The task of burning rice husk for cooking purposes is not so simple with the constraints of this context. Heat generation from rice husk cannot be achieved efficiently with a simple ‘direct’ combustion.Proper gasification, with the aid of forced air, would be the best technical way, but this work has focused on an intermediate solution, where rice husk in part burns ‘directly’ and in part is gasified.
No available or reliable electricity prevents the possibility to use fans or blowers, while some draft is fundamental for operation.Hence, natural draft is provided by the pressure gradient given by the height of the chimney if the pot is sealed in its proper position.
