A pipe snow removal device is supported for movement longitudinally along a pipe to clear snow and/or ice from the pipe. A main housing has boundary walls defining an outer boundary of a bounded space within a hollow interior of the main housing. An inner boundary of the bounded space is open to the pipe upon which the main housing is supported. A mounting arrangement supports the main housing relative to a work vehicle that is movable alongside the pipe to displace the main housing along the pipe. A heater heats the bounded space to melt the snow/ice on the pipe. A scraper assembly supported in leading relationship to the main housing clears loose snow before melting remaining snow and ice on the pipe as the housing passes.

The invention relates to a washing machine for longitudinal profiled sections (5), comprising a drum (1, 2) that can be rotated about a horizontal rotational axis (10, 11) and comprises a plurality of receiving areas (101, 102, 103, 104, 105, 106, 107, 108, 109 or 200, 201, 202, 203, 204, 205, 206, 207, 208, 209, 210) which are arranged along the circumference of the drum, which are laterally delimited by lamellas (3, 4), which are open in the radial direction, and into which the longitudinal profiled sections (5) can be inserted along the longitudinal direction (L).

A system capable of autonomous operation is disclosed for cleaning a tube bundle of a heat exchanger core. The system comprises a lance for directing a jet of fluid into spaces between the tubes of the bundle, a carriage for advancing the lance into the bundle, a mount movable relative to the carriage for holding the lance, and a sensor for detecting relative movement between the lance and the carriage, so as to detect when a reaction force acting on the lance upon encountering an obstruction in the tube bundle exceeds a predetermined limit.

Systems and methods for cleaning a heat recovery steam generator system including tubes and fins associated therewith using deep cleaning alignment equipment are described. The deep cleaning alignment equipment primarily includes at least one wedge and at least one wand. The wedge may be an elongate wedge configured to maximize the surface area that contacts the tubes and fins, which in turn minimizes the amount of stress about any specific point of the tubes or the fins. Additionally, the wedge may be made of a variety of different materials. The wedge may include multiple pieces that can be releasably secured together. The wedge may also have at least one opening formed therein to assist in removal of the wedge from the system.

An embodiment provides a method for cleaning a surface, including: encapsulating a cleaning composition in a polymer material to form a compound, wherein the polymer material surrounds the cleaning composition; placing the compound in a location adjacent to the surface, wherein the location adjacent to the surface is a volume separated from an outer volume; dissolving the polymer material at a pH above a target value above the polymer material pH dissolution point, wherein the dissolving releases the cleaning composition; and cleaning the surface using the released cleaning composition. Other aspects are described and claimed.

A washing and doping mechanism includes a bushing that is configured to engage a tubular that is in a substantially vertical orientation. The bushing is configured to rotate, thereby causing the tubular to rotate about a central longitudinal axis of the tubular. The washing and doping mechanism also includes a sprayer configured to spray a fluid onto the tubular in the substantially vertical orientation.

A pipe washing and drying system includes a ring structure defining a radially inner surface and a radially outer surface, the ring structure having a first portion and a second portion hingedly coupled to the first portion. The ring structure further comprises nozzles and rollers defined in the radially inner surface and extending radially inward. The pipe washing and drying system may further include a tent structure comprising a frame and a protective covering supported thereby. The tent frame is coupled between two of the ring structures such that the protective covering covers a section of the pipe between the two ring structures.

Disclosed is a device and method for cleaning a steam wand of a beverage brewing apparatus. The device includes a first reservoir, a larger elastically deformable reservoir, a scrubbing means, a first one-way valve, and a second one-way valve. The first reservoir is adapted to closely encapsulate the steam wand. The first reservoir is open at one end to receive the steam wand. The larger elastically deformable reservoir is adapted to contain a larger sterile portion of a cleaning solution. The scrubbing means adapted to mechanically loosen milk residue through a scrubbing action. The first one-way valve is operable to connect the larger elastically deformable reservoir to the first reservoir. The second one-way valve is operable to allow air to flow into the larger elastically deformable reservoir.

A cleaning apparatus for cleaning a cooling tube array (15) of a heat exchanger has a nozzle carriage (16) movably held on a truss beam, and a plurality of cleaning nozzles (40) mounted to the nozzle carriage. A truss beam has two parallel C-channel rails (20) having back sides that face each other, a tube (22) arranged separate and distant from the C-channel rails and at a different height than the C-channel rails in a cross-sectional plane of the truss beam, and truss supports (24) connecting the rails and the tube; the nozzle carriage has rollers (48) that are arranged for travelling in the C-channel rails. A water intake (82) is coupled to the nozzle manifold (42) and to a hydraulic drive (80) having a mechanical power take-off member (96) that is operably coupled to the nozzle carriage (16) for moving the nozzle carriage.

A laser cleaning system including a laser source, an energy-transferring optical fiber, a laser cleaning head, a coreless motor, a connection lens barrel, and a mirror.
