Claims

[Claims for Utility Model Registration] 1. Has a ring-shaped upper header 1 and a ring-shaped lower header 2, and connects these headers with a vertical water pipe 3,
5 connects the inner and outer rows of water pipes in a cylindrical shape to communicate with each other, plate-shaped fins 4 are installed between the water pipes 3 of the adjacent inner row, and plate-shaped fins 4 are installed between the water pipes 5 of the adjacent outer row. shape fin 6
Attach the inner row of water pipes 3 and plate-shaped fins 4.
The inside of the combustion chamber 7 is defined as a combustion chamber 7, and a gas passage 8 is provided between the inner row of water pipes 3 and plate-like fins 4 and the outer row of water pipes 5 and plate-like fins 6 for flowing combustion gas approximately at right angles to the water pipes. A multi-tube once-through boiler characterized in that the plate-shaped fins 4 installed between the water tubes 3 in adjacent inner rows are installed closer to the center of the combustion chamber than between the centers of the water tubes 3. Once-through boiler. 2. The multi-tube once-through boiler according to claim 1, wherein the plate-shaped fins 6 installed between the water tubes 5 in adjacent outer rows are installed at a position farther from the center of the combustion chamber than between the centers of the water tubes 5. 3. Instead of installing the plate-shaped fins 4 between the water pipes 3 in the adjacent inner row closer to the center of the combustion chamber than between the centers of the water pipes 3, a plate is installed between the water pipes 5 in the adjacent outer row. 2. The multi-tube once-through boiler according to claim 1, wherein the shaped fins (6) are attached at a position farther from the center of the combustion chamber than between the centers of the water tubes (5).
