Thermal-pulverization high-efficiency combustion device and method for high-volatile-component carbon-containing fuel

The invention discloses a thermal-pulverization high-efficiency combustion device and method for high-volatile-component carbon-containing fuel. A thermal-pulverization fluidized bed furnace is adopted to heat and pulverize the high-volatile-component carbon-containing fuel so as to produce a high-temperature semi-coke power and gas mixture. The high-temperature semi-coke power and gas mixture is fed into the boiler, and complete combustion is performed in a hearth through staged air distribution. Ash obtained after combustion is discharged out through a dust remover at the tail portion. The efficient utilization of the high-volatile-component carbon-containing fuel is achieved, the problem of the high costs for thermal pulverization of an existing high-volatile-component carbon-containing fuel is solved, the bottleneck of big utilization difficulty of the high-volatile-component carbon-containing fuel is broken through and the utilization efficiency is improved by adopting a thermal-pulverization method. 本发明
