Water soot washing

Water soot washing
A water washing devise is normally a number of water nozzles placed over the tubes and the water washes the tubs and the sooty water is then collected in a pit below the exhaust gas boiler.
The water washing system is designed for soot cleaning during non-operation and for fire fighting. The drain from the water collecting pit has to be open before the washing start.

A water washing devise is often installed as a complement to other methods that can be used during boiler operation.

This example is an exhaust gas boiler.
