Bellino is a benchmark in the technological field of steam desuperheating, a fundamental process used to lower the temperature of superheated steam to a target value, usually close to the saturation temperature. This process is crucial in multiple applications, as the use of high-temperature steam is advantageous only in specific situations, such as turbine expansion, while it becomes complex to manage in terms of energy and construction in contexts like district heating or temperature-controlled industrial processes. The desuperheating process typically takes place through the injection of a specific amount of water at a predetermined temperature into the steam flow: the sudden evaporation of the injected water rapidly lowers the average temperature of the mixture without altering its pressure. The control loop can be set up using either feedback (thermocouple placed at an appropriate distance from the injection point) or feedforward (enthalpy balance).
