“…The majority (83.25-88.66%) of rice husk particles were in the range of 0.212-0.850 mm. These values are within the range of 0.1-1 mm reported by Casaca and Costa (2009) for the rice husks from Portugal, the range of 0.075-3 mm reported by Subramanian et al (2011) for the rice husk from India and the range of 0-10 mm reported by Fang et al (2004) for the rice husk from China. However, the particle size range obtained in this study is higher than the range of 0.05-0.3 mm reported by Kuo et al (2011) for the rice husk from Taiwan and lower than the range of 1.40-2.36 mm reported by Mansaray and Ghaly (1997) for the rice husks from Louisiana (USA) and Sierra Leone.…”

“…The moisture content was 4.72% for the long grain rice husk, 5.63% for the short grain rice husk, 4.60% for the cascara de arroz rice husk and 6.07% for the japonica rice husk. These values are lower than the value of 8.1% reported by Subramanian et al (2011) for the rice husk from India, the value of 9.8% reported by Velez et al (2009) for the rice husk from Colombia, the value of 10.7% reported by Zhou et al (2009) for the rice husk from China, the values of 8.68-10.44% reported by Mansaray and Ghaly (1997) for the rice husks from Louisiana (USA) and Sierra Leone and the values of 9.8-10.7% reported by Casaca and Costa (2009) for the rice husks from Portugal. They are, however, higher than the value of 4.2% reported by Kalderis et al (2008) for the rice husk from India.…”

Rice husk and straw are by-products of rice cultivation and processing industry and can be used as an energy source. Proper understanding of the physical properties of rice residues is necessary for utilizing them in thermochemical conversion processes such as gasification and combustion. The physical properties (moisture content, particle size, bulk density and porosity) of rice husks and straws obtained from three countries (Egypt, Cuba and China) were evaluated in this study. The moisture contents of rice husks and straws were in the ranges of 4.60-6.07% and 6.58-6.92%, respectively. For all rice varieties tested, the moisture content of the straws was higher than these of the husks. The particle sizes of rice husks and straws were in the ranges of 0.212-0.850 mm and 0-0.710 mm, respectively. All the rice husk varieties had a normal distribution of particle size around the main value of 0.6 mm while the particle size distribution for the rice straws showed a decreasing trend, the larger the particle size the higher was the weight percentage. The bulk density of rice husks and straws were in the ranges of 331.59-380.54 kg m -3 and 162. 03-194.48 kg m -3 , respectively. The bulk density values of rice straws were lower than those of rice husks. A negative linear relationship between the bulk density and the average particle size was observed for rice husks and straws. The porosity of rice husks and straws were in the ranges of 63.64-68.94% and 71.21-85.28%, respectively. A positive linear relationship between the porosity and the average particle size was observed for rice husks and straws. Also, a negative linear relationship between the porosity and the bulk density was observed. The results obtained from this study showed significant differences in the physical properties of the rice husks and straws collected from different countries (located in three different continents). These differences may be due to variations in climatic conditions, soil type, methods of cultivation and type of fertilizer used. The results also indicated that different parts of rice plant (straw and husk) had different physical properties. Also, significant differences were observed among rice varieties even though they were grown under the same climatic conditions using same soil type and cultivation method as in the case of the long and short grain rice variety of Egypt.

“…Increasingly, there are made attempts to use biomass and other wastes, such as meat or waste tires as reburning fuel [30][31][32][33][34]. The obtained results indicate that a reduction of the NO concentration which can be achieved here is about 70% [34] and even up to 80% [32,33].…”
