Boilers can become scaled with calcium, magnesium, iron, silica, phosphate, and other minerals. These deposit cause poor heat transfer and lower the efficiency of the boiler increasing fuel consumption. The poor heat transfer also leads to elevated flue gas temperatures.

A boiler inspector can fail a boiler due to the amount of scale present. Historically, acid cleanings were the only way to clean the tubes. A risky and very expensive proposition including the handling of hazardous waste.

WES has designed an offline cleaning that is safe to the boiler base metal and can be discharged to the sewer system. The cost is ¼ that of the traditional acid cleanings. A safer, more effective, lower cost alternative. Below are some before and after photos of a recent firetube boiler cleaned with the WES offline cleaning product.
