Problems solved by technology
In the process of energy efficiency analysis and calculation, even if the drawings and documents are complete, a complex and repeated calculation is required for a parameter change, which consumes a large amount of labor. An energy efficiency analysis report generally requires multiple data adjustments. It takes several days or even more than ten days to use conventional "manual" calculations, and the probability of error in the results will increase due to the large amount of data and the large number of table lookup parameters
The current technologies related to furnace energy efficiency evaluation and analysis are generally not universal and versatile

The embodiment of the present invention provides a method and equipment for evaluating and analyzing the energy efficiency of a metallurgical gas-fired furnace. The method includes: constructing a basic database of metallurgical gas furnaces, a database of physical properties of commonly used materials, and an energy efficiency evaluation and optimization standard library; importing test data required for heat balance calculations, and excluding unqualified data according to the rules of the test data; The calculated data is retrieved from the physical property database of commonly used substances, calculated according to the calculation rules of heat balance income items and expenditure items, and the calculation results are obtained. If the judgment basis value is within the preset threshold range, the calculation results are correct; according to the metallurgical gas furnace Furnace type specifications in the kiln basic database, the average index and advanced index in the energy efficiency evaluation and optimization standard library are screened, and energy efficiency optimization measures are formulated. The method and equipment for evaluating and analyzing the energy efficiency of metallurgical gas furnaces and kilns provided by the embodiments of the present invention can quickly diagnose and evaluate the energy efficiency levels of various gas furnaces and kilns.
Description
technical field [0001] The embodiments of the present invention relate to the field of metallurgy technology, and in particular to a method and equipment for evaluating and analyzing the energy efficiency of metallurgical gas-fired furnaces. Background technique [0002] In the production process of iron and steel enterprises, the energy consumption of gas furnaces represented by gas combustion accounts for a large proportion, which is one of the key points of energy saving and consumption reduction. Furnace energy-saving equipment improvement and implementation of technical means must rely on furnace energy efficiency analysis (heat balance test). In the process of energy efficiency analysis and calculation, even if the drawings and documents are complete, a complex and repeated calculation is required for a parameter change, which consumes a large amount of labor. An energy efficiency analysis report generally requires multiple data adjustments. It takes several days or e...
