Effects of Minerals on Sewage Sludge Smoldering Combustion: Kinetics, Propagation Behaviors, and Product Characteristics

Smoldering combustion technology offers a promising low-energy alternative for the large-scale reduction of sewage sludge. While optimal process conditions for smoldering combustion of sewage sludge have been explored, the influence of fuel properties, particularly minerals, remains unclear. This st...
