ABSTRACT

Rice husk is a kind ofbiomass which is very much common in the rural re^on of Vietnam. We can see piles

of rice husk at the back of the rice mill Normaly rice husk uses as fuel to cook in families, brick furnaces and grain

dryers.

Rice hud: is directly burned in the traditional stoves. The direct burning method has disadvantage.

This paper present a new rice husk burned method. Rice husk converts into carbon monoxide and hydrogen

by reacting the raw material with a controlled amount of oxygen. This new called gasification method

It is based on nutrition demand of each meal for members in the family, the author calculates and designs a

newgasfier stove which uses rice husks as fuel The parameter of the stove such as:

- The diameter of combustion: 250mm

- Heigft of reaction combustion: 600 mm

- The volume of reaction volume: 0,03m3

- The toted of height of the stove: 900mm

- Capacity of fan: 65W ^^

- Capacity of combustion: 6,4kW.
