Product Description
The concept of drum refers to the pressure drop or rise caused by the water circulation. It can also be understood that the drum is the pressure change formed by the fusion of gas and water. The air and water molecules in the limit pressure will increase the pressure rise of the gas, resulting in the pressure gathering molecules producedafter the high pressure reaches a certain value. In industry,drum tank is an industrial equipment which can withstand the air pressure and water level pressure produced by the drum.
Steam drum is the most important pressure component in natural circulation boilers. It is mainly used in medium pressure and high pressure subcritical boilers in power generation.
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/and saturated-steam into the steam-drum.
working
The separated steam is drawn out from the top section of the drum and distributed for process. Further heating of the saturated steam will make superheated steam normally used to drive a steam turbine. Saturated steam is drawn off the top of the drum and re-enters the furnace in through a superheater. The steam and water mixture enters the steam drum through riser tubes, drum internals consisting of demister separate the water droplets from the steam producing dry steam. The saturated water at the bottom of the steam drum flows down through the down comer pipe, normally unheated, to headers and water drum. Its accessories include a safety valve, water-level indicator and level controller. Feed-water of boiler is also fed to the steam drum through a feed pipe extending inside the drum, along the length of the steam drum.
A steam drum is used without or in the company of a mud-drum/feed water drum which is located at a lower level. A boiler with both steam drum and mud/water drum is called a bi-drum boiler and a boiler with only a steam drum is called a mono-drum boiler. The bi-drum boiler construction is normally intended for low pressure-rating boiler while the mono-drum is mostly designed for higher pressure-rating.
On steam locomotives the steam drum is also called a steam dome.
