직경 7.5 ㎝ 실험실용 유동층 석탄 가스화 반응기를 수치 해석하기 위하여 기체의 경우 bubble assemblage model, 고체의 경우 population balance model을 기초로 하여 지수함수형태의 단위 기초반응속도식을 적용 해석하였다. 반응기 온도(750-1000℃), 공기 유량(1.5-5.0 ㎏/hr-air/㎏/hr-char), 수증기 유량(0.5-2.5 ㎏/hr-steam/㎏/hr-char) 변화 조건에서 생성가스는 H₂(10-30%), CO(5-20%), CO₂(6-12%), CH₄(2-4%)의 몰 농도 조성 변화를 나타내었다.

The numerical analysis for the 7.5 ㎝ I. D. atmospheric lab. scale fluidized bed coal gasifier was conducted with the bubble assemblage model for gas, the population balance model for solid, and the basic coal gasification kinetic equation in the form of power law. The mole percent of H₂ in the product gas was 10-30%, that of CO was 5-20%, that of CO₂ was 6-12%, and that of CH₄ was 2-4% with variation of the simulation condition such as temperature(750-1000℃), air flow rate(1.5-5.0 ㎏/hr-air/㎏/hr-char), and steam flow rate(0.5-2.5 ㎏/hr-steam/㎏/hr-char).
