일반적으로, 보일러는 발전소 또는 산업용으로 필요한 증기를 생성하는 장치로서, 그 구성요소를 살펴보면 증기를 발생시키는 본체(노, 과열기, 재열기, 절탄기) 및 순환계통과, 연료의 공급 및 연소를 통해 보일러 내에 열원을 공급하는 연소장치, 연소에 필요한 공기의 공급 및 연소와 가스를 방출시키는 통풍장치, 기타 보일러를 빠져 나가는 연소가스로부터 열량을 회수하는 공기 예열기, 보일러 본체 내에 축적되는 회분을 제거하기 위한 제매기, 보일러 본체를 보호하기 위한 안전 밸브 등 부대설비로 이루어진다.In general, a boiler is a device for generating steam necessary for a power plant or industrial use, and its components are described in terms of the main body (furnace, superheater, reheater, and coal mill) and circulation system that generate steam, and the supply and combustion of fuel. Combustion apparatus for supplying heat source to the inside, supplying air for combustion and ventilating system for releasing combustion and gas, air preheater for recovering heat from the combustion gas leaving the boiler, agent for removing ash accumulated in the boiler body It consists of auxiliary equipment such as a mag, a safety valve to protect the boiler body.

한편, 상기 보일러의 노 외벽을 이루는 루프 패널(Roof Panel)에는 라운드 튜브가 설치되고, 상기 라운드 튜브의 양 측면에는 코일 번들(Coil Bundle)의 통과 공간 확보를 위한 쏘우 컷 핀(Saw Cut Fin)이 구비된다.Meanwhile, a round tube is installed on a roof panel forming a furnace outer wall of the boiler, and saw cut fins are provided on both sides of the round tube to secure a passage space of a coil bundle. It is provided.
