Operation Characteristics of Pilot-Scale Gasification System for Coal Syngas Production

석탄 합성가스 제조를 위한 pilot급 가스화 시스템 운전특성

Gasification has been regarded as a very important technology to decrease environmental pollution and to obtain higher efficiency. The coal gasification process converts carbon containing coal into a syngas, composed primarily of CO and $H_2$. And the coal syngas can be used as a source for power generation or chemical material production. This paper illustrates the opeartion characteristics and results of pilot-scale coal syngas production facilities. The entrained-bed pilot scale coal gasifier was operated normally in the temperature range of $1,300{\sim}1,400^{\circ}C,\;2{\sim}3kg/cm^2$ pressure. And Indonesian KPC coal produced syngas that has a composition of $46{\sim}54%\;CO,\;20{\sim}26%\;H_2,\;and\;5{\sim}8%\;CO_2$.
