Abstract

The invention provides an establishment method and application of a comprehensive evaluation model of solid fuel for sintering. The method comprises the following steps that S1, a comprehensive evaluation model of the solid fuel for sintering, in consideration of mixed combustion reaction behaviors of different types of solid fuel under an adiabatic system based on an energy balance principle, mainly establishes three main indexes, namely a theoretical combustion temperature, a harmful gas emission index and a use cost index; S2, based on the three main indexes, the model establishes a fuel evaluation characteristic value K meeting production requirements; and S3, the comprehensive evaluation model calculates a fuel evaluation characteristic value K of a solid fuel batching scheme of a predetermined type and a predetermined ratio, and quantitatively evaluates the advantages and disadvantages of different fuel batching schemes by comparing and analyzing the K values. The model is convenient to calculate, has important guiding significance for selection and optimization of types and proportions of fuels produced by field sintering, and can also be used for evaluation of other types of fuels for sintering for modification of corresponding indexes.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a method for establishing a comprehensive evaluation model of solid fuel for sintering and its application. Background technique [0002] At present, with the development of the iron and steel industry and the continuous improvement of the blast furnace clinker ratio, the supply of coke powder for sintering is in short supply. Many sintering sites use biomass charcoal, semi-coke, blast furnace dust or anthracite to replace or partially replace coke powder as solid fuel for sintering. . However, due to the large difference in the combustion properties of these solid fuels and coke powder, the type and proportion of solid fuel used in the sinter mixture will have a significant impact on the sinter production cost, flue gas emission and sinter quality. [0003] Previously, most researchers used the sintering cup experiment method to directly compare the effects of various solid ...
