摘　　要：生物质型煤具有煤、生物质单独所不具备的可固硫、不冒烟、高热值、高挥发性的综合特性.本文选用陕西彬长烟煤及当地生物质秸秆为原料,制备出纯生物质型煤并对该型煤进行物理性能检测,结果表明:纯生物质型煤抗压强度、跌落强度较高,但浸水强度和复干强度差;通过加入不同量淀粉及无机固化剂对型煤制备工艺进行改进,得到物理性能较好的生物质型煤,得出型煤中淀粉的最佳用量为10%、MgO最佳用量4.5%、MgCl2最佳用量为3.0%.Biomass compound coal has some special properties such as sulfur fixation, no smoke, higher calorific value,higher volatilizes. This experiment selected Shaanxi Binchang＇ coal and local biomass straw as the experimental raw material produced the pure biomass bri- quette and test its physical performance. The results showed that： Biomass compound coal is well in higher compression strength, strength drop, but the flooding strength and re-dry strength is poor. By adding various different amounts of starch and inorganic curing agent improve the process of making biomass briquette, which had the higher physical properties. Besides, by comparing to learned in the coal briquette starch optimum amount of 10%, MgO optimum amount of 4.5 %, MgC12, optimum amount of 3.0 %.
