“…The results obtained showed that the average higher heating value of the cashew nut shell was found to be 4890.23 kcal/Kg. The result obtained from the laboratory testing of the characterization of the biomass fuel for gasification is found similar to that of the earlier studies carried out [4,[6][7][8].…”

The energy and mass flow of the steam cooking operation of three readily defined small-scale cashew processing industries was studied to estimate the availability of cashew nut shell. The proximate analysis of cashew shell waste was carried out using ASTMD 73–75 method. The calorific value of the cashew shell was carried out using bomb calorimeter (ASTME 711). The thermogravimetric analysis of the cashew shell was carried out using TG-FTIR with 10∘C/minute heating rate. The study revealed that, the small-scale cashew processing industries followed steam-cooking process with average energy consumption accounted to be 2969.7 MJ per 1000 kg of raw cashew seed. The cashew shell waste generated in small-scale cashew processing industries was found to be 67.5% of total weight of cashew seed, which can be utilized as fuel for thermal energy supply. The average higher calorific value of the cashew nut shell was found to be 4890 kcal/kg. The thermogravimetric analysis revealed that 85% weight of cashew nut shell has been degraded at 500∘C and in 13 minutes. The availability and fuel analysis of the cashew shell as a fuel revealed its suitability as a supplementary fuel for thermal application through pyrolysis in the industry.

“…Generally, lingo-cellulosic material has the lignin content in the range of 20–30% (Karunanithy et al, 2012), while vegetable waste had lignin in the range 3.23–4.51%. However, vegetable species and lingo-cellulosic biomass are different: the calorific values were almost in the same range reported in some studies (Bhoi et al, 2006; Pareek et al, 2012; Singh et al, 2007), which might be due to the carbon content.…”

“…Gasification is the conversion of a fuel source into a gaseous product that can be used in heat, power or combined heat and power applications (Ouadi et al, 2013). Studies on gasification of different waste biomass briquettes in an open core downdraft gasifier such as jatropha seed husk briquettes (Singh et al, 2008), crop residue briquettes made from cotton stalk, pigeon pea, sugarcane, baggasse, saw dust briquettes (Pareek et al, 2012), biomass waste briquettes (Singh et al, 2007), groundnut shell briquettes (Bhoi et al, 2006) are a few examples. The open core downdraft gasifier has capability to operate on a wide range of fuels such as smaller sized wood pieces, coconut shell and agro residue briquettes.…”

Vegetables waste is generally utilized through a bioconversion process or disposed of at municipal landfills, dumping sites or dumped on open land, emitting a foul odor and causing health hazards. The presents study deals with an alternative way to utilize solid vegetable waste through a thermochemical route such as briquetting and gasification for its energy recovery and subsequent power generation. Briquettes of 50 mm diameter were produced from four different types of vegetable waste. The bulk density of briquettes produced was increased 10 to 15 times higher than the density of the dried vegetable waste in loose form. The lower heating value (LHV) of the briquettes ranged from 10.26 MJ kg to 16.60 MJ kg depending on the type of vegetable waste. The gasification of the briquettes was carried out in an open core downdraft gasifier, which resulted in syngas with a calorific value of 4.71 MJ Nm at the gasification temperature between 889°C and 1011°C. A spark ignition, internal combustion engine was run on syngas and could generate a maximum load up to 10 kW. The cold gas efficiency and the hot gas efficiency of the gasifier were measured at 74.11% and 79.87%, respectively. Energy recovery from the organic vegetable waste was possible through a thermochemical conversion route such as briquetting and subsequent gasification and recovery of the fuel for small-scale power generation.

Biomass is one of the main renewable energy sources and coupled with carbon dioxide adsorbent material, such as calcium oxide sorbent, it increases the biomass conversion efficiency during gasification. This study aims to investigate the thermal degradation behavior of biomass and biomass/sorbent blends. Thermal stability is the stability of the material to resist change in physical shape as its temperature change. The purpose of this study is to determine the thermal stability and the conversion efficiency of biomass and biomass with sorbent blends. Thermo gravimetric analysis (TGA) was employed to determine the thermal stability of biomass and sorbent mixtures of pine-wood, calcium oxide (CaO), and or magnesium oxide (MgO), which will ultimately determine the gasification characteristics of the blends. A mixture resulted in the highest thermal stability and conversion efficiency compared to others will be the one suitable for gasification.
