Many different methods are used for removing soot from the heat transfer surfaces of boilers.

Steam or air sootblowing and shot cleaning are thgfjgriost common, although the disadvantages and problems are generallyj^he same, whatever method is used.

PROBLEM I.The sootblowing equipment con- sumes a large amount of energy. 11 steam soot- blowing, for instance, between 1% and 8% of the steam generated by the boiler, is used for soot-

Wowing (varies with the fuel). So the operating costs are often high. ,

PROBLEM 2?. Conventional sootblowing meth- ods are periodic. The boiler efficiency therefore gradually deteriorates between one sootblowing occasion and the nexj;, and the heat transfer-sur- * faces are practicallv never complete!^ clean. •.x • < . ---

PROBLEM 3. The medium used for cleaning im- pinges on the heat transfer surfaces from a pre- determinated direction, so it cannot possibly reach all surfaces of the bqiler. Sonnfc soot will remain —in corners, pockets and cavities--and will impair the efficiency of the boiler. *

PROBLEM 4. Sootblowing causes heavy wear $ of the tube material, and may result iit high maintenance costs and unscheduled stoppages.

The sootblowing equipment also demands con- tinuous maintenance.

But the problems open up opportunities...
