| description | PROBLEM TO BE SOLVED: To provide a manufacturing method of a fin tube type heat exchanger which can use a pipe expansion device for a long period of a life, and improves productivity, and a combustion chamber having the fin tube type heat exchanger.SOLUTION: A manufacturing method of a fin tube type heat exchanger (51) includes a pipe expansion process for inserting a pipe expansion device (100) into a heat transmission pipe (21) which is inserted into a pipe penetration hole (20) of a heat transmission fin (2), and expanding the heat transmission pipe (21). The pipe expansion process has a first process for bringing the pipe expansion device (100) into a pipe-expanded state by expanding the heat expansion pipe (21) to a pipe expansion direction in a state that the pipe expansion device is stopped within a prescribed pipe expansion-scheduled range (22) in the heat transmission pipe (21), and makes the pipe expansion-scheduled range (22) adhere to the pipe penetration hole (20), and a second process for releasing the expansion of the pipe expansion device (100) to the pipe expansion direction, and moving the pipe expansion device (100) to a succeeding pipe expansion-scheduled range (22) in the heat transmission pipe (21). The manufacturing method repeatedly and alternately performs the first process and the second process.SELECTED DRAWING: Figure 4
