Fuel Interchangeability Effects on a Scaled Industrial Boiler

摘要

In this study a 400 MBTU/hr industrial boiler operates on various mixtures of natural gas and propane using optimization and control techniques to complete three objectives: minimize NO_x emissions, maintain flame stability, and maximize overall system efficiency. Sensors have been selected based on their ability to characterize one of the four required observation categories: fuel properties, flame stability, emissions, and efficiency. Preliminary data has been conducted that maps the various performance indices for this burner over its set operation range. This paper outlines the research done thus far to achieve the preliminary burner performance data and no details into specific optimization techniques will be discussed.
