Dump tube is a device to reduce the high-temperature and high-pressure steam to specified pressure required by the user. According to the device desuperheating and decompression integrated or not, it can be divided into an integrated dump tube and split type dump tube. It is mainly used for the power plant which operating with high temperature and high pressure steam that need be isolated in some reasons to push the high pressure superheated steam into the downstream equipment.The conversion of different quality steam, such as high, medium and low pressure steam pipe networks, is connected by a desuperheater. When the steam load fluctuates, the dump tube can maintain the steam temperature of each pipe network and stable pressure.
