焦化生产过程配入弱粘结性煤以降低成本的探讨

Discussion on Cost Reduction by Blending Weak Cohesive Coal in Coking Process

通过研究焦化厂生产使用的弱粘结性煤的岩相组成和化学性质以及粘结指数和胶质层厚度等指标,再用小焦炉进行配用研究,在保证焦炭质量的前提下,科学合理地配入弱粘结性煤,经在工业生产中应用,降低了生产成本,实现利润最大化。

The petrographic composition and chemical properties of weakly caking coal,as well as the caking index and the thickness of gum layer,are studied.Then small coke oven is used for proportioning research.On the premise of ensuring coke quality,weak cohesive coal is blended scientifically and reasonably.It has been well applied in industrial production,reducing production costs and maximizaing benefits.
