If load changes are rapid and of large magnitude, the pressure in the boiler can drop considerably, initiating extremely turbulent conditions as the contents of the boiler flash to steam. To make matters worse, the reduction in pressure also means that the specific volume of the steam is increased, and the foam bubbles are proportionally larger.

Steam generator (boiler) - Wikipedia

2020-12-11 · A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil. Circulation is once-through and pumped under pressure, as a forced-circulation boiler.

WHY STEAM? - American Boiler Manufacturers Association

2019-12-17 · Steam will expand when converting from water, by as much as 1700 times its water volume. This is the basis for many applications of mechanical work, as in the early steam engines, where a small amount of water was pumped into the boiler, and a very large volume of steam was produced to operate the train. This property is still used today for
