To control the alkalinity of boiler water which is directly related to pH control.
Too alkaline will cause stainless steel to brittle while too low alkalinity will cause corrossion.
The concentration of phosphate injected into boiler feed water as a descaler typically ranges from 3 to 15 ppm (parts per million) depending on the specific water conditions and boiler requirements. It is important to carefully monitor and control the phosphate dosage to prevent potential issues like corrosion or scaling in the boiler system. Regular testing and adjustment may be necessary to maintain optimal performance.
A phosphate factory produces phosphate-based products such as fertilizers, animal feed supplements, and industrial chemicals. These products are commonly used in agriculture to improve soil fertility and crop yields.
The steam used in a fossil fuel power station is condensed back into water after it has passed through the turbines. This water can then be reused in the boiler to produce more steam for generating electricity.
Phosphate is a mineral that plays a critical role in plant growth, as it is a component of DNA, RNA, and ATP. It is used in fertilizers to promote healthy plant growth and crop yield. In addition, phosphate is also used in various industrial applications, such as in the production of detergents, animal feed, and food additives.
I have the allergy that is like an auto-immune disorder to milk. I am trying to figure out where the various calcium additives that are found in so many foods comes from.

Boiler feed pumps are an important part of any boiler operation. They control the amount of water fed to the boiler and the manner in which it is fed.
Boiler feed is the fresh or treated water to replenish the water loss though evaporation or leak
A digester feed pump forces water to a boiler. It works by transferring cool water to the boiler to be heated.
If oil is mixed with boiler feed water, it can cause scaling and fouling in the boiler system, leading to reduced efficiency and potentially damaging the boiler components. It is important to prevent oil contamination of boiler feed water through proper filtration and maintenance of equipment to ensure the smooth operation of the boiler system.
The pH value in boiler feed water is typically maintained between 8.5 and 9.5. This range helps to prevent corrosion and scaling in the boiler system. Regular monitoring and adjustment of pH levels are important to ensure the proper functioning and longevity of the boiler.
Function - It adds the pressure to the feed water before it entyers into boiler feed pump suction Advantage - Ensures high margin NPSH A for boiler feed pump spinning at high rpm (5250Rpm) Drive for booster - Normally @1450 rpm Type of impeller- Mostly preferred Double suction
by check valve, one and a half times the pressure of feed water
In boiler feed water line the NRV is normally installed between Pump and stop valve if the line is short and an another NRV is installed at boiler entrance and after stop valve if the line is long or pump is 10 to 15 m away from the boiler.

The boiler feed pump pumps hot feedwater into the boiler. The boiler pressure is to high for water to flow into it by gravity, so a pump is required.
