PROBLEM TO BE SOLVED: To provide a boiler device which can prevent alkaline corrosion on the basis of a structure of piping, a connecting structure and high-temperature measures.SOLUTION: A drain pipe 21 for discharging waste water from a pipe header is arranged in the boiler device having the pipe header 20a connected to an evaporation pipe arranged in a furnace. A gradient part 21b for progressing the discharge of water in the drain pipe and a relay pipe 22 are arranged in the drain pipe. The gradient part and the relay pipe are arranged so as to be descended and inclined from the pipe header. Furthermore, the gradient part and the relay pipe are formed so as to be connected to each other without forming a step. |
