“…Also, there are visible smoke emissions during the heating process of raw briquette fuel in comparison with tested torrefied briquette blends. The results obtained for raw 30/70 (CH/SD) briquette ratio is close to the SFC value of 0.175 g L -1 for charcoal obtained in the work of Abasiryu et al [32] and within the range of results obtained for SFC by Oyelaran et al [21].…”

“…For instance, Parmigiani et al [20] used raw rice husk and obtained an average low thermal efficiency (TE) of 18% and high specific fuel consumption (SFC) of 4.2 MJ kg -1 . Oyelaran et al [21] used groundnut shell briquettes at different binder proportions as feedstock and reported an increase in the TE from 14.47 to 18.46%; burning rate (BR) (0.587-0.881 kg h -1 ) and SFC (0.067-0.267 J g -1 ). Furthermore, Rajaseenivasan et al [22] reported that the decrease in neem content on sawdust increased the BR and decreased the SFC and WBT.…”

Agricultural waste management through energy recovery is one of the critical options that could drive the clean energy production industry and properly replace the use of coal in Nigeria if done sustainably. The objective of this work therefore is to study the synergetic effect of waste feedstock mixture and torrefaction pre-treatment on some physical and performance characteristics of briquettes from cornhusk (CH) and sawdust (SD) wastes. In this work, CH and SD wastes were processed raw and torrefied at 200 to 300 °C and were mixed in the ratios between 90/10 and 10/90 for briquette production using D-optimal crossed design. Cassava starch of 20 g to 100 g of the feedstock (w/w) was used as binder. The performance characteristics of CH/SD briquettes were evaluated using standard procedures while the generated data were processed using ANOVA, regression and pareto analysis. The thermal efficiency of 29.94% and water boiling time of 12 min were obtained for CH/SD briquette blend of ratio 10/90 torrefied at 300 °C. The maximum density and water resistance index of the torrefied briquettes at different blends respectively increased between 5.78–9.77% and 75.70–85.45% over those of the raw briquettes due to torrefaction and water preconditioning. Furthermore, the lowest value of burning rate was obtained for briquettes torrefied at 300 °C at 50/50 (CH/SD) ratio. ANOVA revealed that torrefaction and feedstock blending significantly influenced the characteristics of CH/SD briquette at p<0.05. This study showed the potential use of torrefied briquettes from cornhusk and sawdust wastes as alternative for coal and forest wood and a new source of energy for heating applications.

“…The test is known as the Water Boiling Test and it will be used for assessing the briquettes with each other. The modified version of the WBT, which was developed for the Shell Household Energy Programme based on the procedures proposed by VITA and Baldwin was used in this work (Oyelaran et al, 2015). It consists of three phases.…”

Current energy shortage and environmental issues resulting from the use of fossil fuels have led to exploitation of renewable energy resources that includes municipal waste and agricultural residues. These residues are available, indigenous and are environmental friendly but some cannot be used directly in combustion process due high moisture content and low volumetric energy unless by briquetting. The study was undertaken to assess the combustion characteristic of binder-less briquettes produced from waste paper and groundnut shell. Combustion characteristics investigated were ignition time, burning time, calorific values, burning rate, specific fuel consumption, fuel efficiency and water boiling time. The calorific values of the briquettes ranged from 19.51-19.92 MJ/kg, while the thermal efficiency ranges between 13.75-21.64%, other results shows that the average burning rate between 0.511 and 1.133 kg/hr and the specific fuel consumption ranges between 0.087 and 0.131 J/g. The recorded boiling time values were between 17.5 and 30.0 minutes for cold start and 15.0 and 20.0 minutes for hot start. The results shows that waste paper and groundnut shell up to 25% in composition composite briquettes were found to have good combustion characteristics which qualify them as alternative to firewood for domestic and industrial energy. However, production of briquettes from waste paper and groundnut shell at mixing ratio of 85:15 was found to comparatively better from all experiment conducted.

“…The use of wood and agricultural residues for both domestic and industrial fuel has greatly improved thanks to the densification of residue materials. Densification provides a number of benefits, including: (i) improved handling, durability, and transportation, (ii) regulated particle size distribution for improved feedstock uniformity and density, (iii) improved compressive strength, (iv) increase in calorific value, (v) quality of fuel such combustion time, specific fuel consumption and colour flame and (vi) conformance to predetermined alteration technology and supply system requirements [4]- [9]. Briquettes made at lower pressures (10 to 60 MPa) are said to fall apart easily.…”

Densification improves the properties of loose biomass for use as fuels, and the process is a complex technological problem involving the interaction of variables that are interdependent on one another. The effects of process variables (pressure and dwell time) and a material variable (percentage binder, particle size, and mass) on the density of cashew nutshell and cassava binder briquettes were investigated using structural equation modelling (SEM) with the help of AMOS version 23 software. A furnace was used to carbonize cashew nut shells at temperatures of 250°C. The pulverized charcoal from the carbonization process was used to create briquettes with cassava paste as the binding medium. Different particle sizes of 0.5 mm, 1 mm, and 2 mm were used to create briquettes. Different compaction pressures (9.81 MPa, 19.6 MPa, and 29.42 MPa) were used in the absence and presence of various binder ratios (10%, 20% and 30%). SEM analysis found that factors pressure ((Path coefficient (b) = 493), binder percentage (b = 0. 406), mass (b = 0.257) and dwelling time (b = 0. 173) positively influence the density of cashew nutshell and cassava binder briquettes and conversely for particle size (b = - 0.505, C.R = - 6.010). In addition, SEM model showed that a particle size has the strongest effects on the density of the briquettes followed by compacting pressure and thirdly binder percentage. This study provides a better understanding of some of the factors that influence making of briquettes from cashew nutshell and cassava binder.
