Boiler Water System

Protecting Boiler Efficiency, Reliability, and Sustainability

Flexible treatment programs and boiler services for steam generators & heating systems

Steam is required in nearly all sectors of the industry for different purposes. Steam is used as process steam, or as heating steam supplied to industrial clients and households. In power industry steam is produced to drive turbines for the generation of electricity. In order to ensure high efficiency of steam boilers an optimal boiler water treatment is essential. System disturbances caused by boiler scale, corrosion, local overheating or carryover into the steam reduce the operational safety and may cause substantial economic losses. Kurita therefore provides innovative technologies for boiler water treatment and boiler service to prevent scale and corrosion in the entire boiler system, including the feedwater tank, boiler, steam and condensate systems.

We offer a complete treatment program for a wide range of applications:

  • Steam boilers (low, medium, and high-pressure)
  • Closed water systems
  • Industrial and district heating systems

What kind of boiler services and boiler water treatment products does Kurita provide?

DReeM Polymer® (Dispersion Removal Effects Management Polymer) is Kurita’s advanced boiler water treatment technology that simultaneously prevents new scale formation and removes existing silica and hardness scale during normal boiler operation. Unlike conventional treatments that often require offline chemical cleaning, DReeM Polymer enables continuous operation while restoring heat transfer efficiency and reducing fuel consumption

Cetamine® is an innovative and comprehensive technology for boiler water treatment. It is based on film-forming amines that form a hydrophobic layer on metal surfaces all over the system. Cetamine® builds a continuous barrier between water and metal, thus preventing corrosion without affecting the heat transfer. Cetamine® stands for state-of-the-art water treatment. This new technology provides an easy way to control the whole system – with just one product.

S.sensing® BN-H II is Kurita’s online hardness monitoring system designed to provide continuous, real-time detection of hardness leakage in boiler feedwater and condensate systems.
 
By continuously monitoring water quality, S.sensing® BN-H II helps improve boiler reliability, protect heat transfer surfaces, reduce maintenance costs, and support efficient boiler operation. The system can also be integrated with antiscalant dosing programs such as DReeM Polymer® to optimize scale prevention and maintain stable boiler performance.

Even small quantities of dissolved oxygen may cause corrosion in the feedwater lines, the boiler or the steam and condensate systems. A complete removal by mechanical deaeration is not possible. Kurita offers a variety of volatile and non-volatile oxygen scavengers to remove the remaining dissolved oxygen. Specific products for the application in food industry are available, too.

The formation of scaling in the boiler and especially on the heating tubes reduces the efficiency of hot water and steam boilers and presents a serious safety risk. Even thin layers of mineral scales can considerably reduce the heat transfer of the heating tubes. This usually leads to considerably higher energy consumption for the steam production or in an insufficient quantity of steam generated for the downstream equipment and users. Thicker layers of mineral scales can lead to local overheating of boiler tubes. If no countermeasures are taken tube deformation or even bursting might occur.

To prevent these critical problems, Kurita offers phosphate- and polymer-based scale inhibitors. Potential scale-forming ions in the water are bound, dispersed and then removed from the boiler by blowdown. This prevents scale formation in the boiler and on the heating tubes.

Corrosion in the downstream boiler equipment is mainly caused by condensed carbon dioxide. CO2 in its liquid phase forms carbonic acid, which – by dissociation – reduces the pH value of the condensate. The result: corrosion.

Kurita offers a complete range of neutralizing amines for application in low, medium and high pressure boilers to prevent corrosion in the steam and condensate lines.
