Rice husk used as solid fuel for chemical

QC,out for rice husk/charcoal combustion was increased for experiments conducted with higher oxygen carrier flow rate, and reached 722 W as fuel conversion reached 90%. However, QC,out for rice husk and rice husk/sawdust combustion conducted with oxygen carrier flow greater than 22.7 g/min, and reached 283 W and 250 W as fuel conversion reached more than 92% and 92%, as shown in Fig. 10 and Table 2. QC,out for rice husk/charcoal combustion was higher than that R-7128 for rice husk and rice husk/sawdust combustion because more charcoal was increased the heat value of rice husk combustion. As shown in Table 3, 393 W and 349 W were required for rice husk and rice husk/sawdust gasification in the ADMBR, indicating mesophyll roughly 54% of Qin released for both rice husk and rice husk/sawdust gasification in the ADMBR. Moreover, 183 W was released for rice husk/charcoal gasification in the ADMBR, accounting for about 19% of Qin released. More heat was generated for gasification of rice husk and rice husk/sawdust by CO2, probably because higher oxygen content in these fuels might achieve more complete combustion. Moreover, less heat was generated for rice husk/charcoal gasification because higher fixed carbon content present in the fuel, and more heat demand was needed for char gasification.
