The performance of two different burner designs, single central orifice (SCO) and single annular orifice (SAO), was examined under oxycoal conditions in a downfired oxycoal pilot plant. Based on detailed in-flame measurements combined with CFD predictions, the main parameters influencing the stability of an
pulverised coal swirl flame were identified and investigated.
The oxycoal flame was experimentally stabilised at the burner quarl by: increasing concentration above 34 vol% without ...
