Jul 20, 2018· High moisture content is the main restraint for the application of lignite coals. Moisture content of coal causes many difficulties during processing, storage, transport, grinding, and combustion. The high moisture content considerably reduces the CV and combustion efficiency of the coal. It also results into higher heat loss in the exhaust gas.

Jan 01, 2016· For pulverized lignite, its high moisture content has an important influence on interparticle cohesion . Therefore, to reveal the effect of moisture content on dense-phase pneumatic conveying of pulverized lignite, the relationships among moisture content, interparticle cohesion, particle flowability and the fluidization quality should be
Jun 15, 2020· Air-dried raw lignite was crushed using a lab-scale roll crushing mill and screened into the one specific required size fraction, i.e., −1.25 +0.71 mm using a standard sieve. Shengli lignite was characterized by high moisture, high volatility, and low calorific value. The proximate analysis of Shengli lignite is given in Table 1.
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.
