Water in Cane Sugar Mills: Its Uses, Care and Treatment

01/01/1982 · The remedy for both excessive sugar and mud in the boiler water is the same, i.e. neutralizing the acidity in the boilers by use of large quantities of NaOH or Na 2C0 3 to maintain the pH between 10 and 11.5 and replacing the boiler water by non-contaminated water from the emergency storage tank; removing the source of contamination as soon as possible by ditching the contaminated

Technical Note: Using Guided Wave Radar for Level in High

There will also be dielectric property changes both in the liquid and steam phases. Steam under high pressure and temperature will slow down the propagation speed of a radar signal which can cause up to a 20% error, if not compensated. Even though the dielectric of water decreases with temperature increase, the level can be

Service systems | Dairy Processing Handbook

Steam boilers. Two main types of boilers are used for the generation of steam: the fire tube boiler (which is the most common type in dairies) and the water tube boiler. The choice is influenced by the required steam pressure and steam power, i.e. the quantity of steam utilized at a given time. Boilers for low pressures and small power outputs

PRACTICAL APPLICATION OF SPECIFIC AND CATION

The basics of conductivity measurements used in steam power plants are reviewed and boilers, in which boiler blowdown does not exist, also tend to increase dependence upon on- since the ionization of water changes only with temperature, not with dilute salt concentration. Similarly, the mobility of salt ions varies with temperature

Water and impurites - WordPress.com

Just as river water leaves impurities behind as it evaporates, boiler water leaves impurities behind in the boiler as it turns to steam. This is explained as follows, starting from a beaker of tap water containing 2 ppm of calcium, the amount of calcium left behind becomes twice as concentrated to 4 ppm.
