Is boiler feed water demineralized?
Boiler is used to produce steam for power generation. The water feed to the boiler must not contain any dissolved solids. This type of water is known as demineralized water. Dissolved solids such as hardness and other mineral salts will result in the scaling and deposits in the boiler.
What is the difference between feed water and boiler water?
Cooling water is used in industrial processes to dissipate large amounts of heat. Boiler feed water, on the other hand, is used in the water/steam circuit for electricity generation in power stations. The water has to meet specific requirements for both applications, which is why it is analyzed on a regular basis.
Is boiled water the same as demineralised water?
Demineralised water is water that has been purified in such a way that (most of) its mineral- and salt ions are removed. Distilled water is purified by boiling and re-condensing. In this way salt ions are being removed.
Which water is used as boiler feed water?
The boiler receives the feed water, which consists of varying proportion of recovered condensed water (return water) and fresh water, which has been purified in varying degrees (make up water). The make-up water is usually natural water either in its raw state, or treated by some process before use.
Where is boiler feed water?
Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser.
What is difference between DM water and purified water?
Soft water is also used to feed purified water plant. Purified water is highly pure water then de-mineralized water and produced using DM Water. To prepare the purified water, soft water is passed through Reverse Osmosis membrane and ultraviolet light….Follow Pharmaguideline.

What means boiler feed water?
Feedwater is water that undergoes purification or preheating and is then supplied to boilers for hot water and steam production, or it can remain still. It is typically found in thermal power plants where it is stored and conditioned in tanks, known as boiler feedwater.
