Analisa Spesifikasi Fluff, Pellet, Dan Bricket Dari Pelepah Kelapa Sawit Sebagai Biomassa Co-Firing Untuk Pembangkit Listrik

---

The government has officially issued SNI 8966:2021 which contains
standard parameters for biomass to be used as co-firing fuel. One of the biggest
challenges of implementing co-firing is the unstable biomass supply. Therefore, by
utilizing the abundant availability of palm frond waste, it is hoped that this problem
can be overcome. This study was conducted to review whether oil palm fronds in
the form of fluff, pellets, and brickets can be used as co-firing fuel. In addition, this
study also aims to see whether there are differences in the potential of hard and soft
palm fronds as solid jump fuel for power plants, as well as calculate the analysis of
the potential slagging and fouling of all types of biomass studied.
The study began with the process of shredding oil palm fronds and drying
samples using an oven until the moisture content was lost ≤10%. Next, the midrib
was reduced in size using a wood chipper and sifted with a 20 mesh sieve. After
that, the sample was dried again in the oven at 60oC for 3 hours so that palm frond
fluff was formed. Meanwhile, for hard frond wood pellet products, it also began
with the formation of fluff, then fluff was mixed with 22% tapioca adhesive with a
weight ratio of 20% of the biomass. Next, the mixture was molded with pellet molds
before drying in the oven at 60oC for 3 hours. Finally, for hard frond wood bricket
products, it began with pyrolyzing the frond (T = 550oC and t = 5 minutes). Next,
the charcoal was mashed to 20 mesh size before being mixed with 22% tapioca
adhesive with a weight ratio of 30% of the biomass. After that, the mixture was
molded with a bricket mold before drying in the oven at 105oC for 1 hour. Finally,
laboratory tests were carried out on all samples that had been made by conducting
proximate analysis tests, total sulfur, GCV, NCV, and chemical analysis on ash.
From the results of the analysis carried out, it is known that hard frond
wood bricket type fuel provides the best results and is classified as first-class fuel
with an NCV value of 7095 cal/g. Furthermore, both hard frond fluff and soft frond
fluff types belong to the same fuel class and produce the same sulfur content
analysis value (0.06%) based on SNI 8966:2021. Therefore, the difference in using
hard or soft fronds as co-firing fuel does not have much effect. Furthermore, based
on the analysis of potential slagging and fouling, all types of oil palm frond samples
studied provided quite good analysis results because they had a low to medium risk
level.
Key words: SNI 8966:2021, co-firing, fluff, slagging and fouling.
