Abstract
Past fuel injection nozzles have attempted to provide a structure to reduce exhaust emissions, generally NOx using water injection. Such nozzles have failed to attain adequate reduction of exhaust emissions. The present fuel injector structure has resulted in reduced NOx emissions. The structure includes a combustor having an axis a first air flow passage, a second air flow passage, a first annular fuel passage and a second annular fuel passage. Positioned in the first air flow passage is a directing device through which water is introduced in a swirling manner and mixed with the air in the first air flow passage. Fuel is introduced into the first and/or second annular fuel passages and mixed with air in the second air flow passage. The mixtures of air and water, and fuel and air are mixed prior to entering the combustion section. The unique structure swirls the air and fuel and the air and water prior to their meeting and mixing.
