side senses the boiler drum pressure, the weight of the water above the low pressure tap and the weight of a column of saturated steam from the high pressure tap to the water level.
The steam drums and, (in a 5-drum boiler) the water drums, are however linked by short horizontal pipes and these form part of the circulation circuit. The tubes themselves are seamless-drawn steel and mostly straight,
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 History· Working· Types of Steam Drums· See also· ReferencesSteam Boiler: September 2011steamofboiler.blogspot.com/2011/09Drum level control is installed on the outside of drum in a steam boiler system. Drum level control is commonly, although not often, installed by using float settings.
