Expansion tank for atmospheric open gas boiler

摘要

This research is the expansion tank of the open gas boiler,In particular, as one of the functions of expansion tank, the exhaust gas is more flexible, so in order to improve the reliability of gas boiler,In the expansion tank (40), a grid (43) (43) (43) is formed to have a large number of outflow holes (43A). In order to maintain a certain interval (L), a double setting is set, thus hindering the flow rate of circulating heating water, so as to better remove air.
