In order to supply a clear grasp on the burnout of swirling combustors for a 660 MW supercritical unit swirl coal-fired combustion boiler and its burnout offers giant damages to this electricity plant,a numerical investigations via the use of ANSYS FLUENT 14.0 on the tricky mechanism of burnout are carried out via us.This numerical lookup concentrates on the go with the flow discipline for a single swirling combustor,the glide subject of the complete swirling combustors,the temperature discipline for the three principal combustors and the over furnace air nozzles,and the temperature evolution alongside the axis of the swirling combustor from the outlet of the combustor to the route of the essential waft field.From the above researches,some key techniques are proposed via us in order to limit the harm of burnout of combustors.This numerical lookup is extra really helpful for the protection and steady strolling of swirling combustors,and it is based totally on theoretical research,which supply greater convincible motives on the environment friendly and secure going for walks of this combustor.
