Properties of wood for combustion analysis

The aim of this paper was to analyze energy-related properties of forestry and agricultural wastes for energy production purposes, and to compare them with fossil fuels. The forestry wastes used were red cedar, Eucalyptus, and Pinus wood shavings. The agricultural wastes analyzed were rice husk, coffee wastes, sugar cane bagasse, maize harvesting wastes, and bamboo cellulose pulp. The forestry wastes presented more suitable properties for bioenergy production than the agricultural wastes. Desirable energetic properties were found for coffee wastes. The opposite was verified for rice husks. Among the biomass studied, coffee wastes presented the highest equivalent in fossil fuel volume and hence may lead to the highest decrease in CO 2 emissions by fossil fuels used in Brazil for steam and heat production. The results suggests that CO 2 benefits can be obtained if bioenergy is generated in the same locale where biomass is produced, avoiding CO 2 cost of logistics and leading to greater end-use efficiency. The present work promotes the widespread use of different lignocellulosic wastes for bioenergy production and gives useful information for the planning and the control of power plants using biomass.

“…Pb high content in the lower altitude (100 meters above sea level) can be ascribed to the proximity of the selected samples to the urban areas and also the pollution and environmental conditions of the region and also the higher concentration of Pb in the soil (Kord et al 2010). The minimum and maximum of Pb content of Ironwood in three altitudes and three samples of radial position varied 0,23 to 0,79 Ppm (Table 2 and 4), which is lower than the pb content in beech wood (0,32-3,67 Ppm at Schwaney site and 0,30-1,51 Ppm at Glindfeld site) for different growth season (April, June, September and October) in Germany (Hagemeyer and Schäfer 1995), and lower than the pb of aspen wood (1,4 Ppm) in USA (Ragland et al 1991). Other mineral content of aspen wood is higher than the studied species (Ragland et al 1991).…”

Persian ironwood (Parrotia persica) is native species from Iran and covers 10,54% of the commercial volume. Its wood structure and its chemical composition are affected by growth conditions. The aim of the study was to assess the variation of mineral content (Ni, Fe, Cu, Zn, Pb, Cd), wood density and chemical properties (cellulose, lignin, ash and extractive) of ironwood in relation to altitude above sea level (100, 500 and 700 meter) and pith distance within stem (near to pith and bark and middle point). In addition was investigate the relationship between mineral content with oven-dried density and chemical properties. Results showed that Cd, Cu, Fe, Ni and Zn content (except Pb concentration) increased by increasing of altitude and decreased along radial position within stem from the pith to the bark. Lignin, ash and extractive content increased by increasing altitudes from 100 to 700 meter while cellulose decreased. Radial position had not significant impact on the chemical properties. There are significant relationships between mineral content-chemical properties and between mineral content-wood density (except Cu -density). Forward stepwise regression showed that ash and lignin content had important role on the variation of all of mineral content except on Cd.
