Abstract:
The thermal gravimetric analyzer(TGA)and Fourier transform infrared spectrometer(FTIR)were applied to analyze the products of rice straw by oxygen enriched combustion process,and the influence of different oxygen concentration on the combustion process was investigated.Results showed that the oxygen enriched combustion process of rice straw underwent the following stages:moistrelease,decomposition and ignition of volatile matter and char combustion.In the atmosphere of O2-CO2,the char combustion shifted to lower temperatures and got faster complete combustion as the increasing of oxygen concentration,but the combustion characteristics became worse as compared with that in the atmosphere of O2-N2.The major gases released during combustion were CO,CO2 and H2O.The analysis of residues showed that the carbon content in ash would become lower and the combustion was more complete with the increasing of oxygen concentration.
