【Abstract】 With the difference between the actual flue gas temperature and rated one in the various heating surfaces of a utility boiler serving as characteristic data a fuzzy pattern identification based model has been set up for energy loss identification. The model can identify three types of energy loss (air leakage, ash deposit caused contamination and the effect of an unscheduled change of coal rank). It should be noted that the effective identification of the three types of energy loss has been realized solely by tracking the change in flue gas temperature at various locations of the boiler.更多还原
