Boiler feedwater treatment

The boiler house is the most important part of an industrial power plant. Because they are used 24 hours a day, everyday, treatment of boiler feedwater is key to successful operation. Boiler systems are constructed primarily of carbon steel that is particularly susceptible to corrosion.

It is critical for water used for steam generation to be free of impurities, minerals and suspended particles. A plant that maintains good feedwater achieves the following benefits:

  • Achieve maximum life out of its boilers, steam turbines, condensers, and pumps.
  • Reduce maintenance expenses.
  • Maintain optimal performance

Boiler feedwater treatment involves the following technologies:

  • Clarification
  • Media Filtration
  • Membrane/Ultrafiltration
  • Ion Exchange- softening
  • Ion Exchange – demineralization
  • Reverse Osmosis
  • De-aeration

 

Condensate Polishing

Condensation generated from steam in power plants is collected and reused as boiler feed water. Thus it is imperative for the condensate to be polished or purified so that it cannot cause potential damage to machinery.

Condensate polishing involves ion exchange technology to reduce suspended solids and trace dissolved minerals that cause corrosion and downtime. This process prevents premature chemical failure and corrosive deposits from leading to inefficiencies and possible mechanical damage.

Key condensate polishing technologies include:

  • Ion exchange systems

Cooling tower water treatment systems

Cooling towers with electric generators require a consistent, reliable source of water that is cost-effective and sustainable.  Treatment of cooling water reduces corrosion in the cooling tower and in the blowdown systems. This extends the life of cooling equipment and cleaner water is discharged into the environment.

The choice of cooling tower water treatment technologies depends on factors such as raw feed water quality, desired water quality and flow requirements.
