Effect of the pyrolysis process on the physicochemical and mechanical properties of smokeless fuel briquettes

Study of main combustion characteristics for biomass fuels used in boilers

“…Haykiri-Acma et al [8] used SEM microanalysis to reveal the structural differences between untreated biomass and some of its isolated compounds, such as lignins, celluloses and hemicelluloses. Others, such as Blesa et al [9], used SEM studies, along with other techniques like FT-IR to physically and morphologically characterize carbonized wastes of biomass leading to explain mechanical differences of some materials. Finally Bridgeman et al [10] and Umamaheswaran et al [11] used this technique to determine the particle size distribution of different fuel samples.…”

Agglomeration of low rank Indian coal fines with an organic binder and the thermal behavior of the agglomerate produced: Part I

“…Briquetting of coal has been a widely used technology since last century [6]. As small briquettes are difficult to make and have a low volume, the price of the equipment is high for making of small briquette and all the materials do not have the characteristics that allow them to be agglomerated by pressure.…”

“…In this case, nodulization for making of nodules through a tumblegrowth mechanism is a valuable solution. The agglomeration of coals has been studied using different binding materials like bagasse, molasses, H 3 PO 4 , asphaltite, starch, humic acids, and petroleum bitumen, lignin or a sulfite liquor obtained from pulp and paper mills; woody wastes; and agricultural wastes such as bark, sawdust, beet pulp, and rice husks [6]. Molasses, carboxyl methyl cellulose (CMC), peridur XC3, and peridur C10 as organic binders and cement bentonite as inorganic binder were also used [7].…”

Technical Progress and the Prospect of Low‐Rank Coal Pyrolysis in China

“…The definition of coal pyrolysis refers to a complex physical and chemical change process, in which coal is heated to a high temperature under an inert or no‐air atmosphere . During this process, the rupture of crosslinked bonds in coal, restructuring of the products, and secondary reactions can occur, which yield the following main products: semicoke (50–70 wt %), coal tar (6–25 wt %), and gas (80–200 m 3 t −1 ) . We usually adopt mid–low‐temperature dry distillation to utilize LRC and obtain a higher yield of the aforementioned products.…”
