Numerical study on a novel burner designed to improve MILD combustion behaviors at the oxygen enriched condition

A comprehensive investigation of acoustic power level in a moderate or intense low oxygen dilution in a jet-in-hot-coflow under various working conditions

“…Tian et al [12] applied MILD condition to a co-axial-jet I-shaped recuperative radiant tube for further performance enhancement. Xie et al [13] designed a novel burner to improve MILD combustion performance. These authors showed that injecting pure oxygen and an inert gas separately into the furnace leads to more uniform temperature distribution and lower NOx emission.…”

Experimental study on flameless combustion and NO emission with hydrogen‐containing fuels

“…From the viewpoint of controlling the high flame temperature, which is the bottleneck of pure oxygen or oxygen‐enriched combustion technology, both external flue gas recirculation technology 31 and a method for suppressing thermal NO x emission using flameless combustion technology are being considered 32‐34 . Several studies have also been conducted on how to achieve flameless combustion under oxygen‐enriched combustion conditions, including the use of diluents to overcome the high oxygen fraction in the oxidant, preheating of reactants and diluents, and strong internal recirculation induction 35,36 . Flameless combustion requires the use of equipment such as expensive flameless combustion burners, heat exchangers for preheating of reactants, and external flue gas recirculation facilities.…”

Oxygen‐enriched flameless combustion of CH 4 / H 2 / CO mixtures

“…16,17 In addition, MILD combustion-including the opposing concepts of combustion at a low oxygen dilution and oxygen-enriched flameless combustion-is insufficient because it is difficult to control NO x emissions despite high thermal efficiency. Xie et al 18 achieved a NO x reduction of approximately 60% under oxygen-enriched conditions through the application of a novel burner.…”
