Experimental method for predicting quality of cokes at different height positions in coke oven

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 ...
