Power Plant Applications

Humidity 2 Optimization offers an absolute humidity sensor that is accurate and tough enough to be installed from the economizer outlet to the stack in power plant applications.

The absolute humidity sensor is designed to be used in the following applications at combined cycle power plants and coal/biomass fired boilers:

Combined Cycle Plant

• Verhoff equation input – Acid Dew Point / Stack Temperature Optimization
• Tube leak detection
• Environmental reporting
• Power augmentation feedback

Depending on plant size, from 300 MW to 1000 MW, the fuel savings can range from approximately $170,000 to $560,000 per year utilizing stack temperature optimization. You can enter your plant-specific information in the downloadable calculator spreadsheet. See the following post for an indepth explanation, CCPP Stack Temperature Optimization | H2O Optimization

Coal/Biomass Fired Boilers

• Tube leak detection
• Soot blower feedback
• Heat rate calculations
• Air heater in-leakage
• Dry scrubber control – adiabatic saturation temperature
• Environmental reporting
• Wet scrubber stack protection
• Pulverizer control
