본문내용
As global warming becomes more serious, eco-friendly technology is drawing attention. One of them is an economizer machine that recover energy from waste heat and uses it again. Such economizers are also installed in boilers that are common around the house, so we have sought to increase the efficiency of economizers of boilers in this project. To determine the conditions of the highly efficient economizer, we tested it by changing various elements. First, it was tested by changing three materials: aluminum, copper, and stainless steel (STS304). The heat transfer (Q) is calculated as 888.33W, 782W, and 721.91W, respectively, and copper with the highest heat transfer was the most efficient material. Then, it was tested by changing the diameter of the pipe. It was tested with aluminum pipes of 11 mm, 22mm and 33 mm, showing heat transfer of 45.85 W, 782 W and 168.9 W, respectively. It was also tested as pipe with 6 bending & 70mm distance between pipes by changing number of bending and the distance between the pipes, and it showed 464.32 W of heat transfer.참고 자료
