초록
폐목재의 에너지 전환을 위하여 2톤/일 규모의 고정층 가스화기(0.9m×2.4m)를 제작하여 실험하였다. 고정층 가스화 설비는3∼5 cm의 목재칩을 이용하였으며 하부에는 회전식 스토커가 설치되어있다.목재칩 연료 투입은 다단 나이프밸브 방식으로 되어 있으며 관성력 집진설비, 가스냉각용 열교환기, ID Fan 및 Cooling tower 등으로 구성되어져 있다. 가스화기는 700~1000 ℃ 사이에서 조업하였으며 CO: 25∼40 vol%, H2: 7∼12 vol%, CH4: 2∼4 vol%, CO2: 12∼24 vol% 의 조성을 가지는 합성가스가 생성되었다. 합성가스 발열량은 1100∼1500 kcal/Nm3으로 나타나 공업로의 적용이 가능하였다. 또한 합성가스의 가스 엔진을 통한 전력 생산도 가능하여1∼4 kW의 전력을 생산하였다.
For the conversion of domestic waste-wood into energy, a fixed bed gasifier (0.9 m × 2.4 m) having the capacity of 2 ton/day was designed and constructed. The dual knife valve was used to feed waste-wood of which size was 3∼5 cm and a rotary stoker system was installed in the bottom of gasifier. The pilot gasification system consisted of feeding system, fixed bed gasifier, gravity fine particle collector, heat exchanger for syngas cooling, ID fan, and cooling tower. The operation temperatures of gasifier were 700∼1000℃and the concentrations of syngas were CO: 25∼40 vol%, H2: 7∼12 vol%, CH4: 2∼4 vol%, CO2: 12∼24 vol%. The calorific value of syngas was 1100∼1500 kcal/Nm3 and was enough to be applied in the industrial combustor. Also the gas engine was operated by using syngas from biomass gasifier and produced 1∼4 kW of power.
