Theoretical Analysis on the Criteria of MILD Coal Combustion

MILD combustion is featured with a uniform heat flux and low NOx emission, and is thus a promising technology for clean coal utilization. Establishing the theoretical criteria of coal combustion modes is essential to guide the design and organization of MILD coal combustion. In this work, different coal combustion modes were classified theoretically based on the analysis of time scale, heterogeneous ignition, heat transfer, and flue gas...
