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 (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

High Pressure Boilers: Meaning, Types, Characteristics

This boiler uses distilled water for its operation for generating high pressure steam. This steam is recirculated without any wastage in the circuit. In this case high pressure steam generated from pure water is used for generating low pressure steam from impure water or normal water and is used for power generation.

the importance of boiler water and steam chemistry

The Importance of Boiler Water and Steam Chemistry

Steam Purity Purity or chemistry requirements for steam can be as simple as a specified maximum moisture content, or can include maximum concentrations for a variety of chemical species. Often, for low pressure building or process heater steam, only a maximum moisture content is specified. This may be as high as 0.5% or as low as 0.1%.
