The recirculation of boiler tail gas with a low oxygen concentration can reduce NOx emissions. Experiments on bitumite combustion were carried out using simultaneous TG/FTIR dynamic runs with different atmospheric compositions, 2%, 6%, 10%, and 12% O-2. Reducing oxygen concentrations led to the burnout temperature shifting to higher temperature and coal combustion becoming more challenging. The reducing gas (CO, CH4) emissions were abundant between 330 degrees C and 690 degrees C. However, along with the reduction in oxygen, CH4 intensity increased, while the CO precipitation peak lowered. Kinetic parameters were defined using the Coats-Redfern model. According to the data obtained, bitumite combustion activation energy increased as oxygen concentration increased. (C) 2017 Energy Institute. Published by Elsevier Ltd. All rights reserved.
