What is the function of boiler drum?
21 Jan 2022
The boiler drum is connected with downcomer and water wall to form a natural circulation loop. At the same time, the boiler drum receives the feed water from the economizer and delivers saturated steam to the superheater. Therefore, the boiler drum is the connecting hub of the three processes of heating, evaporation and overheating in the boiler.
There is a certain amount of water in the boiler drum, it has a certain energy storage capacity. When the working condition of the boiler changes, it can slow down the speed of steam pressure change, which is beneficial to the operation adjustment, thus improving the safety of the boiler operation.
The boiler drum is equipped with various equipment to ensure the steam quality. For example, the steam-water separator in the steam drum can separate the salty water droplets in the steam; cleaning device in steam drum can remove dissolved salt in steam.
