摘要：
The devolatilization characteristics of single coal particles were studied experimentally for both combustion in air and pyrolysis in nitrogen. The rate constant in volatile matter combustion was 2-3 times larger than that in volatile manner pyrolysis. The weight loss during the devolatilization in nitrogen gas agreed with the value of proximate analysis. However, in the case of coal combustion, the weight loss during the volatile matter combustion region exceeded the proximate value because the particle temperature became high compared with the surrounding gas temperature.
