Many countries and regions have begun to vigorously develop the use of clean energy, among which biomass energy has been vigorously promoted. In Indonesia, Thailand, Malaysia and other countries, palm plantations are growing and palm oil plants are numerous. These countries have great potential to utilize biomass from palm oil by-products as an alternative fuel source.
Moisture content in kernel shells is low compared to other biomass residues with different sources suggesting values between 11% and 13%. Palm kernel shells contain residues of Palm Oil, which accounts for its slightly higher heating value than average lignocellulosic biomass. From the industry, it is a good quality biomass fuel with uniform size distribution, easy handling, easy crushing, and limited biological activity due to low moisture content.
Fiber waste and palm shells can be used for biomass boiler fuel as a steam source for boiling and processing, as well as a steam generator used for turbine power generation.
Characteristics of palm shells as biomass fuels:
1. High hydrogen and oxygen content, volatile matter up to 70%, which is conducive to rapid ignition and combustion;
2. The sulfur content in the fuel is less than 0.05%. It is not necessary to set up a flue gas desulfurization device during combustion, which reduces the cost and is beneficial to the protection of the environment;
3. Low ash content,
4. The palm shell is dense and resistant to burning, and the calorific value is 10% to 15% higher than that of wood chips.
