Water treatment for steam boilers

Relevant technical regulations specify the water composition for supply and additional water in steam boilers. For this reason it is necessary to understand the DESCALER water treatment as additional, even if there are units placed to steam boilers, where without using any water treatment the steam boilers operate to full satisfaction of their operators. Our company also offers units for chemical water treatment. We will be glad to help you select them.

Example of water treatment for medium-pressure

boilers of 25 MW installed capacity

Since water treatment for high capacity steam boilers requires individual approach this manual cannot present a general scheme. It rather gives an example of water treatment for medium-pressure BK 8 boilers of the total installed capacity of over 25 MW. In case of the solution for water treatment for steam boilers of similar capacity it is recommended to consult the suitable method of water treatment by DESCALER units. The system shown in Figure 11 makes use of the original water treatment system, particularly, a reactor that functions as a sedimentation element, sand filters, decarbonised water tank and supply water tank. The feeder of polyphosphates remained as the only elements from the original system of chemical treatment in order to reduce the apparent alkalinity of supply water.
