What is the shrinking and swelling effect in boilers

* Swelling: If suddenly steam demand increases in the turbine (due to increased load), then steam generation will increase and consequently steam output from the boiler drum will be higher. Due to this a sudden drop in boiler steam pressure will

Effects of Shrink or Swell Phenomena - Chemical plant

Dec 22, 2006 · The addition of a sixth boiler is driven by steam demands, but it would also provide another layer of boiler protection. The tricky part of drum feed water level control is due to the 'shrink and swell' phenomena as result of drum pressure drop with high steam demands. The water in the boiler drum and tubes have liquid flashing to vapor, so

Plant Engineering | Maintaining boiler safety

Low-water trips protect boiler pressure parts by shutting down the fuel combustion process, eliminating high temperatures in the furnace when the natural circulation cooling process is interrupted. Control of the boiler drum level is sophisticated, and even the best-tuned control systems cannot always prevent a low-water condition.

Boiler Drum level control | Instrumentation and Control

Mar 19, 2018 · Basic Function of Drum level control: A boiler is used to heat water to steam. To accomplish this a series of tubes are placed in the boiler to confine the water and provide a large heat transfer surface for interfacing with the hot gases of combustion. The water in these tubes is turned to steam. The steam is used in energy conversion purpose.

Water-tube boiler - Wikipedia

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

control and maintain the drum level. If the drum level drops too low, the boiler can suffer thermal stress damage. If the level gets too high, steam leaving the drum may carry some water particles along, which can cause damage to turbines or other steam users. Finally, fluctuations in drum level cause interactions with the boiler combustion
