Abstract
A pulverized-fuel supply unit includes a hopper, first nozzles, second nozzles, a pressurizing-gas supply device, a fluidization-gas supply device, and a pulverized-fuel supply line. The hopper has a hollow to store therein pulverized fuel. The first nozzles are provided to the hopper. The second nozzles are provided to a vertically lower part of the hopper below the plurality of first nozzles. The pressurizing-gas supply device is configured to supply pressurizing gas to increase internal pressure of the hopper. The fluidization-gas supply device is configured to supply fluidization gas to fluidize the pulverized fuel in the hopper. The pulverized-fuel supply line is provided to a vertically lower part of the hopper. The pressurizing-gas supply device supplies pressurizing gas to the first nozzles and the second nozzles. The fluidization-gas supply device supplies fluidization gas to the second nozzles.
