PURPOSE: A heater for solid fuel is provided to supply the solid fuel to combustion chamber and to improve durability of a driving motor by easily releasing from hanging of the solid fuel. CONSTITUTION: A heater for solid fuel comprises combustion chamber, a smoke discharging device, and a fuel supply device(50). The combustion chamber generates heat of fire and heat while the solid fuel is inserted and combusted. The smoke discharging device discharges the smoke generated in the combustion chamber by guiding to the outside. The fuel supply device is located in one side of the combustion chamber, supplies the solid fuel to the combustion chamber, and includes a hopper(51), a transfer pipe(52), a supply pipe(53), a transfer screw(54), a rotary shaft(55), a driving motor(56), a controller(57), and a signal transmitter. The hopper is built in a case(CS) which is installed in one side of the combustion chamber and includes storage. The transfer pipe is detachably combined in a vent(51a) of the hopper and transfers the solid fuel. The supply pipe supplies the solid fuel which is transferred to the transfer pipe to the combustion chamber. The transfer screw transfers the solid fuel to the combustion chamber. The rotary shaft delivers rotatory power to the transfer screw. The driving motor is detachably fixed in the end of the rotary shaft and rotates the transfer screw. The controller supplies the power to the driving motor, rotates the driving motor, and controls the driving of the transfer screw. The signal transmitter rotates the driving motor and the transfer screw in a reverse direction by providing reverse rotation signal to the controller and releases from hanging of the solid fuel. |
