“…The development of such prediction models requires substantial analysis data on melting temperature. Another alternative is the fluidity analysis method, which is relatively simple and easily reproducible; this has been proposed in various studies [8,11,16,[19][20][21][22][23].…”

Solid fuelization technology can increase the heating value of sewage sludge such that it can be utilised as a fossil fuel substitutes. Reducing landfilling of bottom and fly ash resulting from heavy metals contained in sewage sludge is challenging. Hence, combustion melting technology (CMT), which can discharge bottom ash in the form of slag, has been proposed herein as an alternative to the conventional incineration technology. However, further research is required to improve the flowability of slag. Applicability of CMT for the stable treatment of heavy metals in the ash generated during the energisation of sewage sludge solid fuel has been reviewed. The change in the degree of fluidity was identified via a laboratory-scale fluidity measurement experiment following changes in melting temperature, mixing ratio of sewage sludge and sawdust, and basicity. The pouring index (PI) of sewage sludge solid fuel (pellet) was maintained at a level of about 60% at a basicity index of 0.8. Based on the results, the slagging rates and volume reduction rates, exhaust gas analysis, and heavy metal elution characteristics under oxygen enrichment were derived from a 2 ton/day combustion melting pilot plant experiment; thereafter, the feasibility of combustion melting of sewage sludge solid fuel was determined.

“…According to the experiment by Kim et al (2004), MgO did not have a significant effect on slag's viscosity if the amount of Al2O3 was fixed. However, increasing MgO up to 12.5% will enhance the mobility of slag (Logachev et al 2013). Logachev et al (2013) concluded that if the content of MgO increases to 12.5% and the basicity is between 0.94 and 1 the slag mobility could be increased, even with a high content of Al2O3.…”
