Straw is the by-product of rice harvesting. It contains 14% ash, which is the highest ash content in straw.
It can be used alone to produce gas, but the gas quality is poor. It is generally not recommended to use it alone, and the mixed use ratio should not be too large. This material is best used as a component of gasification fuel.
Rice husk is the product of rice processed by rice. It is in granular form and is a good gas-making fuel, but the amount of air intake must be controlled.
