Boiler fouling cases and the online cleaning systems
Each combustion of organic substances produces particles, which are discharged with the flue gas.

This results in a reduction of the heat transfer. These contaminants are removed by means of various cleaning systems. The most important automatic online cleaning methods are described below.
