Saving of Coke Oven Gas by Reduction of Smoke Pushing of Recovery Type Coke Plant

Abstract

For stable oven operation and prolongation of the coke oven life, it is important to remove excess carbon formation on the coke oven wall. It is considered that the carbon formation rate is influenced by the gas components generated during carbonation, the gas velocity and oven wall temperature are not uniformly maintained, as a result of smoke pushing. The smoke pushing is not favourable for the good health of the coke oven battery. In this paper, the smoke pushing can be rectified by proper maintenance of the gas path. Energy consumption and economic growth are interwoven, and rising energy levels always represent rising energy consumption. Coke is a reducing agent and a load-handling tool in blast furnaces. By this rectification, the coke oven gas flow was reduced from 17600Nm3/hrs to 17300Nm3/hrs without any extra manpower cost. The experimental set-up implementation of this modern proposal in a coke plant will make coke more extra energy efficient with no other extra costs.
