A Concentration Measurement Method for Flue Gas of Nature Gas Combustion Base on Spectral Analysis
This paper proposed a concentration measurement method for flue gas of nature gas combustion based on the spectral analysis. According to the regression coefficients and prediction errors distribution of partial least squares (PLS) model, the proposed method could finish thewavenumber selection and the outlier spectra detection simultaneously. In order to demonstrate the usefulness of the proposed method, a spectral data of flue gas, which was measured in the combustion process of nature gas, was used in the experiments. Experimental results verify that the proposed method can significantly decrease the number of selected wave number, reduce model complexity and also effectively detect outlier spectra. The established model is more accurate and robust.
