Steam drum - Wikipedia
A steam drum is a standard feature of a water-tube boiler. It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture. The difference in densities between hot and cold water helps in the accumulation of the "hotter"-water ...
Boiler Steam drum internals and function
The size of the steam drum is determined by the volume required for a clean separation between steam and water to produce a dry saturated steam, it also provides an adequate amount of steam storage. The steam drum is also called the upper drum. Steam drum internals for typical type of boiler are shown. The internals include separation devices ...
Boiler Steam Drum Explained - saVRee
Watertube boiler steam drums are located at the top of the boiler, above all other boiler parts. The steam drum is characterized by its long, cylindrical shape, and is usually made from thick steel plate to withstand the high pressures and temperatures at which it operates. A steam drum may be up to two meters in diameter and 30 meters in length.

9-Functions of Boiler steam drum - Power plant and calculations
2023年10月9日 · A steam drum is a crucial component in many types of boilers, particularly in water-tube boilers. Its primary function is to separate steam and water to ensure the proper operation and safety of the boiler. Here are the main functions of a steam drum in a boiler: 1-Steam-Water Separation:
Steam drums for power generation - ametek-measurement.com
2024年11月7日 · The steam drum is the primary interface between water and steam. In a coalfired plant, boiler feedwater passes through the economizer and into the drum where the steam separates from the feedwater and is drawn off to the superheater. In combined-cycle operations, a Heat Recovery Steam Generator (HRSG) serves the same purpose as a boiler.
Steam Drums - mechanical steam-water separators
Steam drums generally serve to: - provide limited buffer water storage (for a number of minutes) in order to accommodate abrupt changes in boiler load. However, primary function of steam drums is to effectively separate steam from water. This can be attained by providing a large steam-water surface for natural gravity-driven separation.
