Method for authenticating steam output and consumption in iron and steel enterprises

The invention relates to a method for authenticating different procedures of steam output and consumption in iron and steel enterprises. The method establishes steam flow authentication models for three different procedures: establishing a relationship model between the steam flow and the boiler production variable quantity for a stable steam production source, establishing a relationship model between factors influencing steam output of each device and the steam flow for a procedure of recovering a waste heat steam source, and establishing a relationship model of influencing the steam output and the steam flow in each link for a procedure (user) of consuming the steam. The method formulates a specific implementation process for establishing the steam flow authentication models, establishes a model base, and applies the method combining with searching, mending and updating in the steam flow authentication models. The method provides a real-time authentication method for steam instantaneous flow and cumulative
