Abstract
Through a renewed design and layout of its burners a 75 t/h bituminous coal fired boiler has undergone a technical modification for adaptation to operating on anthracite coal. Coupled with other relevant structural changes the modified boiler has achieved a stable combustion regime at 60% of rated load without resorting to fuel oil for combustion support when operating on anthracite.
