Characterization of Rice Husk and Coconut Shell Briquette as an Alternative Solid Fuel

Abstract

The physical properties of briquettes made from rice husk and coconut shell in different ratios were evaluated based on their thermo-physical properties. The calculated calorific values of the rice husk and coconuts hell are 16.51 MJ/kg and 18.60 MJ/kg, with densities of 1.50 g/cm3 and 3.00 g/cm3, respectively. Coconut shell has lower moisture and ash content of 10% and 26%, respectively, before briquetting. Comparisons of the experimental and calculated calorific values of the briquettes (17 to 21 MJ/kg) showed that they are in agreement with those of the American Standard of Testing Materials (ASTM) and those reported in the literature. The results further showed that the calorific values of the five briquette ratios were not a function of their moisture and ash contents, rather their total carbon contents. The briquette at the ratio 90:10 of rice husk to coconut shell has the highest calorific value and implies that it has more heating advantages and will therefore be suitable as an alternative solid fuel.

Studi Literatur Karakteristik Briket Dengan Perbedaan Rasio Campuran Arang Tempurung Kelapa Dan Biomassa Lainnya

“…Namun hal ini tidak memiliki hubungan sebab akibat dengan fakta bahwa nilai kadar abu dan kadar air yang lebih rendah disebabkan oleh nilai kalor briket yang lebih tinggi. Menurut penelitian Tanko (2020), nilai kalor yang lebih tinggi disebabkan oleh semakin tingginya kandungan karbon total pada briket [21].…”

The Influence Of Variations In Soaking Time Of Rice Husk Charcoal Briquettes On Its Performance

“…[3] conducted a study on briquettes mixed with rice husk and cabbage waste, producing a calorific value of 4456 cal/gram. [4]analyzed the physical properties of briquettes made from rice husks in different ratios and evaluated their thermophysical properties to produce a heating value of 16.51 MJ/kg. [5] have also researched a mixture of rice husk and coconut shell briquettes, which obtained a calorific value of 4996 kcal/kg at a ratio of 50:50.…”

Effect of two artisanal carbonization methods on the elaboration of charcoal from aguaje (Mauritia flexuosa)seed

“…La densidad aparente de las briquetas producidas estuvo en el rango de 0,470 -0,851 g/cm 3 ; el valor calorífico de las briquetas fue 16,98; 30,07; 32,16 y 25,93 MJ/kg para cáscaras de plátano, desechos de ratán, cáscaras de coco y bagazo de caña de azúcar, respectivamente. Tanko et al (2020) estudiaron las propiedades físicas de briquetas hechas de cáscara de arroz y cáscara de coco, en diferentes proporciones, evaluadas en base a sus propiedades termofísicas. Los valores calóricos calculados de la cáscara de arroz y la cáscara de coco fueron 16,51 MJ/kg y 18,60 MJ/kg, con densidades de 1,50 g/cm 3 y 3,00 g/cm 3 , respectivamente.…”
