A present invention relates to a boiler supplying device including a circulating flow layer with a nozzle unit which supplies coal to the inside a combustion chamber and, especially, which prevents damage to the combustion chamber caused by coal supplied to the combustion chamber via a chute. For accomplish the purpose, the boiler supplying device including the circulating flow layer with the nozzle unit of the present invention includes the chute which is connected to the combustion chamber to be inclined in order to supply fuel to the combustion chamber; a feeder which is mounted on the longitudinal upper part of the chute and which inserts the stored fuel; and the nozzle unit which is mounted on a lateral wall of the combustion chamber connected to the chute and which injects air inside the combustion chamber. The air injected via the nozzle unit flows along the chute and scatters the coal, which inserted inside the combustion chamber, inside the combustion chamber. |
