摘 要: | 为了提高同忻煤炭价值,丰富产品结构,保证产品质量,提高经济效益,根据同忻原煤煤质特点,结合市场需求情况,研究了同忻矿原煤出高热量1/3焦煤的可行性,确定了兼顾优质动力煤和1/3焦煤产品的灵活洗选工艺。结果表明:新工艺兼顾生产1/3焦煤和优质动力煤的灵活生产方式,可根据市场需求实现快速灵活转换,丰富了产品种类,提升了企业竞争力和综合盈利能力。在生产1/3焦煤时,中煤及其他副产品可与一期选后精煤配煤,得到满足销售需求的动力混煤,进一步提高了同忻煤炭价值。

Abstract: | In order to improve the value of coal in Tongxin,enrich product structure,ensure product quality and increase economic efficiency,according to the raw coal features and the market demand,the feasibility of producing 1/3 coking coal from Tongxin raw coal was studied,finally,a flexible washing process of producing high-quality thermal coal and low-ash clean coal products was finalized.The results show that the new process can take into account the flexible production methods of producing 1/3 coking coal and high-quality thermal coal,can achieve rapid and flexible conversion according to market demand,enrich the product range,and enhance the company's competitiveness and comprehensive profitability.When producing low-ash clean coal,the Middle coal and other by-products can be blended with the first stage cleaned coal to obtain a blended coal that satisfies the demand for sales,further increasing the value of coal in Tongxin. |
