Abstract

In this paper, The fan stall guard system of boiler airing system of the class of 500MW capacity to protect fan. But because confidence is loosed and operation is influenced by frequent fault of fan stall guard system, confidence is improved by substituting DCS Logic for it.

본 논문에서는 500MW급 대용량 보일러 통풍계통의 Fan Stall 감시장치는 Fan 이상 발생시 Fan을 보호하기 위하여 정지시키는 기능을 한다. 그러나 Fan Stall 감시장치의 빈번한 고장으로 신뢰성이 저하되고 운전에 영향을 미치므로 이것을 DCS(Distributed Control System) Logic으로 구성하여 신뢰성을 향상시켰다.
