Abstract

A disclosed fuel injector provides mixing of fuel with airflow by surrounding a swirled fuel flow with first and second swirled airflows that ensures mixing prior to or upon entering the combustion chamber. Fuel tubes produce a central fuel flow along with a central airflow through a plurality of openings to generate the high velocity fuel/air mixture along the axis of the fuel injector in addition to the swirled fuel/air mixture.

Burner for reduced nox emission and control of flame spread and length

Patent Goodnight, H E ; Martin, R R ; Reed, R D

A burner is described for reduced nox emission and also for the control of the shape of the flame as regards its length and spread, comprises a first combustion zone, which is contained within a cylindrical chamber lined with refractory material. A burner tube is inserted through an opening in the upstream end of the first combustion zone, the burner including means for providing and burning liquid and gaseous fuel. A first air plenum is provided upstream of the first combustion zone with means for supplying less-than-stoichiometric combustion air in a tangential swirling manner, prior to entering the first combustionmore »« less
Ducted fuel injection: A new approach for lowering soot emissions from direct-injection engines

Journal Article Mueller, Charles J. ; Nilsen, Christopher W. ; Ruth, Daniel J. ; ... - Applied Energy

Designers of direct-injection compression-ignition engines use a variety of strategies to improve the fuel/charge-gas mixture within the combustion chamber for increased efficiency and reduced pollutant emissions. Strategies include the use of high fuel-injection pressures, multiple injections, small injector orifices, flow swirl, long-ignition-delay conditions, and oxygenated fuels. This is the first journal publication paper on a new mixing-enhancement strategy for emissions reduction: ducted fuel injection. The concept involves injecting fuel along the axis of a small cylindrical duct within the combustion chamber, to enhance the mixture in the autoignition zone relative to a conventional free-spray configuration (i.e., a fuel spray thatmore »« less
