The Importance of Boiler Water and Steam Chemistry

Carryover of impurities from boiler water to steam is also inherent to boiler operation. Though separation devices in drum boilers remove most water droplets carried by steam, some residual droplets containing small amounts of dissolved solids always carry through with the steam. Also, at higher pressures, there is some vaporous carryover.

Feeding Water Treatment for Boilers - İTİMAT KAZAN

In the steam boiler or steam generator, as a result of the boiling of the water, the heat transfer occurs on the surfaces, forming a lime layer in the form of crystal (scale, boiler stone). This formed lime layer makes heat transfer difficult and causes energy loss. 1 mm lime formation in boiler flame smoke pipes increases fuel consumption by 6%.

EC: Lesson 11. Scale and sludge formation in boilers

(2) Lowering of boiler safety : Due to scale formation, over-heating of boiler is to be done in order to maintain a constant supply of steam. The over-heating of the boiler tube makes the boiler material softer and weaker and this causes distortion of boiler tube and makes the boiler unsafe to bear the pressure of the steam, especially in high-pressure boilers.

Steam Boiler | What is Steam Boiler | Application and

What is Steam Boiler. A steam boiler 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 steam boiler and worked at low to medium pressure (1–300 psi or 6.895–2,068.427 kPa) but, at pressures above this, it is more usual to speak of a steam generator.
