Mechanism and Prevention of Scale Formation in Boilers
Nucleate boiling heat transfer coefficients may be strongly reduced by scale formation, even for conditions where the bulk foulant concentration is well below the saturation concentration. Due to the mechanism of micro-layer evaporation, the local concentration at the heat transfer surface can be considerably increased, causing the formation of scale and changes in bubble frequency and bubble d...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Assessment of scale formation and corrosion of drinking water supplies in Ilam city (Iran)
Background: Scaling and corrosion are the two most important indexes in water quality evaluation. Pollutants are released in water due to corrosion of pipelines. The aim of this study is to assess the scale formation and corrosion of drinking water supplies in Ilam city (Iran). Methods: This research is a descriptive and cross-sectional study which is based on the 20 drinking water sources in ...
متن کاملTheory of Scale Formation and Prevention Scale Formation and Prevention
Most commercial water contains alkaline earth metal cations such as magnesium, calcium and barium, and anions such as carbonate, bicarbonate, sulfate, silicate, oxalate, phosphate, etc. Different combinations of these anions and cations will give rise to potentially scalant systems, such as calcium carbonate, calcium silicate, calcium sulfate, calcium oxalate, barium sulfate, magnesium sulfate,...
متن کاملBasic Water Treatment of Steam Boilers
In order to fully understand what a given boiler needs for treatment, a basic study of its supply water must be done first. Three types of impurities exist in all supplies and can cause a wide range of problems in boilers and kilns. These impurities are suspended solids, dissolved solids, and dissolved gasses. Water picks up the impurities from the ground it contacts and the air through which i...
