Gasification Applicability of Korean Municipal Waste Derived Solid Fuel: A Comparative Study

Abstract

Gaining energy independence by utilizing new and renewable energy resources has become imperative for Korea. Energy recovery from Korean municipal solid waste (MSW) could be a promising option to resolve the issue, as Korean MSW is highly recyclable due to its systematic separation, collection and volume-based waste disposal system. In this study, gasification experiments were conducted on Korean municipal waste-derived solid fuel (SRF) using a fixed bed reactor by varying the equivalence ratio (ER) to assess the viability of syngas production. Experiments were also conducted on coal and biomass under similar conditions to compare the experimental results, as the gasification applicability of coal and biomass are long-established. Experimental results showed that Korean SRF could be used to recover energy in form of syngas. In particular, 50.94% cold gas efficiency and 54.66% carbon conversion ratio with a lower heating value of 12.57 MJ/Nm3 can be achieved by gasifying the SRF at 0.4 ER and 900 °C. However, compared to coal and biomass, the syngas efficiency of Korean SRF was less, which can be resolved by operating the gasification processes at high temperatures. If proper research and development activities are conducted on Korean SRF, it could be a good substitute for fossil fuels in the future.

Determination of Energy Parameters and Their Variability between Varieties of Fodder and Turf Grasses

“…Additionally, for comparative purposes on the ternary chart, other types of fuels were included, collected from [39], to visualize the composition of proximate components in other types of fuels. Component dispersion was compared to conventional fuels-Spanish Alcorisa lignite [40], Polish bituminous coal [41], Australian bituminous coal [42], Chilean sub-bituminous coal [40]; biomass fuels-waste wood [43], sawdust [43], pinewood [44]; and waste fuels-mixed food waste [45], solid recovered fuel [46] and mixed plastic waste [47]. statistical analysis, it is possible to group species according to proximate content, but it should be noted that only three varieties stand out from the rest-these are characterized by especially high (Perennial Ryegrass var.…”

Revisión de mecanismos de valorización energética para residuos sólidos urbanos caso: relleno sanitario Doña Juana

“…Los residuos sólidos urbanos, al tener elevadas cantidades de materia orgánica son implementados como biomasa en los procesos de producción de energía dado su alto poder calorífico y energético para procesos de transformación (Usmani et al, 2020), se estima que por cada tonelada de residuos sólidos urbanos se puede producir un poder calorífico de 10 MJ/kg por lo que es viable implementarlos como fuente de energía (Malinauskaite et al, 2017). Para la obtención de energía a partir de los residuos sólidos urbanos se aplican diferentes tecnologías como lo son los procesos termoquímicos y biológicos (Lee et al, 2020).…”
