EFFECT OF DILATION OF COAL BLEND ON PUSH FORCE AND COKE QUALITY IN STAMP CHARGED COKE MAKING PROCESS

An abstract of no more than 200 words The blending of coals as practiced for stamp charged coke making is determined primarily by technical factors and secondary by economic factors. The most common problem in stamp charged coal blending is whether to adjust an operational blend, a common need is to predict the effect on oven health. In stamp charged coke making, push force is a bottleneck for smooth operation of coke oven battery to produce superior quality of coke. In the present study, the relation between dilation characteristics of the coal blends has been investigated by the Audibert-Arnu Dilatometry test. The behavior of different coal blends has been studied to determine the effects of dilation of coal blend on coke CSR and push force. Coke plant data have been used for assessing the impact of dilation of coal blend on coke CSR and oven health. Results showed that dilation of coals blend is important parameters for controlling the coke quality and push force. The influence of some other important parameter on coke quality was also made in this study.
