Improvement of fuel oil spray combustion inside a 7 MW industrial furnace : A numerical study
Applied Thermal Engineering(2017)
摘要
•Small spray angles cause delayed fuel ignition, which increases species emissions.•Moderate swirl numbers reduce species emissions and increase the heating output.•Large swirl numbers or spray angles speed up fuel ignition but shorten the flames.•Excessive flame shortening reduces species emissions but also the heating output.
