Soot & Scale Affects Boiler Performance | Goodw

2019-7-24·Soot and scale are removed by vacuuming, or by water flow, with watertube boilers. For severely scaled tubes, equipment is available that rotates a flexible shaft with a cleaning tool and vacuum (or water flow) attachment through the tubes. Every boiler cleaning program should include regular efficiency testing.

EC: Lesson 11. Scale and sludge formation in boile

Scales are hard deposits, which stick very firmly to the inner surfaces of the boiler. Scales are difficult to remove, even with the help of hammer and chisel. Scales are the main source of troubles. Formation of scales may be due to; (1) Decomposition of calcium bicarbonate which can be removed by blow-down operation, or (b) to convert
