热焦炉荒煤气应用于气流内热式炉实现煤低温干馏的初步设想

Notion of Hot Raw Coke Oven Gas(COG) Utilization on Inside Airflow Pyrogenation Oven to Realize Low Temperature Carbonization

以合理有效的利用焦炉荒煤气的显热为出发点,提出了利用热焦炉荒煤气作为气流内热式低温干馏炉的气体热载体的设想。通过两种不同型式的气流内热式低温干馏炉:内热式中低温热解炉和鲁奇三段炉,对这一设想技术上的可行性作了初步的定性分析,并提出了相应的改造建议。同时分析了实现这一想法可以带来的利益和存在的问题。以热焦炉荒煤气作为气流内热式炉的气体热载体进行煤低温干馏的过程实现了物理能和化学能的综合梯级利用,无论从焦化厂节约能源还是从原煤合理利用的角度来看,其在经济、环境和能量利用方面都是非常有利的。

Considering reasonable utilization of the physical heat of hot raw coke oven gas （COG）, this paper puts forward the notion of hot raw COG as hot carrier on inside airflow pyrogenation oven to realize low temperature carbonization. And through two utilization examples, in principle the technical feasibility of the notion was analyzed and the corresponding technical alteration suggestions were given. Besides, some advantages and problems of the notion were discussed. The process will realize reasonable utilization of physical and chemical energy, and bring advantages of energy, environment and economy into play. If the notion can be realized in coking plants, it will help to enhance energy and resources utilization efficiency.
