DOI: 10.1016/j.fuel.2020.119859
Abstract: Abstract Slagging occurs frequently in boilers owing to the usage of low-NOx combustion technologies. Slagging reduces the heat transfer from the water wall and severely affects the operational safety of boilers, especially when low-rank coals,… read more here.
