Abstract: Herein a boiler tube (2) having a longitudinal extension (L) and comprising radially inner and outer tubular portions (4, 6) extending along at least a first part (5) of the longitudinal extension (L). The radially outer tubular portion (6) is metallurgically bonded to the radially inner tubular portion (4). A sensor space (8) is arranged between the radially inner tubular portion (4) and the radially outer tubular portion (6), wherein the sensor space (8) is configured to accommodate a sensor arranged to detect a physical property of the radially outer tubular portion (6). A duct (10) is connected to the sensor space (8) and extends through the radially outer tubular portion (6) to an exit portion (12) of a surface of the radially outer tubular portion (6). The radially inner and outer tubular portions comprise materials of different chemical composition. Also, a boiler tube unit and a furnace are disclosed herein.
