Abstract

이 발명은 보일러의 열교환기에서 연소실에서 발생한 연소열을 효과적으로 이용하고 그 크기를 소형화하도록 하는 보일러용 열교환기에 관한 것으로, 하부몸체에 지그재그로 수로를 요설하여 수로와 직접 접촉하는 접촉면적을 넓히고 열교환기 외부 저면에 흑색이며 전열성이 양호한 세라믹으로 코팅처리를 하여 연소실에서 발생한 연소열을 용이하게 흡수하고 상,하부몸체와 가수켓에 다수개의 배기가스 통공을 뚫어 배기가스에 의한 2차 열교환도 이루어지도록 한 특징이 있으며 종래에 있던 핀을 제거하여 구조가 간단하므로 가공이 용이하고 소형화시킬 수 있으며 수로의 길이가 길어 연소열 및 배기가스열을 효율적으로 흡수할 수 있는 등의 우수한 효과가 있는 발명이다.The present invention relates to a heat exchanger for a boiler that effectively utilizes the combustion heat generated in the combustion chamber in the boiler heat exchanger and reduces its size. It is black on the bottom and coated with good heat transfer ceramic to easily absorb the heat of combustion generated from the combustion chamber, and through the exhaust gas through the upper and lower bodies and the jacket, the secondary heat exchange by exhaust gas is also performed. In addition, since the structure is simple by removing the conventional fin, it is easy to reduce the size of the process, and the length of the channel is long, and the invention has an excellent effect of efficiently absorbing combustion heat and exhaust gas heat.
