Densified biomass in Thailand: Potential, status and problems

Development of an appropriate biomass briquetting technology suitable for production and use in developing countries

“…The R&D strategy has been to reduce both the wear of the screw due to friction and the high power consumption. Any savings in power consumption can then be utilized to increase the throughput capacity of the machine (Bhattacharya et al, 1985).…”

Towards the Promotion of Fuel Briquettes Using Municipal Solid Waste and Residual Biomass in Burundi

“…In a recent study in Burundi (Mizero et al, 2015), it was mentioned that several companies had started producing briquettes from municipal solid waste mixed with other types of waste as binders or to improve energy performance. Moreover, the study of the quality and costs of the fuel briquettes from agricultural and forest biomass has been performed abroad (Bhattacharya et al, 1985;Hamelinck et al, 2005;Stolarki et al, 2013), but not sufficiently in Burundi. Therefore, two hypotheses can be put forward: (a) biofuel briquettes made at Bujumbura do not have the same physicochemical characteristics because the constituent raw materials are different; (b) the calorific value of biofuels can be used as a criterion in comparing the real cost of the briquettes.…”

The Characterization of the Heating Properties of Briquettes of Coal and Rice Husk

“…The mixture was preheated at 400 o C for 30 minutes in an electric muffle furnance and then fused at 950 o C, after fussion, the crucible was allowed to cool and was placed on its side in a 150 cm 3 beaker. HCl was added to neutralize the Na 2 CO 3 and boiled to precipitate the sulphate by treating with BaCl 2 .…”

“…Depending on the material of interest, briquetting can be used to provide fuel source, as a preventive measure to many ecological problem. Certain materials like coal, agricultural waste such as rice husk, corn cob, paper and saw dust can be briquetted to serve as cooking fuel (Bhattacharya, 1985). Furthermore, the presence of sulphur fixation agent otherwise known as desulfurizing agent ensures that most of the sulphur content of the coal is fixed into the ash instead of being liberated into the atmosphere as SO 2 (Somchai et al, 1988).…”

“…A briquette is a block of compressed coal, biomass or charcoal dust that is used as fuel (Grainger et al, 1981). In the production of briquettes, the materials can be compressed without addition of adhesive, while in others adhesive materials called binders are added to assist in holding the particles of the material together depending on the type of raw material used for the production (Bhattacharya, 1985).…”
