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 the fixation of coal inside the chute and damage to the combustion chamber caused by freely falling 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 the chute corresponding to a spot on which the fuel is fallen inside the chute. Air injected via the nozzle unit reduces impact caused by the coal falling inside chute. |
