Custom Dissolved Oxygen monitoring at
Drax

After extensive proving trials, Swan Analytical Dissolved Oxygen meters from Camlab have been supplied to each of the six huge generators at Drax Power Station

Close monitoring of dissolved oxygen in the de-ionised water used to cool the generators is necessary to protect against corrosion of the cooling systems, in this power station that supplies 7% of the UK electricity demand The specially engineered version of the Swan Oxysafe Dissolved Oxygen meter has been developed between Drax Power Station and Swan Systems Engineering (based in Uster, Switzerland) to solve the Drax monitoring requirements

The custom-built unit incorporates a redesigned flow cell with an in-line pressure regulator to maintain constant pressure in the system and prevent bubble formation.

Conventional Dissolved Oxygen meters are unable to handle the Dissolved Oxygen range required at Drax, which extends from trace (ppb) levels, to saturated (ppm) concentrations, partly because of the potential for forming bubbles in the measuring cell.

Reliability at high and low concentrations is an essential requirement for the monitoring technology.

David Miller, Camlab Head of Business for the environment and water markets said, "Our ability to offer customised solutions, backed up by trial instruments, means that we can offer this market a unique service.

The new system will also have applications in CHP (Combined Heat and Power) plants, the Water Utilities and for process water analysis.

We anticipate developments for other on-line analyses".
