Abstract (en)
A cleaner (10) for a boiler wall port (36) used by various instruments, including light or sound wave receiving or emitting devices (44) in which the device is mounted to a wallbox (38) surrounding the port and extending from the boiler wall. The wallbox terminates in a mounting flange (42) spaced from the boiler and to which the device is attached. The device includes a wave guide (46) terminating in a flange (48) attached to the wallbox mounting flange. The cleaner includes a weldment (26) attached to the wallbox mounting flange and an actuator (20) mounted to the weldment. The actuator is coupled to a cutting sleeve (12) disposed within the wallbox and moveable into and out of the boiler wall port. The cutting sleeve is coupled to the actuator by a pair of connecting rods (14) passing through the wallbox mounting flange to insure precise alignment of the cutting sleeve. <IMAGE>
