Embodiment 1

[0025] Such as figure 1 As shown, the embodiment of the present application provides an experimental method for predicting the quality of coke at different heights in the coke oven, including:

[0026] Step 110: Obtain the height H of the coke oven to be tested from the coal charging port to the bottom of the carbonization chamber, the conventional coal charging height h, and the average width d of the carbonization chamber;

[0027] Step 120: Determine the height h and width d of the experimental coal charging container according to the size of the coke oven to be tested, wherein the width of the experimental coal charging container is the same as the average width of the coking chamber of the coke oven to be tested; determine the The distance h'=H-h between the actual coal charging port of the coke oven produced by the experimental coal charging container and the coal line after leveling coal;

[0028] Further, in the method, the length of the coal charging container is gre...

Embodiment 2

[0047] In order to introduce the embodiment of the present invention more clearly, a 7.63-meter coke oven is taken as an example below.

[0048] Step 110: The height of the 7.63m coke oven from the coal charging port to the bottom of the carbonization chamber is about 9m, the conventional coal charging height is 7 meters, and the average width of the carbonization chamber is 590mm;

[0049] Step 120: Design the experimental coal charging container with a height of 9 meters and a width of 590mm, and the distance h'=2 meters between the actual coal charging port and the coal line after leveling coal;

[0050] Step 130: Build a belt conveyor on the platform 2 meters above the experimental coal charging container, and freely load the production coal into the container at a certain speed; stop coal loading when the production coal overflows from the upper part of the container, and use a scraper to scrape the coal above the container. Gently scrape off the coal sample along the edg...

Abstract

The invention discloses an experimental method for predicting quality of cokes at different height positions in a coke oven. The method includes steps: acquiring a height H from a coal loading port toa coking chamber of a to-be-tested coke oven, a conventional coal loading height h and an average width d of the coking chamber; determining a height h and a width d of an experimental coal container; determining a distance h' between an actual coal loading port and a coal line after coal leveling in an experimental coal container production coke oven; acquiring a total loading bulk density rho in the experimental coal container; determining a height h1 between a researched position and the bottom to obtain bulk density rho 1 at the h1; performing a coking experiment, accurately controlling bulk density of each section and the total loading bulk density rho to be identical, and establishing a corresponding relation between experimental coke and produced coke; after bulk density of each section is controlled to be identical to the bulk density rho 1 at the h1, acquiring a strength index of the experimental coke, and finally acquiring an index of coke produced at the height h1 between the researched position and the bottom according to the corresponding relation between experimental coke and produced coke.

Description

technical field [0001] The invention relates to the technical field of coking, in particular to an experimental method for predicting coke quality at different heights in a coke oven. Background technique [0002] The top-loading coke oven is to control the coking coal to drop continuously from the coal charging port on the top of the furnace by gravity, and then the flat coal rod enters the carbonization chamber and extends forward along the top of the carbonization chamber to the coke side, and finally achieves a full, tight and flat state. Purpose. However, due to the way of gravity falling coal loading, the coking coal at the bottom is continuously squeezed and impacted by the upper part, resulting in the phenomenon that the bulk density in the briquette gradually decreases from the bottom to the furnace top. [0003] In the process of realizing the technical solution of the invention in the embodiment of the present application, the inventor of the present application ...
