PURPOSE: A steam boiler using firewood is provided to effectively transmit combustion heat by maintaining high thermal conductivity. CONSTITUTION: A steam boiler using firewood comprises an outer body and a fuel placing part(30). The outer body comprises a combustion chamber(10), a heat exchange chamber(20), an ash collecting chamber(40), a combustion chamber door(11), a heat exchange chamber door(21), and an ash collecting door(41). Firewood fuel(200) is burned in the combustion chamber. The heat exchange chamber comprises a flue(22) connected to the top of the combustion chamber and a plurality of vertical pipes(23) installed around the flue. The ash collecting chamber is located under the combustion chamber in order to collect ashes. The combustion chamber door, the heat exchange chamber door, and the ash collecting door are opened and closed on the front sides of the combustion chamber, the heat exchange chamber, and the ash collecting chamber, respectively. The fuel placing part comprises pipes which are arranged at regular intervals to form separate spaces. |
