【摘要】 研究沥青岩在不同播煤风温度下的输送特性对沥青岩的利用具有重要意义。根据达西定律设计了沥青岩输送特性实验系统,该系统利用压降法测量沥青岩的初始粘结温度。实验结果表明,该样品的播煤风温度不宜超过250℃。此实验方法和装置,同样适用于研究褐煤、烟煤等高挥发分燃料的输送特性。更多还原

【Abstract】 Transfer characters of bituminous rock under different temperature are important for its utilization,in the paper we design an experimental system by Darcy’s law.The system measures pressure drop through the material column to determine the onset temperature for the sintering of bituminous rock.The experiment result shows that the temperature of fuel spreading air should be below 250 ℃.This method and systems are also used for other volatile-rich fuels such as brown coal and bituminous coal.更多还原
