Hydroblasting vs. Other Boiler Cleaning Techniques

Featured Image

There is usually more than one way to do a job, and combustion-side boiler cleaning is no exception. In fact, the different cleaning methods that contractors use for this task are extremely varied, ranging from the use of explosives in a more brute-force approach to hydroblasting. Each method has its own pros and cons, but our teams focus on hydroblasting because it enjoys some key advantages over the alternatives.


Less Downtime Required Perhaps the biggest benefit of hydroblasting, which causes facility managers to sit up and take notice when informed about its application, is the fact that in most situations, it can accomplish a fireside or gas path boiler cleaning job with little or—incases where there is access—nodowntime at all. If using explosives to blast debris from the external side of boiler tubes, in almost all instances adjacent work must cease and all others must exit the area for safety. Hydroblasting, however, is highly focused and doesn’t pose a risk to those who may be working in the adjacent area. That allows surrounding work to continue, and in many cases, our technicians are able to clean the boiler tubes while it is still operational (again, depending on access, proximity, and other design conditions). Get in and Get Out In our experience, hydroblasting, since it employs a non-toxic, unregulated substance (water!) and is extremely versatile, simply carries fewer complications than other boiler cleaning techniques. You don’t need a permit from the government to hydroblast, whereas obtaining permission to use explosives can be a long, tedious process when time is critical. One more significant advantage of hydroblasting is its precision. Using explosives, by definition, creates strong vibrations and sonic waves that may affect other areas of the boiler and can dislodge scale from within the tubes, thus potentially causing down-stream problems such as eroding turbine blades or steam valve. Addressing those unintended effects can add time and cost to the overall job. Hydroblasting takes place within a clearly defined area and gets the job done as quickly as possible.
