“…The different components of this ICS-G are shown at the diagrams in the figure 3. Calculation of the improved ICS-G stove dimensions takes into account different aspects [32][33][34][35][36]; in particular, the amount of energy needed to cook a meal for a six-persons household was estimated to be around Q = 15.8 MJ [28,[32][33]. Therefore, the minimum power requirement to cook food for a meal for a family of six persons with a burning time in the range 1.0 to 1.5 www.videleaf.com h [34] is about 3 kW.…”

“…Their results showed that the gasifier performance and operating conditions were good and the stove could provide modern energy services for basic needs and productive applications in the rural areas. [84] developed an 11.2 kW laboratory scale updraft gasifier that was tested using sawdust and palm kernel shell (PKS) as feedstock. The gasifier performance for both sawdust and PKS comprised of chemical energy inputs of 28,125 and 31633.06 kJ, power input of 7.81 and 8.79 kW, power output of 5.47 and 6.15 kW and the respective gasifier efficiencies of 93% and 67.4% and would meet various applications of heating, electricity supply and could be used to generate the needed combustible gases during fuel scarcity.…”

Charcoal has found enormous application in both agriculture (AKA biochar) and other sectors. Despite its potential benefits, small scale technologies relevant for its production remain a challenge. Technologies striking a balance between user friendliness, energy efficiency, ease of adaptation and limited emissions could easily be integrated into the local community for the sustainable production of biochar answering both technical and socioeconomic aspects. These technologies can be customized to recover the produced heat alongside biochar and the producer gas. The purpose of this work is to review the state of the art in small scale technologies, their associated risks and challenges as well as research gaps for future work. Factors affecting biochar production have been discussed and temperature is known to heavily influence the biomass to biochar conversion process. Based on the reviewed work, there is a need to develop and promote sustainable and efficient technologies that can be integrated into biochar production systems. There is also further need to develop portable, economically viable technologies that could be integrated into the biochar production process without compromising the quality of produced biochar. Such technologies at midscale level can be channeled into conventional small scale farmer use in order that the farmers can process their own biochar.

“…In updraft, counter current phenomena involve [19], where gasification medium introduced from bottom of grate while biomass from top of reactor. Sequence of process inside reactor is carried out by drying followed by pyrolysis, reduction and combustion, chemistry of reactions is given below [20]. (6) This work focused on determining characteristics of mango seed shell and its utilization as emerging biomass for energy generation via thermochemical conversion, which can benefit domestic and industrial (mainly fruit processing) sector.…”

Waste biomass is gaining increased interest as a feedstock for energetic and non-energetic products. In this study, potential of wasted mango seed shell for bioenergy production by using laboratory scale updraft gasifier was investigated. Gasifier was operated with and without packing at air velocity of 3.0 and 3.5 m/s. Biomass characteristics, temperature profile, influence of air velocity on higher heating value (HHV) of producer gas, composition of gas and thermal efficiency of gasifier were parameters considered for analysis. Operation without packing material showed better performance. Results depict that maximum 3.56 MJ/Nm 3 of producer gas was generated at lower air velocity. Maximum operating time for complete consumption of biomass was recorded as 165 minutes. Negligible difference found in temperature profile between both operating modes. Temperature profile indicated that temperature attained during operation was 372°C, 742 °C, 604 °C and 423 °C for drying, combustion, reduction and pyrolysis zone, respectively. The Proportion of product gas was 75 %, while black thick liquid (mixture of Tar and moisture) and biochar were byproducts contributed about 8% and 10%, respectively. Mango pit shell waste is valuable bioenergy feedstock and its recycling could be economically and environmentally beneficial for mango processing industry.
