Stoves for rice husk and other fine residues

Rice husks and other fine residues have historically been regarded as worthless wastes and disposed of by being burnt on site or flushed away into rivers. By converting them into a resource they become an asset rather than a liability. The major sources like rice-husk, sawdust, millet husk and peanut shells can often be burnt.  Such residues are converted into briquettes. In some circumstances this is a good solution and a lot of research has been done on how to make and burn briquettes. However, briquetting is an extra process and adds cost to the fuel, and is not always appropriate. So, the raw material can directly be used in the stove. The types of stoves burning these residues are rice husk stoves, sawdust stoves, cooking stoves and heating stoves. In addition, more advanced cooking stoves systems are also used to burn residues such as belonio rice husk gas stove and rice husk gasifier bakery oven. Therefore, carefully designed technologies enable the people living in poverty to use such fuels cleanly and cheaply.
