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...
