Summary: | The invention relates to the technical field of boilers, in particular to a fly ash supplement type coal and biomass coupling combustion device, which is characterized in that a coal and biomass coupling wind powder channel is sleeved outside a central air pipe, and the output ends of the central air pipe and the coal and biomass coupling wind powder channel are coaxially arranged in the same direction; the coal and biomass coupling wind powder channel is sleeved with the supplementary primary air coal ash airflow channel, the output end of the supplementary primary air coal ash airflow channel and the output end of the coal and biomass coupling wind powder channel are coaxially arranged in the same direction, and according to the device, coal ash directly participates in the biomass combustion process and accurately acts on the alkali metal migration process; and the slagging property of the heating surface of the coal coupling biomass power generation boiler is further weakened. The invention further provid |
