Gas Applications

Howden has supplied over 140 gas compressors to PWR plants across Europe, North America, China, Japan, South Korea, India and South Africa. Additionally our gas circulators are used within existing AGR and newer HTGR designs for small modular reactors. Our compressors can also be found within nuclear research facilities such as ITER.

Chart's cryogenic expertise is centred on gas treatment used within nuclear systems and storage in gaseous or liquid form.

Gas cooled reactors require circulation of the cooling gas (typically helium or carbon dioxide) for heat transfer - Gas blowers/circulators.

Compression of the circulating inert cover gas for moderators - Diaphragm compressors.

Compression of gaseous waste from the treatment system to tank storage - Diaphragm compressors.

Maintains nitrogen pressure within the system used to remove remaining water from the reactor cooling system - Diaphragm/Screw compressors.

Safe storage of critical gases for use on site - Tanks, vessels and portable liquid cylinders.

Air Applications

Howden has over 50 years of experience supplying over 15,000 fans within various nuclear facilities from electrical power to fuel manufacturing, waste treatment, research and decommissioning sites.

Fresh air, exhaust air, heating, and cooling throughout all areas of the plant. Maintaining a constant negative pressure within controlled areas.

Safe cooling of the vessel and other structural materials during an accident.

The movement of air in and out of the filtration system used to control air quality by capturing radioactive particles.

Removal of unsafe concentrations of gas to maintain reliable atmospheric conditions.

Contributing to efficient, safe and comfortable working environment within nuclear facilities.

Maintaining a constant negative pressure within controlled areas during dismantling or back-up/emergency situations to ensure radioactive materials are safely contained.

Heat Exchange and Cooling Applications

Howden's fans are installed in many nuclear power plants worldwide in association with cooling. Howden and Hudson (both Chart Industries companies) axial fans have long-standing use within utility cooling systems for nuclear energy and Chart is also a supplier of Air Cooled Heat Exchangers (ACHE) and steam heat exchangers.

Safe cooling of the vessel and other structural materials during an accident - Axial/centrifugal/mixed flow fans.

Cooling air for process and utility provide through systems based on cooling towers and air-cooled condensers - Axial cooling fans.

Converting reactor heated water to steam for electrical power or thermal use - Shell & Tube heat exchangers.

Removing excess heat from the power production process - Air Cooled Heat Exchangers.

Compression within the refrigeration cycle of helium coolant used in fusion reactors - Screw compressors.

Energy and Power Applications

Howden has a long heritage of power generation systems throughout industrial applications through our Kühnle, Kopp & Kausch and Peter Brotherhood brands. These turbines provide up to 40MW of power and have installations within nuclear power plants in USA, Belgium and Sweden. Additionally our steam turbines are used across various heavy industries to drive mechanical equipment such as pumps.

Electrical output through steam-based generation.

Efficient use of waste energy for additional electrical or heat output.

Drives for major equipment such as pumps.

Water Applications

AdEdge 和 BlueInGreen 的综合技术为多种水污染物的去除/处理提供了完整的处理解决方案组合。

Removal of undesired contaminates through filtration, distillation, and vaporisation to a level suitable for release or use in other processes.
