Knowing the water concentration at the HRSG outlet in combined cycle power plants can benefit the plant in 3 areas. The areas are corrosion protection during outages, tube leak detection and improved feed water temperature control. Many plants during outages need to eliminate water condensation so the tubes within the HRSG are not exposed to corrosion. Some plants insert balloons to eliminate humid, ambient air entering the HRSG during outages. Another option is to monitor the dew point i... Read More

H2O has adapted our absolute humidity sensor to provide steam quality measurements. Our standard sensor utilizes dipole moment technology which measures the density of a process gas. It is a fixed volume, direct measurement of steam / process humidity. The raw unit of the sensor is g/m3. Non-condensable gases will be determined with our standard system. The density of the saturated steam is fixed at any given temperature and the difference between our measurement and the steam table densi... Read More
The capacity of a spray dryer is the amount of water evaporated within the dryer. The evaporation is directly correlated with the temperature drop across the dryer. The greater the difference between the inlet temperature and the outlet temperature, the more water is evaporated. In order to optimize the capacity, the inlet temperature of the dryer should be as high as possible (within the constraints of the product being dried) and held constant. This also improves the energy efficiency of th... Read More
