted for making the cyclic combustion process more stable and significantly reduces the tendency for a gas turbine engine using a lean premixed combustion to flame out or to produce pressure pulsations resulting from unstable combustion.
- the center body flame holder 20 and the quarl 80 have two key effects: 1) the point where combustion is initiated is fixed in space, and 2) higher swirl velocities can be obtained without combustion to flash back into the mixing chamber 50 of the burner 100.
- burner 100 The upstream and downstream ends of burner 100 are identified by reference character "U" and "D", respectively.
- the flow of combustion products is separated into distinct zones, namely a main recirculation zone 90 and an outer recirculation zone 92.
- the process of swirling the fuel-air mixture so as to cause the combustion products to travel upstream is commonly used to stabilize combustion.
- the bluff body flame holder 20 anchors the main re-circulation zone 90 into a fixed position.
- the flame front or combustion initiation point 94 of the premixed flow occurs along the outer surface of the main re-circulation zone 90 where the heat and free radicals mix and initiate combustion of the unreacted premixed fuel and air.
