Palm Kernel Shells for Steam Boilers In Palm Oil Mills

Palm oil industry generates large quantity of biomass waste, that is, palm kernel shells or PKS. This type of biomass waste has great potential in using as biomass fuel for boiler.

Palm kernel shells as biomass source

Palm kernel shells (or PKS) are the shell fractions left after the nut has been removed after crushing in the Palm Oil mill. Kernel shells are a fibrous material and can be easily handled in bulk directly from the product line to the end use. And they contain residues of Palm Oil, which accounts for its slightly higher heating value than average, in addition, the moisture content in kernel shells is low compared to other biomass residues with different sources suggesting values between 11% and 13%. Therefore, palm kernel shells are primarily used as a boiler fuel supplementing the fibre which is used as primary fuel in industrial boiler.

While in recent years, bulks of palm kernel shells are processed and sold as biomass fuel for boilers, especially for steam boilers in palm oil mills. We know palm oil mills need steam boiler to run turbines for electricity production. The PSK are by-product in the mills and it is cost-effective for them to use the biomass steam boiler burning palm kernel shells.

Palm kernel shells steam boiler in palm oil mills

In recent years, the demand for palm kernel shells has increased for palm oil mills self-sufficient in in terms of energy by making use of kernel shells and mesocarp fibers in cogeneration. Our typical biomass boiler that can burn palm kernel shells is chain grate boiler. Membrane water-cooling wall, single-drum or bi-drum, horizontal arrangement, and it has high automatic degree to ensure the boiler running safely. Users can choose different boiler size based on their own requirement.
