Abstract:

This paper analyzes the influence of blending coal grain size to the production of coke oven battery after the coking chamber is increased.The influence of quantity and quality of crushed coal to the production of battery shall be considered for the determination of its grain size.The grain size shall be controlled to ～70% under normal condition.When the moisture content of coal in monsoon is higher than 13%,grain size can be suitably increased to 70%～75%.
