PURPOSE: A heating furnace with a heating source blocking device is provided to block the inflow of dust with a screen part and to prevent the inflow of air during discharge of materials, thereby reducing energy loss. CONSTITUTION: A heating furnace comprises a body part(10) including an opening(11) for discharging materials(S), a door part(20) which is placed in the body part to open and close the opening, a screen part(30) which is placed in the body part and sprays gas to block air flow through the opening when the door is opened, a sensor part(40) which is placed in the door part and senses the opening and closing of the door part, and a control part which controls the operation of the screen part depending on the sensing results of the senor part. The screen part includes a compression unit and a nozzle unit which injects air compressed by the compression unit to block the opening. |
