Disclosed is a fly ash deposit preventive apparatus for a power plant. The disclosed fly ash deposit preventive apparatus for a power plant comprises: a support casing fixed to a facility of the power plant and having a cylindrical shape; an air compression filling unit which is installed on the support casing to seal the inside of the support casing, and is filled by the air compressed by being supplied from outside; a low-frequency vibration generation unit which is installed on the air compression filling unit to be able to make a straight motion, accumulating the force for operation by compressed air introduced into the air compression filling unit through an air control valve, and discharging the accumulated force as the compressed air of the air compression filling unit is selectively discharged to generate a resonance low frequency to the support casing while making a straight motion; and a resonance tube which connects a heat exchanger or an exhaust duct of the power plant to the support casing, and resonates the low frequency generated by the low-frequency vibration generation unit. Accordingly, the present invention is able to transfer a low frequency into a combustion system or an exhaust system, thereby effectively removing foreign substances such as dust attached to the inside.

    본 발명은 발전소용 비산재 퇴적물 부착 방지장치를 개시한다. 개시된 발전소용 비산재 퇴적물 부착 방지장치는, 발전소의 시설물에 고정되며, 원통 형상을 가지는 지지 케이싱과, 지지 케이싱의 내부를 밀폐하도록 지지 케이싱에 설치되며, 외부에서 공급되는 공기가 압축되어 충진되는 공기압축 충진부와, 공기압축 충진부에 직선 운동 가능하게 설치되며, 공기조절밸브를 통해 공기압축 충진부로 유입되어 충진되는 압축 공기에 의해 작동을 위한 힘을 축적하고, 공기압축 충진부의 압축공기가 선택적으로 배출됨에 따라 축적된 힘이 방출되어 직선 운동하면서 지지 케이싱으로 공진 저주파를 발생하는 저주파 진동 발생부와, 발전소의 열교환기 또는 배기덕트와 지지 케이싱을 연결하며, 저주파 진동 발생부에서 발생하는 저주파를 공진하는 공진튜브를 구비하는 것을 특징으로 한다. 따라서 본 발명은 연소계통이나 배기계통의 내부로 저주파를 전달하여 그 내부에 부착된 분진 등과 같은 이물질을 효과적으로 제거할 수 있다.
