CLEANING SOOT FROM INDUSTRIAL BOILERS

An industrial boiler is designed for the best heat exchange between:

the heat of the smoke, and
the fluid in the tubes of the boiler

Of course the temperature is continually decreasing from the kiln of the burner to the outlet .

Soot clogging will result in :

loss of efficiency
decreasing of the area of contact for the gas
decreasing of the gas flow and of the power output of the boiler

Any technical choice is a compromise!

All soot cleaning devices have their advantages and disadvantages… They should be considered as complementary more than in competition with each other!

There are three basic types , based on these principles:

dynamic jets clean the surface hit by the jet
mechanical or acoustical waves avoid deposits on tubes
chemical additives improve burning to modify chemical deposit nature
