The present invention relates to a small fire tube boiler having a work space. The small fire tube boiler having a work space comprises: a flue (10) which is formed in a cylinder shape; a main body (20) of which the inlet is welded to the end of the flue (10) and of which the outlet has left and right groove forming parts (21) in both sides; multiple first fire tubes (30) of which one side is connected to the inlet of the main body (20) and of which the other side is connected to the groove forming part (21) of the main body (20); and multiple second fire tubes (40) of which one and the other sides connect the top ends of the inlet and outlet of the main body (20). Thus, the present invention reduces the whole size of the boiler compared with a conventional boiler by remarkably reducing the size of the flue and prevents damage to the flue caused by heat. |
