A method for improving the transverse runout curve of the side combustion chamber

By adding a gas intake pipe and adjusting the damper opening on the coke oven gas pipeline, the coke oven gas was used to heat part of the vertical flue, which improved the horizontal curve of the side combustion chamber, solved the problems of inconsistent coke maturity and small flue ignition, and improved the safety of the coke oven and the quality of coke.

AI Technical Summary

Technical Problem

Uneven horizontal curves in the side combustion chamber lead to inconsistent coke maturity, resulting in small flue ignition and affecting the safety, stability, and quality of the coke oven.

Method used

A gas intake pipe is added to the coke oven gas pipeline and connected to the blast furnace gas system through the first exchange valve. The opening degree of the gas side and air side dampers is adjusted, and the coke oven gas is used to heat part of the vertical flue. The temperature is adjusted by adjusting the coke oven gas nozzles, thereby improving the shape of the horizontal curve.

Benefits of technology

It improved the safety and stability of the coke oven and the uniform maturity of the coke, solved the problem of small flue ignition, and improved the quality of the coke.

Abstract

The application provides a new method for improving side combustion chamber horizontal row curve, relates to the technical field of coke oven thermal regulation, and is mainly applied to the current large coke oven. With the prolongation of service time, the existence of factors such as the absence of fire clay between the masonry structure of the coke oven, the damage of the masonry, acid and alkali corrosion and the like, the internal leakage phenomenon of the coke oven occurs. Through the optimization and improvement of the equipment, the vertical flue corresponding to the side waste gas on-off valve control of the side combustion chamber is heated by coke oven gas instead of blast furnace gas. The side combustion chamber horizontal row curve in actual operation can be optimized from the'steamed bun type' to the 'oblique line type', and the uniform and stable maturation of the coke in the horizontal direction is ensured.
