Characteristics of rice husk and RHA
* Rice husk is difficult to ignite and it does not burn easily with open flame unless air is blown through the husk. It is
highly resistant to moisture penetration and fungal decomposition. Husk, therefore, makes a good insulation material.
* Rice husk has high silica (SiO2) contents which means that it decomposes slowly when brought back to the field. It also makest a poor foder.
* Handling of rice husk is difficult because it is bulky and dusty. It has angle of repose is about 40-45° which means that it's flow ability, e.g. in feed hoppers is very poor.
* Rice husk has low bulk density of only 70-110 kg/m3, 145 kg/m3 when vibrated or 180kg/m3 in form of brickets or pellets. It thus requires large volumes for storage and transport, which makes transport over long distances un-economical.
* When burned the ash content is 17-26%, a lot higher than fuels (wood 0.2-2%, coal 12.2%). This means when used for energy eneration large amounts of ash need to be handled.
* Rice husk has a high average calorific value of an 3410 kcal/kg and therefore is a good, renewable energy source.
* Because of the high silica contents rice husk is very abrasive and wears conveying elements very quickly.
* Rice husk is not an easy fuel. One concern in rice husk firing is the behavior of the ash, i.e., its slagging and fouling
tendency caused by a low melting point of the rice husk ash.
