負荷を軽減することができる。According to the first feature of the present invention, when the combustion gas from below passes through the heat exchange fins, the flow of gas tends to be biased to the left and right sides on the heat exchange fins. Also, due to the linear projecting guides provided at the intermediate positions of the upper and lower stages of the water pipe rows at the left and right ends of the heat exchange fin and the water pipe rows at the left and right ends, it is possible to prevent the water from flowing further in the lateral direction. Therefore, it is possible to prevent one can body portion in the left-right direction of the combustion can body from being unevenly overheated. Also, the combustion gas that rises straight up near the walls of the combustion can near the left and right ends of the heat exchange fins has a relatively low temperature from the beginning, but the combustion gas that rises near the walls of the combustion can from the beginning like this. Is prevented from flowing toward the center of the combustion fins by the linear protrusion guide, and then the temperature rises straight up to suppress the temperature rise on the wall surface of the combustion can body.
Further, the lower portions of the left and right side end portions of the heat exchange fins are formed as bent pieces that extend further below the lowermost water pipe position and are closely arranged with a gap along the inner wall of the combustion can. It is possible to increase the heat receiving area from the combustion gas and reduce the heat load on the wall surface of the heat exchange can body at that portion.
