Special Applications

Our cleaning services include these applications.

Boiler Cleaning

Our boiler furnace cleaning process provides the greatest volume per hose size and pump size, while our unique indexer and head setup reduces cleaning time. We we typically save a shift or more of plant downtime, allowing for faster plant startups. The process also removes material in smelt beds more efficiently than conventional processes.

We offer a process for storage and recirculation of water for locations that must shut down due to wastewater or repair schedules. The ability to continue cleaning in these scenarios reduces plant downtime and increases pump utilization.


Digester Cleaning

USA DeBusk has performed many digester cleaning projects resulting in faster plant startup times.

These projects are typically completed in one shift, where other service providers require multiple shifts.


We service heat exchangers in pre-heaters, cooking liquor heaters, black liquor heaters, black liquor coolers, and more.

Our equipment nozzles and flex lances will clean the middle of the U-bends and return exchangers to near-new status.

We offer chemical cleaning and automation processes for in-situ cleaning of the shell side of exchangers in many applications.

Concentrators and Evaps

Our processes use automated rigid or flex lances to clean up to 6 tubes at once.

Tube cleaning occurs upon both entry and retraction of the lances.

Stripper Columns

For plants with stripper columns, USA DeBusk crews can enter and clean each tray, upper and lower, in less time than conventional methods. The process brings each tray back to original status.

Our cleaning is more efficient, less intrusive, and generates less waste than other processes.

Tank Cleaning

We have multiple methods for cleaning tanks and neutralizing chemicals. Our high pressure/high volume pumps and processes clean tanks to meet customer specifications without harming the tank liner.

While USA DeBusk teams have the training and equipment to make IDLH entry, we also offer automated systems to eliminate confined space entry in hazardous locations.

Washer Drums

Our proprietary automation cleans washer drums and CB Washers.

Automation eliminates manual cleaning, which increases the cleanliness of the drum and reduces equipment downtime.
