Process Water Analytics for Power Stations

Green and renewable energy sources like solar and wind power are making inroads in today’s energy market. Nevertheless, thermal power stations are still the backbone of generating electricity and process steam in many countries and industries.

Steam, Cooling, and Condensate: Water for Every Process Step

The energy source for these power stations can be coal, oil, gas, nuclear power, or green energy like biomass and geothermal energy. Thermal power stations work with a thermodynamic cycle in which pure boiler feed water is converted into the steam that drives the turbines for electricity generation. The steam can also directly be used to heat buildings or in industrial processes. Used steam is cooled down and forms liquid condensate. The condensate is transported back to the boiler in order to trigger the thermodynamic cycle again. Alongside the boiler feed water cycle as a core process, a thermal power station requires feed water treatment systems (reverse osmosis, ion exchanger), a cooling water system, a flue gas scrubbing system, and of course, a wastewater monitoring system.

Related Applications

Flue Gas Desulfurization
pH value measurement in the pre-scrubber, the neutralization phase, and the lime scrubber as part of the flue gas desulfurization process in power plants.
Cooling Tower Monitoring
In a wide range of industrial sectors, cooling towers are used to dissipate process heat from cooling circuits. Mineral deposits and corrosion reduce their efficiency and lead to premature wear on plant parts.
Water Treatment Systems
Measurement of pH value, dissolved oxygen, and redox potential in various applications during the water treatment process of power plant wastewater.
Ion Exchanger Systems
Measurement of pH values, dissolved oxygen, and conductivity in boiler feed water, steam, and condensate in combined gas turbines in power plants.
Reverse Osmosis Systems
Reverse osmosis systems are used for water treatment in a wide range of industrial applications. The main application is industrial saltwater desalination.
Monitoring Steam Generators
Since steam generators fulfill application-critical functions and the cost of their downtime or replacement is extremely high, damage caused by wear should be prevented by monitoring water quality.
Combined Cycle Power Plants
Measurement of pH values, dissolved oxygen, and conductivity in boiler feed water, steam, and condensate in combined gas turbines in power plants.
Cooling Water Systems
Measurement of pH value, redox potential, and conductivity in cooling water, which has to be continuously treated with acid and biocides.
Boiler Feed Water Circuits
Measurement of pH values, dissolved oxygen, and conductivity as key parameters in the boiler feed water circuit.
