PURPOSE: A horizontal-type boiler of a dual-firebox structure is provided to selectively operate a burner by completely dividing a firebox, thereby enhancing the reliability of control. CONSTITUTION: A horizontal-type boiler of a dual-firebox structure comprises a housing(10), first and second fireboxes(20-1,20-2), first and second burners(30-1,30-2), a heat exchange unit(45), an exhaust port(41), and a water chamber(60). The first and second fire boxes are completely separated from each other. The first and second burners are respectively installed in the first and second fireboxes. The heat exchange unit is installed in the inner upper part of the housing and connected to the first and second fireboxes. The heat exchange unit provides a combustion gas discharge passage and a heat exchange passage. The exhaust port is installed in the upper part of the housing and connected to the heat exchange unit. The exhaust port provides the combustion gas discharge passage. The water chamber surrounds the first and second fireboxes and stores water. |
