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

Abstract

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 flow in iron and steel procedures, improves the reliability of the steam measurement, solves the problems of measurement shortage and disputes caused by low accuracy and stopped measurement in iron and steel enterprises steam measurement, and achieves energy assessment, energy conservation and consumption reduction.

Description

technical field [0001] The invention relates to a method for authenticating steam production and consumption in different processes of iron and steel enterprises. Background technique [0002] my country's iron and steel enterprises consume a large amount of energy every year, and reducing energy consumption of iron and steel is of great significance to the healthy development of the national economy. Recycling and utilization of waste heat and waste energy to generate steam and reuse is one of the effective means of saving energy and reducing consumption in iron and steel enterprises. Each process point is connected with a steam pipe network to realize the comprehensive utilization of steam. In order to reduce energy costs, enterprises are required to measure the instant flow and cumulative flow of steam between the production process connected to the steam pipe network and the user process, and to conduct economic assessment of process energy consumption, so as to strengt...
