2014-4-9 · 300 MW large-scale utility boiler under the standard ring condi-tions was used by Karampinis et al.[18] to perform a numerical investigation for lignite coal and biomass particles at several co- r-ing scenarios. The numerical ndings showed that the burnout rates of lignite char coal decreased in the hopper under co- ring conditions.
