Boiler equipment and organic waste treatment system including the same

Boiler equipment comprising:

• a combustion device including a combustion chamber to combust fuel supplied to the combustion device;
• a combustion furnace including a combustion chamber formed inside thereof;
• and
• a heat exchanger transferring thermal energy obtained by combustion of the fuel in the combustion device to water, wherein:
• the combustion device is directly connected to a wall part of the combustion furnace such that the combustion chamber of the combustion device faces the combustion chamber of the combustion furnace;
• the heat exchanger includes:
• a steam-water drum disposed above the combustion chamber of the combustion furnace;
• a water drum disposed at a position higher than an opening part of the wall part of the combustion furnace, the opening part to which the combustion chamber of the combustion device is opened;
• and
• a water tube system in which a first end part thereof is connected to the steam-water drum while a second end part thereof is connected to the water drum at the position of the water drum in a height direction;
• and the water tube system includes:
• a plurality of first water tubes provided on an inner wall surface of the combustion chamber of the combustion furnace so as to extend vertically;
• second water tubes through which water supplied from an outside to the steam-water drum flows downward;
• third water tubes horizontally provided at the position of the water drum in the height direction so as to flow the water that has flowed through the second water tubes to the first water tubes;
• and
• fourth water tubes through which part of the water that has flowed through the third water tubes further flows to the water drum.
