Problems solved by technology

Secondly, the proposed energy efficiency index is based on the "relative energy efficiency" based on the baseline energy consumption, rather than "absolute energy efficiency". The selection of the baseline energy consumption is highly subjective and lacks an objective assessment of the actual energy consumption level of the enterprise.

Abstract

The invention relates to a steel flow energy efficiency calculation method. The method comprises the following steps: determining energy input of a steel production process; respectively calculating energy loss of each process and energy loss of each interface based on the first law of thermodynamics and the second law of thermodynamics; calculating energy loss of the steel production process based on the sum of the energy loss of each process and the energy loss of each interface; and calculating the energy efficiency eta of the steel production process based on the energy input of the steel production process and the energy loss amount of the steel production process. The steel flow energy efficiency calculation method provided by the invention makes up a blank in energy efficiency evaluation of current steel flow energy systems.

Description

technical field [0001] The invention belongs to the technical field of iron and steel processes, and in particular relates to a method for calculating the energy efficiency of an iron and steel process. Background technique [0002] The iron and steel industry is a pillar industry for the development of the national economy and plays a pivotal role in the industrial system. The iron and steel industry is also a high-energy-consuming industry. The energy consumption of my country's iron and steel industry accounts for about 20.7% of the total industrial energy consumption and 13.6% of the country's total energy consumption. With the proposal of the "double carbon" goal and the continuous intensification of energy constraints in recent years, promoting energy conservation and consumption reduction in the iron and steel industry is the only way to promote its development. The timeliness and scientificity of energy efficiency assessment is the basic work to promote energy conse...
