High ash content and low fusion temperature are the major bottlenecks in combustion and gasification of Indian coals. Inspired by the MILD combustion systems used for gaseous fuels, a reactor has been designed and developed in our lab for combustion and gasification of Indian coals. This configuration offers the following advantages - (1) stable primary flame even with low grade coal, (2) near homogeneous temperature distribution, and (3) modularity and easy scale up. The near homogeneous temperature distribution is achieved by creating an intense recirculation zone, like in MILD systems, using asymmetrical high speed secondary jets. The primary axial air carries the coal into the reactor. The reactor temperature can always be maintained lower than the fusion temperature by varying the ratio of primary to secondary air. Auxiliary systems are available for crushing, seiving and feeding of coal.
