ANALYSIS OF DYNAMIC BOILER MEASUREMENTS - A PRACTICAL APPROACH

Driven by economic pressures and government emissions regulations, the electric power industry is moving toward tighter control of boilers t o improve plant efficiency and reduce emissions. Tighter control depen ds on better boiler diagnostic tools, especially for discriminating dy namic patterns and correlating those patterns with overall performance . Our research indicates that improved discrimination of dynamic patte rns in boilers can be achieved by combining traditional data analysis techniques and chaotic time series analysis. Suggested analysis tools and data acquisition procedures are described, along with example resu lts for measurements from a pressurized fluidized bed and a low-NOx pu lverized coal boiler.
