Abstract [en]

High-temperature air combustion using the high-cycle generator is attracting great interest in mettalurgical industries. Flame configurations play a very important role when a modern regenerative burner system is adopted in an industrial furnace because multi-burners are required. Numerical studies of combustion in a semi-industrial scale test furnace equipped with two sets of two-flame high-cycle regenerative system have been performed and results were compared with experimental values. Influences of flame configurations on combustion properties and NO emissions of LPG with high-temperature air were numerical studies as well as excess air ratio. The flame volume and size were figured out by a parameter named as oxidation mixture ratio. It is found that the flame configurations have strong influences on the combustion and flame properties as well as NO emission. Increasing the excess air ratio leads to increasing of NO emission. Lesser the ratio of fuel/air injection momentum larger is the NO production.
