Pellet stoves arouse a real interest from consumers because they are perceived as a renewable and carbon neutral energy. However, wood combustion can contribute significantly to air pollution, in particular through the emission of particulate matter (PM). In this article, five brands of wood pellets were burnt under optimal combustion conditions an...

... In certain frequencies and exposures, the accumulation of these particulates harm to lungs. Some researchers attribute these particulate emissions to the burning process of biomass fuels [13][14][15]. ...
The potential of near infrared spectroscopy in conjunction with chemometric techniques to predict the particulate matter and gaseous emissions of biomass pellet blends was assessed in this study. A diverse range of biomass was used including wood, Miscanthus, wheat straw and the herbaceous energy grass Szarvasi-1 (Elymus elongatus subsp. ponticus cv. Szarvasi-1). The particulate matter emissions were predicted with root mean square errors of prediction (RMSEP) of 6.83 (R2 = 0.57), 8.71 (R2 = 0.66) and 11.25 (R2 = 0.65) mg m-3 for the PM10, PM0 and TSP emissions, respectively. The gaseous emissions of oxides of nitrogen (NOx), sulphur dioxide (SO2) and carbon monoxide (CO) were predicted with RMSEPs of 14.28 (R2 = 0.93), 4.59 (R2 = 0.88) and 9.08 (R2 = 0.48) mg m-3, respectively. No significant models could be developed for the PM2.5 or PM1 emissions. The results indicate that near infrared spectroscopy has the potential to predict the emissions of biomass pellets in a multi-biomass stream.
