Distribution structure of heating gas outlets in vertical flame path partition walls

Abstract

The invention relates to a distribution structure of heating gas outlets in vertical flame path partition walls; a plurality of heating gas outlets are formed in the vertical flame path partition walls in the height direction, and the heating gas outlets in different vertical flame path partition walls are the same in number and are in one-to-one correspondence; the heights of the corresponding heating gas outlets on different vertical flame path partition walls are different. According to the invention, the heating gas outlets on the vertical flame path partition walls are distributed in a fluctuating state in the transverse direction of a coke oven, so that the corresponding flame combustion points are highly staggered, the local high-temperature points of the oven wall of a carbonization chamber can be avoided while the height-direction heating uniformity of the coke oven is improved, and the service life of the oven wall of the coke oven is prolonged.

Description

technical field [0001] The invention relates to the technical field of coke ovens, in particular to a distribution structure of heating gas outlets on a flue partition wall which is beneficial to prolonging the service life of the coke oven wall. Background technique [0002] The coke oven is a complex industrial furnace that operates continuously at high temperature for a long time. The carbonization chamber made of silica brick is an important part of the coke oven. The service life and working efficiency of the coke oven are closely related to the stability of the furnace wall of the carbonization chamber. Unreasonable design and non-compliant production operations will destroy the stability of the furnace wall, resulting in a reduction in the working efficiency and service life of the coke oven, which will bring huge economic losses to the enterprise. [0003] At present, large-scale coke ovens often use two-stage or three-stage heating methods, that is, gas and air are ...

AI Technical Summary

Problems solved by technology

However, in the existing multi-stage heating coke oven, along the transverse direction of the coke oven, the corresponding gas outlets on all flue partition walls are on the same horizontal line (such as figure 1 shown), this design may lead to excessive local temperature of the coke oven wall, damage the masonry of the coke oven wall, thereby reducing the service life of the coke oven wall
