Thermodynamics Simulation Performance of Rice Husk Combustion with a Realistic Decomposition Approach on the Devolatilization Stage

The high calorific value of rice husk and rich silica content in ash make its valorization becomes attractive. This study presents the thermodynamics simulation performance combustion using a realistic decomposition approach. A non-ideal gas approach fugacity coefficient were also considered calculation. In this study, devolatilization is simulated to form (64.78%), liquid/tar (7.28%), solid/char (27.94%), all these are then oxidized with 100% excess air flue gas. From calculation, about 2.6 MJ/kg specific energy produced. maximum temperature furnace up 1457 °C for perfect insulation 1400 if there 5% heat loss due radiation. Furthermore, expressed that NOX emission amount from negligible still probability CO H2 be produced at above 500 Boudouard reaction homogeneous water shift (WGSR). It found equipped larger could quench reduce efficiency but maintain 700 °C. Supplying 180–200% advantageous keep avoid crystalline formation which harms human health, as well suppressing reducing simultaneous Boudouard-WGSR. Finally, concluded predict reasonable logical results.Graphical Abstract
