PENGARUH KONSENTRASI PEREKAT TEPUNG TAPIOKA DAN TANAH LIAT TERHADAP MUTU BRIKET BATU BARA
Abstract: Making coal
briquettes require tapioca glue and clay. The purpose of this research is
studying the effect of concentration tapioca glue and clay to characteristic
coal briquette. Research carried out by treatment with a concentration of
starch, clay and coal flour respectively as follows; a) 2%, 18%, 80%, b) 4%,
14%, 82%, c) 6%, 10%, 84% and d) 8%, 6%, 86%. The results are showed that the
density of coal briquettes are not affected by the concentration of glue
material, but it is influenced by the pressure of the tool at the time of
manufacture. The lower the content of clay in the briquettes, the stronger the
briquettes were produced and the lower the number of briquettes were broken
when dropped at a height of 2 m. The higher the clay content of the briquettes,
so the timefor the initial combustion, the temperature of the plate surface
reached 180 °C and the duration of briquette became ashes are longer. The rate
of combustion of coal briquettes are made lower than the rate of briquettes combustion
from briquettes non carbonization and carbonization
