。 The annular upper header 1 and lower header 2 are connected by a large number of water pipes, and these water pipes form two rows of annular water pipe rows 3 and 4 spaced apart in the radial direction. A combustion chamber 7 is formed in the inner and outer water tube rows 3 and 4, an annular combustion gas passage 5 is formed between the inner and outer water tube rows 3, a combustion chamber opening 9 that communicates with the combustion gas passage 5 is provided in the inner water tube row 3, and a combustion chamber opening 9 that communicates with the combustion gas passage 5 is provided in the inner water tube row 3. The water tube row 4 on the other side is provided with a combustion gas passage opening 10 communicating with the flue 11, and flat horizontal fins 12 are arranged parallel to each other on the outer surface of the water tube on the side of the combustion gas passage 5 in the tube axis direction. In a multi-tube once-through boiler with a multi-stage configuration,
The required number of water pipes located on the left and right sides of the combustion chamber opening 9 are used as horizontal finless water pipes 13, and the gap A in the combustion gas passage portion including these horizontal finless water pipes 13 is used as the gap in the other combustion gas passage portions. A heat transfer surface structure for a multi-tubular once-through boiler, characterized in that the gap A in the combustion gas passage portion is gradually reduced as the distance from the combustion chamber opening 9 increases.
