“…Various reactors and processes have been developed for pyrolysis of biomass from sources such as wood and algae. These include the bubbling fluidized-bed reactor [29], circulating fluidized-bed reactor [30], filtration combustion reactor [31][32], and hybrid filtration combustion reactor [33]. Numerous studies have utilized TGA to analyze gasification and pyrolysis processes Algae, found in aquatic habitats, are part of the plant kingdom and conduct photosynthesis with the help of chlorophyll.…”

In the present paper, the case of the brown algae Saccharina japonica from Aniva Bay (Sea of Okhotsk, Sakhalin Island) was investigated by a thermogravimetric analysis up to 700°C at different atmospheres. The elemental composition, lower heating value, ash content, and biochar yield of the algae were examined. The analysis showed that carbohydrates like alginate, mannitol, fucoidan, and laminarin were decomposed between 250-350°C, while proteins and lipids were burned out between 500-550°C.

“…Research is being carried out for future commercial applications with stationary combustion power plants. Experiments with oxy-circulating fluidizedbed combustion and fluidized-bed oxy-circulating were carried out to facilitate the reduction of O2 supply requirements (Ju Kim et al, 2023). While in a different study, combustion experiments in the FBC combustion chamber were carried out to investigate the effect of oxidant staging and the addition of limestone on reducing NO, N2O, and SO2 emissions that circulate 25% oxy and 31% oxygen input (Baek et al, 2022;Liu, Zhong, Yu, & Wang, 2022;Rahman et al, 2019).…”

The conversion of solid biomass waste into energy continues to be developed at this time to reduce dependence on fossil energy. Energy conversion can be carried out using several technologies commercialized by several industries, including the fluidized-bed combustor (FBC). This FBC technology has also been developed in several ways, such as the modification or unique modelling. In particular, the perforated plate modelling applied in this study is to provide excess air supply so that complete combustion can be achieved. In addition, modifying the perforated plate increases efficiency and radiation and reduces heat loss in the FBC combustion chamber. This research was conducted with combustion experiments using palm kernel shell (PKS), oil palm midrib (OPM), and empty fruit bunches (EFB) against different plates. Experimental results show that the maximum temperature achieved on the modified four guide plates is 975 o C for PKS fuel, 850 o C OPM, and 883 o C EFB with 20% -70% excess air. The results of the highest furnace efficiency on the four guide plate modifications were 91.44% PKS, 73.48% OPM, and 77.63% EFB. Meanwhile, the highest efficiency recorded from modifying the four guide plates for each fuel was 84% PKS, 73% OPM and 74% EFB. The highest radiation rates were recorded at 7745.21 W/sec PKS, 5971.17 W/sec OPM, and 6356.12 W/sec EFB. The perforated plate modification applied in the FBC combustion chamber can reduce heat loss significantly compared to when implementing standard plates.
