본 발명은 보일러의 매진 청소장치에 관한 것이며, 상세하게는 중ㆍ소용량 보일러의 전열면에 부착된 매진을 고압의 물을 자동으로 분사하여 청소하는 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for cleaning dust out of a boiler, and more particularly, to an apparatus for cleaning by spraying high pressure water automatically on dust attached to a heat transfer surface of a medium and small capacity boiler.

주지하는 바와 같이 보일러의 연료로 사용하는 화석연료 특히 액체연료는 그 연료에 포함된 황분과 회분이 연소하면서 황산염, 바나듐, 유황분 등의 연소생성물 이 그을음(煤) 및 먼지(粉塵)(이하 "매진"이라 함) 상태로 전열면에 부착하며, 상기와 같이 전열면에 매진이 퇴적(부착)되면 전열면의 부식을 촉진함과 동시에 열전달을 방해함으로써 열효율이 낮아지기 때문에 상기 매진을 수시로 제거(청소)하여야 한다.As is well known, fossil fuels, especially liquid fuels, used as fuels in boilers, are burned by combustion products such as sulphate, vanadium, and sulfur as the sulfur and ash contained in the fuel burn out. Attached to the heat transfer surface in the state of "," as described above, if sold out (attachment) to the heat transfer surface as described above promotes the corrosion of the heat transfer surface and at the same time prevents heat transfer, the thermal efficiency is lowered (cleaning) shall.

상기한 전열면의 매진제거는 대용량의 보일러에는 슈트 블로워장치를 내장설치하여서, 그 보일러에서 발생한 증기 또는 압축공기를 전열면에 슬라이딩하면서 분사하여 매진을 청소하고 있고, 중ㆍ소용량의 보일러는 보일러 동체의 전열면 상부에 물분사용 구멍을 형성하여 상기 구멍을 통하여 전열면에 고압의 물을 수동으로 분사함으로써 전열면에 퇴적한 매진을 청소하고 있다.In order to remove the sold-out of the heat-transfer surface, a chute blower is installed in a large-capacity boiler, and the steam or compressed air generated from the boiler is sprayed while sliding to the heat-transfer surface to clean the dust. A water spray hole is formed in the upper portion of the heat transfer surface, and high pressure water is manually sprayed on the heat transfer surface through the hole to clean the dust deposited on the heat transfer surface.

그러나 상기한 대용량 보일러는 투자비도 막대하고 증기 또는 압축공기도 쉽게 얻을 수 있으며, 슈트 블로워장치를 추가 설치하는데 경제적 부담이 거의 없음으로 전열면의 매진청소를 간편하고 신속하게 자동으로 할 수 있는 반면에 중ㆍ소용량의 보일러 예컨대 목욕탕용 간접가열 보일러 등은 온수보일러 임으로 증기를 얻을 수 없고 압축공기를 얻기 위하여서는 별도의 콤프레셔를 설비하여야 할 뿐만 아니라 전열면에 별도의 슈트 블로워장치를 부설하려면 부피가 커짐으로 지하실 등에 설치가 불가능하고, 또한 추가비용이 막대함으로써 실현 가능성이 없게 되는 것이다.However, the large-capacity boiler has a huge investment cost, easy to obtain steam or compressed air, and there is little economic burden to install additional chute blower, so that the cleaning of the heat transfer surface can be easily and quickly performed automatically. Small and medium-sized boilers, such as indirect heating boilers for bathrooms, are hot water boilers and cannot obtain steam. In order to obtain compressed air, a separate compressor must be installed. It is impossible to install in a basement, and the additional cost is huge, so that it is not feasible.

한편 상기한 중ㆍ소용량 보일러의 전열면에 고압의 물을 수동으로 분사하여 매진을 청소하는 것은 전열면 상부에 물분사용 구멍만을 부설함으로 비용이 증가하 지 않지만 고압의 물을 수동으로 전열면에 일정시간 분사하여야 함으로 그 청소작업이 불편하고 작업자가 매진에 노출됨으로써 청소작업을 기피하고 있는 실정이고, 상기와 같이 전열면의 매진청소를 기피하면 보일러의 열효율 저하에 의한 연료소비율 증대에 의하여 비용이 증가되는 문제점이 발생하는 것이다.On the other hand, cleaning the sold out by manually spraying high pressure water on the heating surface of the medium and small capacity boiler does not increase the cost by laying only the water injection hole on the heating surface, but the high pressure water is fixed on the heating surface manually. The cleaning operation is inconvenient because it has to be sprayed for a time, and the worker is avoiding the cleaning work by being exposed to the sold out, and if the evacuation of the cleaning of the heat transfer surface is avoided as described above, the cost is increased by increasing the fuel consumption rate due to the decrease in the thermal efficiency of the boiler Problem occurs.

본 발명은 상기한 실정을 감안하여, 중ㆍ소용량 보일러에 간단한 구성으로 간편하게 부설하여 전열면을 자동으로 청소할 수 있도록 한 보일러의 매진 청소장치를 제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a boiler dust cleaning device, which can be easily installed in a medium and small capacity boiler in a simple configuration so as to automatically clean the heat transfer surface.
