A boiler scale collecting device enables collecting and recovery of most boiler scale particulates (p) in a steam flow line (f) in a steam pipe (,) extending from a power generation steam boiler to an inlet (,&prime;) of a power generation steam turbine (,). The steam pipe (,), of constant inner diameter (d), extends from the boiler side to the inlet (,&prime;) of the steam turbine (,), and turns at direction turning portion (e) from a vertical steam pipe (,&prime;) to a lateral steam pipe (,&Prime;) near the inlet (,&Prime;) of the steam turbine (,). The vertical steam pipe (,&prime;) is elongated beyond the direction turning portion (e) to form an elongated portion (,) having a lower end (,). The direction turning portion (e), including the vertical steam pipe (,&prime;) and the lateral steam pipe (,&Prime;), and the elongated portion (,) are made in an integral unit of forged steel.
