Application of chaotic time series for the characterization and control of fluidization and combustion systems. CRADA final report for CRADA No. ORNL92-0127

PDF Version Also Available for Download.

Description

Oak Ridge National Laboratory and Babcock and Wilcox, a prominent U.S. boiler manufacturer, have collaborated under this CRADA to investigate the application of deterministic chaos theory to improve the performance of fossil fuel boilers. The types of boilers investigated were coal-fired fluidized beds and more conventional pulverized coal systems. The results of this investigation demonstrate that chaotic time series analysis of boiler signals (e.g., pressure, acoustic and/or optical signals) can be used to characterize the combustion dynamics with greater accuracy than is possible with conventional signal analysis. Further, it is expected that these new analysis techniques will lead to a ... continued below

Further, it is expected that these new analysis techniques will lead to a new generation of boiler diagnostics and control technology that can make U.S. industry more competitive in the world boiler market. Babcock and Wilcox is initiating follow-on internal and external research to further develop the technology.
