KAJI EKSPERIMENTAL PENGARUH TEMPERATUR KARBONISASI, DAN SUPLAI UDARA TERHADAP KARAKTERISTIK PEMBAKARAN BIOBRIKET TONGKOL JAGUNG
ABSTRACT: The world energy
consumption has been increasing
continuously. On the other hand reserve of energy resources, specially
fossil fuel energy resources tend to decrease. To anticipate the scarce of
energy or even crisis of energy, the study to look for the source of
alternative energy require to be done. Energy sources of agriculture residue
biomass, specially corn cob is very attractive to be studied because of its
availability which is abundante ( 7.315.861 ton / year) but not yet been
exploited maximally.
This research investigated the influence of carbonisation temperature,
briquetting pressure and velocity of air on combustion characteristic of corn
cob biomass. In this research,
carbonisation was conducted in three different temperatures, i.e. 2200C,
3000C and 3800 From the experimental result, it can be
concluded that process of carbonisation can improve content of fixed carbon,
heating value and mean of heat released rate of fuel. Increasing carbonisation
temperature will increase heating value, decrease mean of CO emission of
charcoal production, but the mean of
mass losses and heat released rate will decrease. Increasing velocity of
supplay air will increase the mean of mass losses and flue gas temperatur will
go down. From air velocity 0,1 m/s to
0,3 m/s, CO emission goes down and goes
up at 0,4 m/s. C. Supplay of combustion air were varied with four velocities,
i.e. 0,1 m/s, 0,2 m/s, 0,3 m/s and 0,4 m/s.
