设计说明
煤是我国的主要能源,,满足大、中型高炉等工业生产的需要,煤质的优劣是关键。
本次设计采用配煤煤种是气煤,肥煤和长焰煤,高温干馏条件下炼制出达到冶金焦国家二级标准。设计年处理量为40万吨,年工作365天。选用的是我国自行研制的JN43-80型焦炉,捣鼓炼焦的方法,干法熄焦工艺进行炼焦生产高质的焦炭,对此方案进行物料衡算和热量衡算,并且强调在工艺操作中注意的环节。
通过合理的配煤方案,提高配煤质量;充分考虑煤炭资源的平衡及供应情况,降低配煤成本;有效降低高炉焦比;保证配煤生产和配煤设备正常运行,实现效益最大化。
关键词:配煤指标降低成本效益最大
Design description
Coal is China's main source of energy, coking and carbonization gas and other industrial raw materials in order to get the coke of acceptable quality to meet the needs of the industrial production of large and medium-sized blast furnace, the pros and cons of coal is the key.
The design blending coal gas coal, fat coal and coking coal, refining to reach the national secondary standard metallurgical coke under high temperature carbonization conditions. The designed annual handling capacity of 40 tons, for 365 days. Selection is independently developed by China JN43-80 coke oven, fiddle coking method, dry coke quenching process of coke production of high quality coke, this program material balance and heat balance, and emphasis on the process operation Note the link.
Reasonable blending program to improve the quality of blending; take full account of the balance and the availability of coal resources, and reduce blending costs; reduce the blast furnace coke rate; to ensure the normal operation of the blending production and blending
