Coconut husk, areca nut husk, rice husk, saw dust and there combinations were used for experiment. The average moisture content were 12.09 per cent, 14.65 per cent, 15.09 per cent and 14.86 per cent for coconut husk, areca nut husk, rice husk, and saw dust, respectively. The average bulk density was 76.32 kg/m3, 81.98 kg/m3, 109.66 kg/m3 and 199.84 kg/m3 for coconut husk, areca nut husk, rice husk and saw dust, respectively. The average residue collected were obtained as 12.64 per cent, 10.77 per cent, 11.69 per cent, 48.18 per cent, and 38.43 per cent for T1, T2, T3, T4, and T5, respectively. Biomass was analyzed for temperature and burn in developed burning chamber. The combustion study was carried in burning chamber. 1kg sample, it was observed that the temperature increases from 29.16 to 167.66 °C, 29.46 to 155 °C, 29.53 to 146.3 °C and 30.4 to 143.13 °C for T2, T3, T4 and T5, respectively during 20 min of durations. 2 kg sample, it was observed that the temperature increases from 28.8 to 180.96 °C, 29 to 165.36 °C and 28.5 to 146.43 °C for T2, T3, and T4 respectively during 20 min of durations. But in case of T1 and T2 temperature increases from 29.26 to 232.56 °C and 30.06 to 152.73 °C during 0 to 15 minute of duration, respectively . For combustion of 3 kg sample, it was observed that the temperature increases from 29.5 to 248.96 °C, 29.96 to 227.46 °C, 29.6 to 174.13 °C and 30.73 to 165.8 °C for T2, T3, T4 and T5, respectively during 20 min of duration. But in case of T1 temperature increases from 29.8 to 304.5 °C during 0 to 15 minute. The results indicated that coconut husk and areca nut husk were good for combustion in developed burning chamber. Burning of sawdust and rice husk and there combinations were not suitable for burning in developed burning chamber.Keywords

Wood is one of the earth’s most valuable resources and it conforms to the most varied requirement. There are over 1600 different species of woods which are used for various purposes. Wood shows a remarkably wide range of variation in their properties, timber and the type of end use (Rajput and Shukla, 1996). Wood is a multiuse biological raw material with a high economic importance for a number of industrial sectors such as construction, furniture and the packing industry. It is much more variable than that of materials such as concrete or metal (Michael, 2016). Global production of wood is estimated at 3469 million m3 in 2011, of which 1891 million m3 is fuel wood and 1578 million m3 is industrial round wood. Wood is a natural, renewable and valuable construction material. Since being thought of as naturally resistant to wood degrading organisms. Wood has been used as a shelter and has many outdoor applications thought out human history. However, the durability of wood varies depending on its tree species, chemical composition and the environmental condition. Wood biodegradation occurs in different ways such as fungal, bacterial and insect attack. Fungal decay is the most widespread type of wood degradation. The demand for wooden products is continuously increasing day by day. Wood is exposed to both periodic water absorption and desorption process. Understanding water absorption and desorption in wood are of practical importance since they also affect the mechanical properties of the product. In residential building and in industrial application some of the components are often wood (Ostman, 1985). To develop buildings and its components different engineering properties are important. In the present study, the bending stress of ain was found as 5.67 × 107 kN/m2 and compression stress was found as 1.3×107 kN/m2.Keywords
