Abstract
Embodiments disclosed herein are directed to a combustion system including at least one fuel flow equalizer for reducing fuel flow velocity distribution and improving flame stabilization within a combustion space. Additionally, a charged flame anchoring apparatus may be positioned above the at least one fuel flow equalizer for attaching the flame thereto and improving flame stability.
Claims20
A combustion system, comprising:
- at least one burner nozzle configured to discharge fuel into a combustion space sized and configured to at least partially contain a flame produced during combustion of the fuel and an oxidizer;
- at least one fuel flow equalizer positioned downstream from the at least one burner nozzle, the fuel flow equalizer including a plurality of openings sized and configured to allow the fuel to pass therethrough;
- a flame anchoring apparatus positioned downstream from the at least one fuel flow equalizer;
- and
- a voltage power supply electrically coupled to the flame anchoring apparatus, the voltage power supply being configured to bias the flame anchoring apparatus so that the flame is attracted to the flame anchoring apparatus.
2 more elements
A method for stabilizing a flame within a combustion space, the method comprising:
- discharging fuel from at least one nozzle into a combustion space;
- passing the fuel through at least one fuel flow equalizer structure positioned downstream from the nozzle;
- igniting the fuel and an oxidizer to produce a flame;
- applying an electrical potential to a flame anchoring apparatus effective to anchor the flame to the flame anchoring apparatus.
1 more element
A flame control system, comprising:
- at least one burner nozzle configured to discharge fuel into a combustion space sized and configured to at least partially contain a flame produced during combustion of the fuel and an oxidizer;
- at least one fuel flow equalizer disposed downstream from the burner nozzle, the fuel flow equalizer including a plurality of openings sized and configured to allow the fuel to pass therethrough;
- a flame anchoring apparatus positioned downstream from the at least one fuel flow equalizer so that the fuel exiting the at least one fuel flow equalizer encounters the flame anchoring apparatus;
- a charger configured to charge at least one of the flame or the fuel to form a charged flame;
- and
- a voltage power supply electrically coupled to the flame anchoring apparatus and configured to apply an electrical potential thereto that attracts the charged flame to the flame anchoring apparatus.
