PURPOSE: A boiler is provided to improve the combustion efficiency of fuel by supplying air to the fuel when the fuel falls down to a combustion unit. CONSTITUTION: A boiler comprises a combustion unit(30), an exposed passage(32), and a blower(50). Fuel composed of sawdust is supplied to the inside the combustion unit through an injection port. The combustion unit burns the supplied fuel. The exposed passage is connected to one side of the combustion unit and exposes flames generated when the fuel is burned to the outside. The blower is connected to the injection port and supplies air to the fuel to scatter the fuel into the combustion unit. |
