Characteristics of boiler feedwater - Lenntech

Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica

pitting can result with possible rupture of boiler condensate piping or boiler tubes. 3.3.4 Rusty water in the boiler gage glass is a sure sign of acid corrosion in the boiler feedwater/condesate system or in the boiler itself. 3.3.5 Make-up water is the major source of carbon dioxide. The first priority is to minimize the amount of make-up water.

On-Line Water Chemistry Measurements for Power Plants

pH is the measurement of the free acidity or alkalinity of a solution; in this case, the solution is water. The measurement of pH is critical to prevent corrosion processes from occurring. The second leading cause of boiler failure can be attributed to corrosion. However, pH measurement in high purity water can be extremely difficult.

Fly ash - Wikipedia

Fly ash, flue ash, coal ash, or pulverised fuel ash (in the UK) – plurale tantum: coal combustion residuals (CCRs) – is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called

Boiler feedwater - Wikipedia

History of feedwater treatment. During the early development of boilers, water treatment was not so much of an issue, as temperatures and pressures were so low that high amounts of scale and rust would not form to such a significant extent, especially if the boiler was "blown down". It was general practice to install zinc plates and/or alkaline chemicals to reduce corrosion within the boiler.

Boiler Water Treatment | Sensors for Process Control

BOILER WATER TREATMENT. A boiler is a closed vessel where water under pressure is transformed into steam by the application of heat. This process is useful for a variety of industries, from industrial and manufacturing environments to food and beverage processing. In the boiler furnace, the chemical energy in the fuel is converted into heat.

In high-purity systems, raw water in-leakage (e.g., condenser leakage) lowers boiler water pH when magnesium hydroxide precipitates, resulting in corrosion, formation of atomic hydrogen, and initiation of hydrogen attack. Coordinated phosphate/pH control can be used to minimize the decrease in boiler water pH that results from condenser leakage.
