Palm kernel shell (PKS) is actually the by-product from palm oil industry, before the era for palm kernel shell being used as biomass, the oil palm owner will bury the palm kernel shell underneath the land and let it becomes black color palm kernel compost. This is sort of organic fertilizer but because of the hard shell, it takes much longer time for converting totally to organic fertilizer. It is well known biomass product because of it small in size and high in heat energy or calorific value. Palm kernel is kernel from oil palm fruit. After the oil palm fruit gone through the palm oil process, the kernel will be separated and kernel oil will further be distilled and it also gained it status as a bio fuel resource for biomass product. It also classified as a renewable energy that complies with country energy regulation, such as Japan, Korea and Europe. Palm kernel shell also consider as the replacement for wood chip. Gross Calorie Value : 3.600 Kcal , Moisture : 14-20% ( Maximum 20% due to rain ) , Impurities : < 3% ( Maximum 3%) , Ash Content : < 3% ( Maximum 5%) , Size : 4-20mm. , Sulfur : < 0.1% ( Maximum 1%) .
Palm kernel shell (PKS) is a by-product of the palm oil industry but is fast becoming an important source of feedstock for biomass energy generation. Although always traditionally used by palm oil mills as a source of energy, interest from power generators is growing. Features: High calorific values Low sulphur content Specification: Total moisture: 11 % Ash (ADB): 0.75 % Gross Calorific Value (ADB): Minimum 4000 kcal/kg Sulphur (ADB): Below 0.2% Foreign Materials Content: Below 3%
Screening or drying process provides the best quality in the form of pure shells that are free from other materials. In this process the palm shells will be cleaned from stone, soil, iron and so on. This separation process will have a high calorific value. This is palm shell which has high quality because it is a pure material without being mixed with other ingredients. Screening is carried out specifically on a machine.
