Once the water is converted to steam, it is collected in an empty tank called a dome.
Boiler Three Element Controller Philosophy A single element control system is one with just one control input, a two element control system is one with two control inputs, etc. A three-element boiler water level control system is one which typically uses the measured water level, the steam flowrate from the boiler, and the water flowrate into the boiler to regulate the flow of water into the boiler.
In other cases, special forced circulation boilers have been designed, which consist of many rows of tubes without a steam drum. In another type, heat is supplied by steam from a standard type of boiler which heats the water in a direct contact heater. This is referred to as a cascade system.
Boiler (power generation) - Wikipedia. A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
