Detailed explanation-1: -Thermal efficiencies of the rice husk furnace and the furnace system are approximately 59 % and 58 % (at height of ash 60 an) respectively. Carbon conversion efficiency is 90 % (at height of ash 60 an).

Detailed explanation-2: -The boiler’s efficiency found the same as using of coal (68%) with the rice husk calorific value 15, 217. 20 kJ/kg that means rice husk is cheaper fuel than coal [2, 30] .

Detailed explanation-3: -The density and thermal conductivity of the produced composite was in the range of 378–488 kg/m3 and 0.08-0.14 W/m.K, respectively. The least thermal conductivity i.e. 0.08 W/m.K was observed for the rice husk composite with a density of 378 kg/m3.

Detailed explanation-4: -Rice hulls (or rice husks) are the hard protecting coverings of grains of rice. In addition to protecting rice during the growing season, rice hulls can be put to use as building material, fertilizer, insulation material, or fuel. Rice hulls are part of the chaff of the rice.
