“…Hal ini kemungkinan disebabkan karena terjadi jumlah konsumsi karbon (C) pada reaksi pembakaran (water-gas) (Persamaan-7-10), hal ini terlihat dari semakin besarnya kadar syngas yang terbentuk. Hasil ini sejalan dengan hasil penelitian sebelumnya, dimana terjadi perubahan karbon menjadi produk yang semakin besar dengan bertambahnya suhu pembakaran gasifikasi pada tipe downdraft (Long et al, 2020). Dari hasil penelitian terlihat bahwa terjadi peningkatan nilai FC dari 71% hingga 74%.…”

Indonesia is currently experiencing the problem of Municipal Solid Waste (MSW), energy and environmental crisis. Gasification by electric generator is the solution. This study about the design and characterization of the gasification reactor with MSW feed. This research was conducted by examining the effect of gasification temperature (550, 600, 650, 700, 750, 800, 850oC) and Air Fuel Ratio variations (0,5; 0,51; 0,53; 0,54; and 0,55). The variabel tes of temperature variations is syngas, FC, CGE,CCE, and scf. The AFR evaluated syngas and SCF. The result showed an increase the syngas levels with the increasing the gasification temperature, except CO2. The FC value increased(71% to 74%) and The CGE increases (77 to 97%). The CCE increases from 69% to 78% (550-650oC) and decreases again to 66% (850oC), and Scf decreased (4.5-0.5 kg/kWh). In the AFR variation, syngas levels increase with increasing AFR, but scf decreased (5.3 to 2).

“…The coal is fed into the gasifier, and after a short residence time, the organic matter is rapidly pyrolyzed to produce syngas, and the inorganic components melt to form slag 3–5 . The slag then passes along the furnace wall through the cooling chamber into the slag pool 6,7 . In general, the operating temperature is higher than when the inorganic components entirely melt (flow temperature, FT) 8–11 .…”

Iron compounds addition on the melt is a more complex issue. Uncertainties in industrial applications are caused by crystallization and depolymerization phenomena. Most of the current studies have discussed FeO and Fe2O3, ignoring the influence of FeS in the glass structure. This study designed and simulated artificial ash close to coal ash to interact with the glass melt at high temperatures. Coulomb titration, X‐ray diffraction (XRD), and Raman analyses were carried out to determine the percentage and composition of crystalline and noncrystalline materials in the glass. Samples of FeS‐Fe2O3 were subjected to the enumeration of the glass structure and quantitative calculations of the degree of polymerization. The results showed that 15‐wt% Fe2O3 promoted crystallization in the system and accelerates the depolymerization of FeS. The introduction of FeS increases the amorphous materials, and the obtained amorphous materials are Si dominated network structures and [SiO4]‐[FeO4]‐[SiO4] clusters. The network tends to change from [FeOn] and [AlO4] to [SiO4]. In addition, aluminosilicate may enter FeS particles and unreacted FeS may deposit on the aluminosilicate surface.
