Through its Bran+Luebbe brand, SPX offers a range of highly effective PowerMon continuous and fully automatic on-line analysers.
Bran+Luebbe has delivered high performance water monitoring analysers for more than 60 years. Their robust form make them ideal for power generation facilities, where they can be used for rapid, accurate monitoring of many diverse parameters to help protect valuable plant machinery.
Silica in boiler feed water can create deposits which impact steam velocity and pressure and in turn negatively affect the capacity and efficiency of the turbine. Deposits on the turbine from steam containing silica can increase rotor thrust and unbalance the turbine rotor. Once deposited, removal of the silica adds significant maintenance costs and interruption to production. The PowerMon Silikometer continuously monitors the silica levels in the boiler feed water and offers excellent performance with a very low concentration detection limit, down to 0.15ppb.
PowerMon series analysers obtain high accuracy and stable results through the use of a high-resolution dual-beam photometer. Sample results for silica concentration, for example, are obtained in as little as ten minutes and, as the analysers have full network capability, any rise in concentration levels can be immediately notified. All PowerMon units offer a reliable solution and, with each device providing up to six measurement points, comprehensive sampling can be achieved with a low initial investment cost.
The PowerMon range meets the needs of approximately 200 different water applications with more than 15,000 analyses possible. They can measure diverse parameters including oxygen, pH, Redox and conductivity with the connection of various sensors. Within the range are units such as the PowerMon S which can replace several single-parameter analysers and can monitor both phosphate and silica concentration levels. The PowerMon Titrometer can determine parameters such as m/p-value, hardness and boron in cooling water.
PowerMon analysers require very low maintenance. Long life bearings, a high quality central motor drive which runs at constant speed, self-diagnostics, automatic calibration and low reagent usage all ensure reduced running costs and increase the periods between maintenance compared with previous models of Bran+Luebbe analysers. Alongside network capability, which enables remote monitoring and easy integration into wider plant control systems, the analysers also have an easily operated local touch screen interface.
Overall SPX PowerMon analysers help to improve plant efficiency. Their low maintenance reduces ongoing costs while their speed and accuracy ensure best protection for plant machinery, helping to avoid the need for premature repair work and unplanned maintenance. Furthermore, their multiple stream and measurement capability ensures a comprehensive and economic solution for water parameter monitoring.
