【摘要】 基于鄂尔多斯市各地区煤质特性指标差异大、煤炭资源优势互补的特点,对鄂尔多斯市优质低灰熔融温度煤与高灰熔融温度煤、低发热量煤与高发热量煤、高硫煤与低硫煤进行了实验室的配煤试验研究。试验研究结果表明:低灰熔融温度优质煤配入少量高灰熔融温度煤,其煤灰熔融温度显著提高;采用3种原料煤配煤有助于显著降低高硫煤中的全硫含量。更多还原

【Abstract】 Based on the difference of coal quality characteristics indexes of various places of Ordos area is significant,and the coal resources have complementary advantages,the coal blending experimental research for high-quality,low ash melting temperature coal and high ash melting temperature coal,low-calorific value coal and high-calorific value coal,the high-sulfur coal and low-sulfur coal from Ordos city was done.The experimental research results showed that:if the low ash melting temperature and high quality coal was mixed with a small amount of high ash melting temperature coal,the ash melting temperature would be increased significantly;the use of three kinds of raw coal for coal blending could make the total sulfur content in high sulfur coal reduced.更多还原
