The purpose of all boilers, especially the popular fire-tube and water-tube boilers, is to heat water (or other liquids) to very high temperatures in order to produce steam. Steam (a dry gas) is used for a variety of things - power generation, sanitation, central heating, cooking, etc. Evidently, this is a rather lengthy process which takes hours and hours to complete - and is not without imperfections.A plant can be cleaned offline, which requires a planned outage, or online, which can occur while it is still running.
Following Are the Methods Of Cleaning Boiler Tube. Acoustic cleaning With an acoustic cleaning system, ash can be knocked off boiler tubes or selective catalytic reduction systems without causing any damage or fatigue to the unit. It is possible to retrofit acoustic horns onto boilers, but Advanced Acoustic Technologies LLC uses a method designed specifically for plants. In contrast to other horn suppliers, Robert van Dam, AAT's co-founder, explained that their acoustic devices are an engineered, integrated system whose frequency is determined by a 3D element model. The process is similar to flow modelling, except that the company examines how sound waves behave in enclosures.
Cleaning Tubes with Water It runs at over 1200 gallons per minute to flush out any slag buildup. By using a high-volume, high-power hydro blast device, it is able to remove dirt and debris from tubes up to 40 feet long. However, not all systems are able to handle the pressure. Soot blowers A dust blower uses compressed air, steam, or water to prevent slag buildup without the need to shut down the plant. While soot blowers have been around for a while, they are becoming more sophisticated as time goes on, like many other aspects of power plants. There is a basic technology and an advanced technology, which we call SmartClean, said Tim Martin, the director of product management for the boiler efficiency product division at Clyde Bergemann Power Group Americas.
