This study discusses the lab-scale combustion results of complex waste-derived fuel mixtures in different forms, highlighting that low-moisture mixtures based on municipal solid waste are the most effective in increasing the rate of oxidation reaction and reducing the temperature threshold.
The paper discusses the results of lab-scale combustion of complex waste-derived fuel mixtures in different forms. Composite fuels based on a combination of widespread industrial and municipal waste were considered. The scientific and practical novelty of this study comes from the fact that for the first time, a group of integral parameters was researched. They describe the ignition and combustion of mixtures in different forms: pressed dry fuel (pellets), a wet slurry, and granules of different moisture content. The most efficient method in terms of increasing the rate and reducing the temperature threshold of the oxidation reaction is firing a low-moisture mixture based on municipal solid waste (with a predominance of wood components). Pelleted coal sludge combustion was characterized by a rather long delay in heterogeneous ignition and underburning. It was shown that in order to reduce emissions and increase the degree of burnout, coal processing waste should be burned as wet granules or slurry droplets.
