潞安粉煤成型技术的研究

Research on briqnetting technology of Luan fine coal

结合潞安粉煤的特点,研究成功一种新的复合粘结剂,制出了抗压强度高、热稳定性好、防水性强的造气型煤。型煤制备工艺简化,不需要烘干工序。已取得了工业性成型试验成功,为扩大潞安粉煤的有效利用提供了一条技术途径。

According to the characteristics of Luan fine coal, a new compound binder was developed in this study. It has been tested successfully to use Luan fine coal with this binder to produce briquettes for gasification with high mechanical strength, high thermal stability and high waterproof property. The briquetting technology was simplified because of no needing of thermal dry process. Luan briquettes were successfully produced in an industrial test. This success provides a technical approach for expanding efficiencial utilization of Luan fine coal.
