MICRO-MODULAR AIR DRIVEN COMBUSTION NOZZLE: EXPERIMENTAL AND NUMERICAL MODELLING STUDIES TOWARDS OPTIMAL GEOMETRIC DESIGN

ABSTRACT
Experimental and numerical modelling studies on optimized design of micro-modular air driven combustion nozzle have been developed. Moreover, optimal angle of outlet swirler (vortex generator) connected in series with the nozzle has been analyzed in the context of minimization of NOx in the flue gases. Numerical modelling by ANSYS verifying the experimental data has been carried out. It has been established that an angle of about 20° of the outlet vortex generator has been able to assure optimal flame length and combustion efficiency.
