Natural Circulation Boiler Steam Drum,
Horizontal Boiler Steam Drum,
ASME Standard Boiler Steam Drum
High Pressure Boiler Steam Drum For Industry Use Natural Circulation
Steam drum is a cylindrical pressure vessel used in water-pipe boiler for steam separation and steam purification, forming a water circulation loop and storing pot water. Its main function is to receive water from economizer, separate steam from water and supply water to circulation loop, and transport saturated steam to superheater. There is a certain amount of water in the drum, which has a certain amount of heat and material savings. When the working conditions change, the speed of vapor pressure change can be slowed down. When the water supply and load are not coordinated for a short time, it plays a buffer role. The drum is equipped with internal devices for steam-water separation, steam cleaning, medication in the pot and continuous sewage discharge to ensure steam quality, as shown in the figure.
Steam drum is the most bulky and expensive thick-wall pressure-bearing component in boiler. The drum not only withstands high internal pressure, but also produces thermal stress due to the fluctuation of wall temperature due to the change of operating conditions. Therefore, the working conditions are bad, and effective operation condition supervision is needed.
(a) The main components in a boiler system are the boiler feedwater heaters, deaerator, boiler, feed pump, economizer, boiler, superheater, attemperator, steam system, condenser and the condensate pump.
(b) In addition there are sets of controls to monitor water and steam flow, fuel flow, airflow and chemical treatment additions.
The main functions of drums are:
1. It is the junction hub of three processes of working medium heating, evaporation and superheating to ensure the normal water circulation of boilers.
2. Inside, there are steam-water separator and continuous blowdown device to ensure the quality of boiler steam.
3. Have a certain amount of water, have a certain capacity of heat storage, ease the change speed of vapor pressure;
4. The drum is equipped with pressure gauges, water level gauges, accident discharge water, safety valves and other equipment to ensure the safe operation of the boiler.
