Prb Coal Degradation Causes And Cures

In general, the moisture content of coal increases with decreasing rank. For example, PRB coal has a higher inherent moisture content than bituminous B type coal. The oxidation of pyretic sulfur is also a heat producing reaction. The heat generated can cause the temperature of the surrounding coal to increase, thus increasing the rate of oxidation.

Summary. Removal of inherent moisture from run-of-mine lignite was tested by lock-feeding the lignite, which was previously sized by screening into 25 kg autoclaves. High pressure, up to 4.053 MPa 588 psi, saturated steam was then introduced into the pressure reactor. Reaction time, pressure, temperature and depressurization rates were strictly controlled for each reactor test run.
