This research systematically evaluates a biomass combustion furnace, focusing on the influence of varying combustion chamber casing materials. The study employs controlled laboratory experiments to investigate the impact of different casing materials on combustion performance, thermal efficiency, and practical applications such as water boiling capacity. The research uses distinct materials, including clay, steel, and aluminum, for combustion chamber casings while maintaining consistent dimensions. The central experimental apparatus, an aluminum stove, was meticulously crafted, adhering to precise measurements. Coconut shell briquettes served as the primary fuel source for this investigation. The results reveal intriguing dynamics in combustion behavior. Notably, the choice of combustion chamber casing material significantly affects fire temperature, sleeve wall temperature, thermal efficiency, and the ability to boil water. Clay emerges as a standout performer, achieving high thermal efficiency (56.8 %), substantial water boiling capacity (25 liters), and efficient fuel consumption (1.28 kg of burnt briquettes). However, steel casing materials excel in generating the highest fire temperatures (up to 557 °C), underscoring their exceptional heat-conducting properties. Aluminum has fast temperature responses but may not retain heat like clay. The findings help optimize biomass combustion furnaces and associated applications. Material selection is crucial to attaining combustion goals like efficiency, temperature generation, or practical heat. These discoveries could lead to more efficient and ecologically friendly biomass combustion systems for sustainable energy and resource use

“…In addition, the kinematic viscosity of biodiesel is within the acceptable range (1.9 to 6.0 mm 2 /s), and the flash point of all biodiesels is more than 150 • C [8,9], which makes it safer than petroleum-based diesel. Furthermore, it was found that mixing different percentages of bio-fuel with ordinary diesel fuel reduces exhaust gases such as carbon monoxide (CO) and particulate manners (PM) [10,11]. However, there is still uncertainty about the ability to reduce the emissions of carbon dioxide (CO 2 ) and nitrogen oxides (NO and NO 2 ) [4,12].…”

The blending of biodiesel with petroleum diesel attracts much attention due to its high potential in reducing emissions. In this work, waste sunflower oil was converted to biodiesel by the trans-esterification method, and it was blended with petroleum diesel in three ratios (10, 30, and 50%). The impact of using these blended fuels in a four-stroke engine on engine performance and exhaust emissions at three engine loads (2, 4, and 6 N.m) was investigated and compared with the use of petroleum diesel and biodiesel. The engine performance was evaluated by determining the brake-specific fuel consumption (BSFC), engine effective power (Ne), brake-specific energy consumption (BSEC), brake thermal efficiency (BTE), and noise intensity. The evaluation of emissions from the engine exhaust was carried out by measuring the levels of carbon oxides (CO and CO2), hydrocarbons (HC), nitrogen oxides (NO and NO2), and particulate matter (PM). The results show that blending diesel with up to 30% biodiesel can reduce CO, HC, and PM emissions by 29.6 ± 1%, 26.0 ± 4%, and 31.0 ± 3%, respectively. However, this decrease is associated with increasing CO2 and NOx emissions by 18.5 ± 2.5% and 29.0 ± 6%, respectively. In addition, the engine showed acceptable performance when using up to 30% biodiesel, where the increase in fuel consumption was limited to 5.8 ± 0.3%. In addition, the engine’s effective power increased with the blending ratio of 10% by 2.0 ± 0.6%, but then decreased with the blending ratio of 30% by only 2.0 ± 0.6%. The noise intensity was also decreased by 2.4%, while BSEC and BTE were reduced by only 2.9 ± 0.9% and 3.5 ± 1%, respectively. The results of this work provide deep insights regarding the utilization of waste sunflower oil as biodiesel to be blended with petroleum diesel, which is a considerable novel approach in the energy and environmental sectors.

“…PCI is the most effective in reducing the use of coke in BF. It is assumed that PC has 75% of carbon, while coke, coke breeze, anthracite, and recarburizer have 85% carbon [11]. A biochar sample derived from wood residues (from combustion at 600-1000 • C) containing 85-87% of C has characteristics similar to coals used in BFs [12].…”

“…Since the properties of the coke mixture require the creation of sufficient load-bearing strength in order to maintain the permeability of the layer, the mixture can be achieved with a maximum of 20% substitution with biochar, reducing CO 2 emissions by 0.33 t CO 2 /t [11].…”

The metallurgical sector is one of the most emission- and energy-intensive industries. The possibility of using fossil carbon substitutes has been investigated to reduce the environmental impact of the steelmaking sector. Among others, biochar emerged as a promising fossil coal/coke substitute. We conducted a literature review on biochar use in the metallurgical sector and its potential environmental benefits. The possibility for biochar as a coal/coke substitute is influenced by the source of biochar production and the process within which it can be used. In general, it has been observed that substitution of biochar ranging from a minimum of 5% to a maximum of 50% (mostly around 20–25%) is possible without affecting, or in some cases improving, the process, in coke making, iron sintering, blast furnaces and electric furnaces application. In some studies, the potential CO2 reduction due to biochar use was estimated, ranging from 5% to about 50%. Despite there still being an area of further investigation, biochar appeared as a promising resource with a variety of uses in the metallurgical sector, contributing to the lowering of the environmental impact of the sector.
