For further interpreting the devolatilization and the char combustion processes of RDF quantitatively, an unsteady combustion model for single RDF pellet, involving reaction rates, heat transfer and oxygen diffusion in the RDF pellet, was developed. Comparisons of simulation results with experimental data for mass loss of the RDF samples made from municipal solid waste, wood chips and poly propylene when they were heated at 10K/min or put into the furnace under 1?073?K show the verifiability of the model. Using this model, the distributions of the temperature and the reaction ratio along the radius of RDF pellet during the devolatilization process and the char combustion process were presented, and discussion about the inference of heating rate on the combustion characteristics were performed.展开更多

The result shows that the decrement of COD may arrive at 80% by the strengthen effect of Photosynthetic Bacteria. The biochemical methane Potential (BMP) and Chemical Oxygen Demand (COD) of cotton pulp black liquor are also measured during the experiment using improved measure method. The equivalent of COD and BMP is verified as a result. Finally analysis is done based on the experiment result.展开更多
