应用范围
Process heat in a power plant is provided by steam at different pressures. The required process temperature is regulated via the steam pressure. Depending on the process temperatures there can be pressures up to 160 bar, at temperatures up to 400 °C in the steam drums. Reliable control of water levels and fail safe limit of high and low water in the steam vessels are crucial for the safe operation of the plant.
