Pengaruh Equilibrium Kandungan Air Batubara Halus Terhadap Nilai Kalor Bakar Batubara Halus (Fine Coal)
Abstract: The increasing of
requirement of domestic cement for a number of years will affect directly to
usage of coal as especial fuel for cement production. So that Important to know
the usage condition of coal yielding coal with superordinate calorivic value,
with better economic value, and smaller negative impact to environment, where
with slimmer usage amount of coal better yield coal with higher calorivic value
because more and more amount of used coal also will improve the waste that able
to influence environment. Have been researched water equilibrium of fine coal
with aim to lessen the amount of fine coal usage for cement production process,
because from data result of research got calorivic value which mounting of fine
coal after done equilibrium of water content in fine coal. Fine coal sample
before and after obstetrical equilibrium of its water is determined change of
that calorivic value (Cal/g) use Bomb Calorimeter PARR 1261, content of water
(%) use Moisture Analyzer, content of sulphur (%), and its dusty content.
Result of which is got that after water equilibrium happened minimizing the
mass of fine coal’s sample, after done the determination of water content
happened minimizing of water content that is equal to 3.14% or happened
minimizing that equal to 17% from water content before equilibrium. While for
the calorivic value increase until 189 Cal/g or happened increase equal to 3%
from calorivic value of sample before equilibrium, for sulphur and dusty
content happened increase successively equal to 7% and 5% from content of
sample before equilibrium.
