In order to improve the boiler efficiency, the header boiler is gradually developed into a tube boiler to increase the heat transfer area. The boiler water flows from the drum to the lower box through the downcomer, and it distributed to each tube bundle by the box. The water in these tube bundles continuously absorbs heat energy, and then flows back to the drum after being collected into the upper header. The upper and lower header are called headers. The header is an important part of the boiler, which is divided into upper header and lower header.
