Dynamic Shrink/Swell and Boiler Level Control – Control Guru

As high pressure boilers ramp up to operating temperature and pressure, the volume of a given amount of saturated water in the drum can expand by as much as 30%. This natural expansion of the water volume during start-up is not dynamic shrink/swell as discussed later in this …

Power Plant Efficiency – Simulator Laboratory

Excluding hydroelectric power plants, most power generating plants employ a type of boiler and steam turbine. A schematic diagram of a simple steam power plant is shown below: High-pressure steam leaves the boiler and enters the turbine. The steam expands in the turbine and does work which enables the turbine to drive the electric generator.

Power Plant Efficiency – Simulator Laboratory

Steam with a temperature equal to the boiling point at that pressure is known as dry saturated steam. However, to produce dry steam in an industrial boiler designed to produce saturated steam is rarely possible, and the steam will usually contain droplets of water.

An introduction to steam generation and distribution

Trevithick was the first to successfully use high-pressure steam (then known as "strong" steam). Until ca. 1800, the weakness of existing boilers coupled with the influence of James Watt had generally restricted steam boilers to very low pressures or "weak" steam.

The National Board of Boiler and Pressure Vessel Inspectors - Boiler Efficiency and Steam Quality: The Challenge of Creating Quality Steam …

When a steam valve opens, two problems occur in the boiler. First, steam pressure drops rapidly. The drop in steam pressure itself causes additional entrainment as explained in Case II above. Second, the interface between water and steam rises.
