In the case of sandblasting, the abrasive material is carefully matched with the particular impurity and surface to be cleaned. In the case of blast cleaning, we generate blast waves with precisely controlled explosive charges, for example, in the combustion chambers of industrial boilers or modern fluidised bed boilers. In this way, it is possible to remove and crush large quantities of deposits in a short amount of time. The effective method can be used in masses at temperatures of up to 1,200 °C. During scheduled downtimes, it can also be used while boilers are cooling.
