Abstract
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 (02) extending from a power generation steam boiler to an inlet (01') of a power generation steam turbine (01). The steam pipe (02), of constant inner diameter (d), extends from the boiler side to the inlet (01') of the steam turbine (01), and turns at direction turning portion (e) from a vertical steam pipe (02') to a lateral steam pipe (02") near the inlet (01") of the steam turbine (01). The vertical steam pipe (02') is elongated beyond the direction turning portion (e) to form an elongated portion (02'a) having a lower end (02"a). The direction turning portion (e), including the vertical steam pipe (02') and the lateral steam pipe (02"), and the elongated portion (02'a) are made in an integral unit of forged steel.
