FLUENT: How to calculate coal particle burnout time?

alainislas · June 27, 2020, 03:57

Hello,

I am simulating a pulverized coal combustor in Fluent 18.1. The discrete phase is combusting particles, with inert heating, vaporization, devolatilization, combustion and inert heating laws on. Anyone has an idea on how to calculate my particle burnout time?

Thanks

Find the residence time of coal particles in the furnace that will decide the burnout time of coal particles: Refer the blog for CFD modeling of coal fired boiler:
