Zusammenfassung:PROBLEM TO BE SOLVED: To develop the fin shape which makes it possible to improve the heat absorbing efficiency without disturbing the flow of combustion gas in a boiler that the gas flows in parallel with a water tube axis. SOLUTION: The boiler has a combustion gas passage 6 formed of many water tubes 1 for coupling an upper header to a lower header to feed the gas in parallel with a water tube axis, and heat absorbing fins provided on the surfaces of the tubes at the passage side, and comprises quadrangular prismatic fins 12 radially protruding perpendicularly to the axis toward the passage 6 and provided at the tubes 1.
