Abstract
IGCC와 PFBC에 적용될 수 있는 다공성 세라믹 필터의 펄스-젯 시스템을 최적화하기 위해서 탈진 성능에 영향을 미치는 인자에 대한 연구를 수행하였다. 동반류가 있는 시스템의 경우 경제적인 운전을 위해서는 노즐관의 크기, 확산기목의 크기 그리고 펄스-젯 압력이 중요한 요인이 되는데, 본 연구에서는 상온상압의 경우 노즐관의 크기가 0.4-0.6 cm, 확산기의 목은 2-3 cm 그리고 펄스-젯 압력이 4-5 atm의 범위가 최적 조건이었다. 또한 실제 현장에서 적용될 수 있는 고온고압과 확산기의 목이 2.5 cm의 조겅에서는 노즐관의 직경이 약 0.4 cm이고 펄스-젯 압력이 50-60 atm인 경우가 최적이었다.
To optimize the pulse-jet cleaning system of porous ceramic filters applied to IGCC and PFBC, the effects of factors on the cleaning performance were invsetigated at a temperature of 298.15K and pressure of 1 atm and 723.15K and 20 atm, respectively. The diameter of nozzle, the size of diffusor throat and pulse-jet pressure were the main factors of pulse-jet system. In case of 298.15K and 1 atm, the effective diffusor throat size was 2 to 3 cm which depended on pulse-jet pressure, the diameter of nozzle 0.4 to 0.6 cm and pulse-jet pressure 4 to 5 atm, respectively. In case of 723.15 K, 20 atm and the diameter of diffusor throat was 2.5 cm, the optimum diameter of nozzle was about 0.4 cm and pulse-jet pressure 50 to 60 atm, respectively.
