“…Araújo et al (2016) showed that when briquettes have a higher bulk density, they also have a higher energy density. The results from the current study can be compared with briquettes of Wang et al (2019) biochar, where a binder was used to form the briquettes, which showed results above 1,006 kg m -3 . Similar values were also found by Teixeira et al (2010), whose study on sugarcane bagasse briquettes determined a minimum density of 910 kg m -³ and a maximum density of 1,330 kg m -³.…”

Boilers are widely used by industries and thermoelectric plants to generate renewable energy. However, when biomass is consumed, residues are generated, which for the most part cannot be discarded appropriately. This study investigated the reuse of eucalyptus wood waste with the goal of transforming the residue into resistant and durable briquettes for reuse in furnaces and boilers. The physico-chemical properties of the residue were studied in terms of chemical composition by X-ray fluorescence, and its crystalline structure was evaluated by X-ray diffraction. Both thermogravimetric analysis and differential thermogravimetric analysis were used to characterize the thermal decomposition of the wood waste residue. The residue was compacted in a universal press with sufficient humidity to fabricate briquettes under different conditions of mechanical pressure. Apparent density, durability, and burning tests were carried out on the briquettes. The maximum temperature reached during burning is dependent on the fabrication compaction pressure. The briquettes proved suitable for burning in boilers and furnaces, and their durability is advantageous for handling, reuse, and transportation.

“…Aliran udara yang masuk ke dalam ruang bakar tersebut membawa kandungan senyawa hidrogen (H) dan okssigen (O), sehingga untuk menentukan laju alirannya juga berdasarkan terhadap kondisi parameter rasio H/C dan O/C. Rasio H/C dan O/C dapat mempengaruhi efisiensi pembakaran bahan bakar, dan mengurangi produk karbon dioksida (CO 2 ), kadar air, dan asap selama proses pembakaran berlangsung [36,37]. Adapun juga, proses pengumpanan bahan bakar briket ke dalam ruang pembakaran menggunakan sistem batch, dimana sistem ini bekerja dengan proses mengumpan bahan bakar dalam satu kali untuk proses pembakaran satu siklus yang dilakukan sama untuk proses berikutnya.…”

The utilization of briquettes as a source of electricity generation is still low due to the briquette characteristics that have high moisture content. This research analyzes the briquette's potential as a source of electrical energy by utilizing its syngas with microturbine gas. The high quality of syngas can be reached by the optimal combustion chamber design. Therefore, the research aim is to be able to design the optimum combustion chamber for the briquette combustion process to generate the syngas. This research method uses two steps, i.e., the design of the combustion chamber and numerical analysis of the briquette combustion process through Computational Fluid Dynamics (CFD) simulations. Numerical analysis of the combustion process using three types of briquettes with different inorganic waste compositions, i.e., K1 type, K2 type, and K3 type. The research results explain the optimum design of the combustion chamber with a total length dimension of 220 mm, an inlet fuel section, and combustion chamber-syngas pipeline diameter of 50 mm and 75 mm, respectively. In addition, the dimensions of the primary air holes are 7 mm, and the secondary air holes are 5 mm. Type K1 briquettes are capable of producing syngas (kg/s) consisting of 6.9x10-13 CO, 3.04x10-31 H2, and 1.8x10-20 CH4. That syngas composition includes in the criteria of syngas in the microturbines gas that produce electric power of 2.3-2.5 kW. The conclusions explain that the combustion chamber can be added to the microturbine gas component, and K1 type briquette can be a solid fuel.

“…Under low-oxygen conditions above 400˚C, crop straw is pyrolyzed, and biochar is produced [17,18]. In recent years, various methods to prepare and utilize biochar from crop straw, e.g., to improve soil, treat sewage, and as fuel, have been explored [19][20][21][22]. Some researchers have begun to modify asphalt with charcoal powder to improve some of the performances of the asphalt binder.…”

The objective of this study is to verify the feasibility of using biochar made from crop straw as a bitumen additive to improve some properties of bitumen. The differences between crop straw biochar prepared in a laboratory and commercial charcoal were investigated through scanning electron microscopy and laser particle size analyses. Furthermore, biochar-modified asphalt was prepared using the high-speed shear method, and the penetration, softening point, ductility at 15°C, and apparent viscosity of the asphalt binder with 6% biochar were measured at 120, 135, 150, 160, and 175°C. It was found that both the crop straw biochar and the commercial charcoal consist mainly of C, O, Si, and K, but the C content of crop straw biochar is slightly higher than that of commercial charcoal. The particle size of biochar is smaller than that of commercial charcoal, while the specific surface area is larger. It was determined that the addition of crop straw biochar significantly improved the high-temperature performance of asphalt, and that biochar and commercial charcoal have a similar influence on the high temperature performance of asphalt.
