Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a boiler device capable of downsizing an appearance shape as small as possible. SOLUTION: The boiler device 1 has many heat transfer pipes 4 extending across the flow of high temperature gas, in the flow direction of the high temperature gas inside a duct 3 passing the high temperature gas (high temperature fluid). The boiler device 1 heats heated fluid W introduced into the heat transfer pipes 4 with the high temperature gas via the heat transfer pipes 4 and generates steam of the heated fluid W. The diameter of the heat transfer pipes 4 is set small when they are disposed on the downstream side of the high temperature gas in the duct 3 in response to a condition where heat flux does not exceed a critical heat flux. |
