Experimental comparison between steam and water tilt-angle injection effects on NOx reduction from the gaseous flame.

Nitrogen oxide emissions control is a technology that meets the air pollutant reduction criteria in the energy production field, and it becomes more stringent yearly. Thus, this study experimentally compares the effects of direct-water and -steam injections at different tilting angles on NOx emission reduction. Using the experimental study conducted in the Combustion Laboratory of the Mechanical Power Department at the Faculty of Engineering, Minia University, Egypt, the exhaust gas temperature was found to be the main parameter affecting NOx emission.
