Fast, efficient power plant cycling greatly impacts power generation efficiency and revenue. With the growing spread of renewable energy sources, power plants need to be able to reduce production when non-traditional energy sources are available, and quickly cycle on when demand requires it. This trend toward power plant cycling takes a toll on plant equipment, as expansion and contraction of equipment loosens contaminants that can damage turbines and other expensive equipment.
This white paper explores how faster power plant cycling can cause water cycle contamination that effects the lifetime of critical equipment. It examines the role of analytics in supporting a fast power plant cycling program, and how the technology in a degassed cation conductivity panel can help mitigate this risk during power plant start-up.
The white paper, "Stream Sample CO2 Removal for Fast and Reliable Conductivity Measurement" focuses on how a series of different measurements, technologies and calculations on your conductivity panel can work together to provide the rapid,continuous and accurate analysis of conductivity that is needed to ensure that your plant start-up can proceed with minimum risk to your equipment.
A degassed cation conductivity panel, such as the DCC1000e, provides the required measurements for faster power plant cycling. The DCC1000e uses advanced conductivity technology to monitor specific conductivity, cation conductivity and degassed cation conductivity to confirm water purity.
Specific conductivity allows the system to monitor ammonia/amine concentration. Cation conductivity gives an initial indication of the contamination from salts and acids. Degassed cation conductivity gives a clear measurement of key corrosion-causing contaminants, without CO2 interference. These three measurements are displayed on the system's M800 transmitter along with temperature, calculated pH, calculated CO2 and up to one more measurement to support your decision making for start-up and load increase.
Together, this data provides a quick and clear view into your water cycle contamination to allow fast power plant cycling while reducing the contamination impact on your expensive and critical plant equipment.
