|  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.
