Power cycle chemistry monitoring

November 2015 Analytical Instrumentation & Environmental Monitoring

The Mettler Toledo Thornton DCC1000 system offers a new design for conductivity measurement in power cycle chemistry monitoring. This system provides assurance of water purity to maximise power production and minimise corrosion.

High purity water is used in the water/steam cycle in power generation and maintaining its purity is essential to ensure that sensitive equipment such as turbines are not damaged by contaminants. As a leading manufacturer of process analytics instrumentation, Mettler Toledo Thornton has launched the DCC1000 degassed cation conductivity system for use in pure water applications in power plants. The system will help technicians make the best decisions for increasing load as well as for plant operations.

Monitoring corrosive contaminants is very important at all stages of power plant operation – while starting up the plant, monitoring these contaminants can ensure the water quality is adequate for bringing the plant online. In a running plant, monitoring power steam quality can ensure contaminant limits specified in turbine warranties are met.

With accurate and reliable conductivity measurements using UniCond conductivity sensors, the DCC1000 system confirms water purity to maximise power production and minimise corrosion. The DCC1000 system is optimised to perform specific, cation and degassed cation conductivity measurements to monitor the quality of feed water, steam, power steam and power condensate applications. Benefits include faster plant start-ups and a better understanding of plant characteristics and maintenance.

At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
