摘要

In power plants, stacks are usually not instrumented to measure NOx emissions on a regular basis. Thus the available emission data is always very limited, and often uncertain and imprecise. This makes the modeling for emis- sion reduction by statistical methods extremely difficult. In this work, a novel fuzzy modeling methodology is developed to generate a reliable emission model with only limited data. The model ca be an essential part in environmental dispatching. The efficacy of the model-based dispatching is demonstrated by successfully applying it to the NOx reduction in a power plant that consists of four units sharing only one stack.
