Recently, premixed combustion dominated the field of combustion research worldwide. The current work is a review that addresses the stability, approaches, and emission control of premixed flames in different applications. The study addresses the recent developments made to overcome the combustor operability issues, including flame stability and emission control. The influences of oxidizer and fuel flexibility using oxy-fuel combustion and hydrogen enrichment on combustion efficiency and flame stability are investigated. Furthermore, the influences of operating and combustor design conditions on flame characteristics are discussed. Recent developments in swirl-stabilized combustor are analyzed and summarized. The effect of premixing on emissions is investigated, considering a variety of design and operating conditions in different applications. As per this survey, the application of fully premixed combustion in the industrial area is even so defined; all the same, promising designs are under development. The challenges regarding the application of the premixed combustion technology in the industrial field are discussed. The role of numerical CFD techniques to predict the reacting flow field and heat release in premixed combustion mode is addressed. A numerical case study is presented to address the premixed combustion characteristics in a swirl stabilizer gas turbine combustor.
