Trisodium citrate has the chemical formula of Na 3 C 6 H 5 O 7.It is sometimes referred to simply as "sodium citrate", though sodium citrate can refer to any of the three sodium salts of citric acid.It possesses a saline, mildly tart flavor.It is mildly basic and can be used along with citric acid to make biologically compatible buffers.
What you commonly know as sugar is sucrose, a polar compound made of carbon, hydrogen and oxygen. Sucrose in itself does not have a pH level, because pH is a measure of concentration and not the property of a particular chemical. The same applies to other sugars, such as lactose, fructose and glucose. At room temperature, sugar is highly water

Steam Boiler: Function, Classification & Applications. It is a fire tube, horizontal, internally fired, and natural circulation boiler, stationary and low-pressure boiler. Since it is a low-pressure boiler steam production will be less. Due to the lower steam production, the efficiency of the boiler is also low compared to the water tube boiler.
Here are some principles to help establish an effective blowdown program: 1. In drum-type boilers, the concentration of the water should be controlled by blowdown from the steam drum. Continuous blowdown is preferred. 2. Also in drum boilers, blowing from the mud drum or bottom headers removes suspended solids from the boiler.
Water tube boilers were developed for a variety of reasons, including the need for higher steam pressures, higher steam generation rate, superheated steam. these types of boilers have quicker response to load changes. We briefly discuss about Water tube boiler parts and functions. In the water tube boiler, the water and steam flow inside the
The solubility of aluminum, as a function of pH, in a hydroxide equilibrium environment, is illustrated in Figure 8. On the alkaline.side of the curve, the main species present is mono- valent AL(OH)4 , while under acidic conditions the main species is the trivalent form Al .
Star Alka Boiler Treatment provides the alkaline conditions for Star One Shot BWT to function correctly. Without the correct precipitation and subsequent blow down of hard water salts, scale deposits would form. This would result in restriction in water flow, ineffective heat transfer and local corrosion.

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.
