A typical boiler has a lower drum/vessel known as the mud drum and an upper drum/vessel called the steam drum. These two drums are connected by a series of tubes where water is circulated. The tubes closest to the heat source are called raisers, and they circulate water from the bottom mud drum to the top steam drum where steam is generated.

Steam drum separator section typical of modern drum type natural circulation boilers. Avallone, et al. (1987). The mass flow rate of drops less than 10 microns in diameter is quite small in typical steam generation installations so the mass fraction of liquid flowing out of the separator section for installation of this type is typically of the order of 0.1 percent.

2018/5/30 · Boiler Steam drum internals and function. In the water tube boiler the upper drum (Boiler steam drum) provides for separation of steam from water. It also provides liquid holdup capacity (typically 10 to 60 seconds) to allow for a dynamic response to load changes without losing liquid in the downcomer and riser tubes.
Read MoreIn this evaporation process requires heat transfer that be obtained from combustion process in the furnace steam boiler. Evaporation occurs in the water wall tubes of steam boiler. Water from steam drum is flown through downcomer into lower header, and the proceed to water wall tubes either in the left side, right side, front side and rear side steam boiler.

The steam drum is one of the important parts of the boiler which acts as the reservoir for the steam generated and for water required for the boiler. Mainly all the boiler mountings are mounted on the steam drum and it should possess sufficient strength to withstand the high temperature and pressure of the steam generated.

Steam Drum Steam drum is most important part of boiler. Boiler - baffle-assisted separation: simple screens and baffle arrangements are used for improving the steam-water separation process. Baffles provide among others changes in the direction, more even distribution of the steam-water mixture as well as additional flow resistance.

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.

Steam-Water Separation. Steam-water separation is one of critical process in the steam boiler system especially in steam drum. Steam is usually installed in steam generators and high pressure boilers. The principal purpose is to allow for separation of saturated steam out of the mixture of steam-water and then goes to superheater for next process.
