The Fujian inferior quality anthracite is one of coal sorts which are most difficult to burn in the world at present.Realization of highly effective and clean combustion of said coal sort is always a difficult technical problem.On the basis of reviewing the development of CFB technology

some key technical measures for realizing combustion optimization of Fujian inferior quality anthracite have been put forward as follows:burners under the bed + pulsating coal feed on the bed

using double return-material receivers

enhancing the burning temperature

increasing the height of furnace

lowering the bed pressure

and controlling particle size of the raw coal etc.
