Investigation of emission of NOx, SO2 and chlorine by biomass-burning

Abstract

It is well known that burning biomass is somewhat CO2 neutral, but it is not widely known that that process is still a serious environment polluting one. For the investigation of the emission of some biomass material such as energy willow, bamboo, energy cane was burnt and the emission of NOx, CO, CO2, SO2, and Chlorine were measured and analysed. The results show that the generation and emission of SO2 observed at the beginning of the burning process, while the chlorine is leaving the fire at the end of the process. The emission of NOx is rather at the middle of the process. The sum of the SO4 2- and the overall chlorine ion are more than those materials in the biomass, indicating that these elements are present in the material in different form.
