PURPOSE: A water discharge structure of a multi-pipe type boiler is provided to enhance the productivity by achieving the discharge purpose of water. CONSTITUTION: A water discharge structure of a multi-pipe type boiler comprises upper headers(12a), and lower headers(12b). The upper headers are arranged on the top of a casing at a certain interval. The lower headers are arranged on the bottom of the casing at a certain interval. A vertical water pipe is connected to the upper headers and the lower headers in a concentric circle form. The upper headers and the lower headers form pipe walls(14a,14b) around a circular combustion gas passage. A combustion chamber is formed in the pipe wall using a circular heat transfer acceleration board. |
