Artificial neural network and fuzzy logic based boiler
Feb 20, 1998 · The add hoc technique consists of detection of tube leaks using a so-called expert system approach. A major drawback and disadvantage of this approach is that it lacks universality. That it to say, it can only be used, after an extended time of modification of the design and tuning, to the specific boiler with which the expert person (the

Boiler tube leakage detection expert system - ScienceDirect
The most probable reason for failure in the power plant boiler is tube leakage. It is usually detected when urgent action is needed to prevent accidents in the plant. Advance detection of boiler leakage is of primary interest to secure maintenance planning and prevent the adverse effect of tube rupture. The development of the tube failure detection system is a demanding …

Power industry boiler tube failures are a major cause of utility forced outages in the United States, with approximately 41,000 tube failures occurring every year at a cost of $5 billion a year. Accordingly, early tube leak detection and isolation is highly desirable. Early detection allows scheduling of a repair rather than suffering a forced outage, and significantly increases the …

Optimization of sootblowing frequency to improve boiler
Jan 28, 2015 · In a conventional coal-fired boiler combustion of coal causes buildup of soot, ash, and slag in the heat transfer surfaces, which reduces the heat transfer as well as operating efficiency. To achieve a high operating efficiency and improving heat transfer in boiler pressure parts, sootblowing is an important phenomenon in boiler operation. Boiler operators are …
