Coke thermal performance analyzing method and thermal difference type coke thermal performance reactor

Abstract

The invention discloses a thermal difference type coke thermal performance reactor. The thermal difference type coke thermal performance reactor comprises a reactor barrel, an end cover, a separation sample hanging basket and a suspension piece, wherein the separation sample hanging basket is internally provided with separation sample plates; the separation sample plates are used for separating the separation sample hanging basket into a plurality of separation sample regions; the middle part of the separation sample hanging basket is provided with a long hole; the suspension piece comprises temperature-control couple arranging pipes, a general connection pipe and a plurality of temperature measuring couple arranging pipes; the temperature-control couple arranging pipes and the temperature measuring couple arranging pipes are communicated with the general connection pipe; the general connection pipe is fixedly connected with the end cover; the temperature-control couple arranging pipes are placed in the long hole; the plurality of temperature measuring couple arranging pipes are respectively placed into the corresponding separation sample regions; the bottom of the separation sample hanging basket is provided with a sample disc; and the sample disc is provided with a plurality of air vents. The thermal difference type coke thermal performance reactor disclosed by the invention can obtain thermal difference curves of different small coke sphere samples under the same heating condition, and can judge good and bad conditions of two parts of coke hole wall substrate materials and the degree of the coke porosity through comparing a change tendency of the two thermal difference curves.

Description

technical field [0001] The invention relates to the technical field of coking, in particular to a method for analyzing thermal properties of coke and a thermal differential coke thermal property reactor. Background technique [0002] Coke is a carbon-based fuel with a porous structure, which acts as a skeleton and a reducing agent in a blast furnace. Due to its skeletal effect, the blast furnace operation has higher requirements on the cold strength and heat load strength of coke. At present, the thermal strength characterization of coke is mainly carried out through the coke post-reaction strength and coke reactivity in the national standard GB / T4000-2008. The result of this method is to characterize the quality of the coke through the strength of the drum after the coke reaction. However, coke is mainly corroded by carbon dioxide in the blast furnace and its strength decreases. At present, there is no suitable method to measure the effect of coke pore structure and pore ...

AI Technical Summary

Problems solved by technology

In the blast furnace, coke is mainly corroded by carbon dioxide and its strength decreases.

At present, there is no suitable method to measure the effect of coke pore structure and pore wall matrix material properties on the reaction rate of coke, and the strength of coke after reaction cannot be obtained.
