Abstract

In this paper, in the ventilation system of coal-fired power boilers can measure in real time the fan stall mechanism is all about. 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 석탄화력 발전소의 보일러에서 통풍계통의 맥동을 실시간으로 측정할 수 있는 장치에 관한 것이다. 500MW급 대용량 보일러 통풍계통의 맥동 감시장치는 팬 이상 발생시 팬을 보호하기 위하여 정지시키는 기능을 한다. 그러나 맥동 감시 장치의 빈번한 고장으로 신뢰성이 저하되고 운전에 영향을 미치므로 이것을 DCS(Distributed Control System) 로직으로 구성하여 신뢰성을 향상시켰다.
