Abstract The classification performance of model coal mill classifiers with different bottom incoming flow inlets were experimentally and numerically studied. The flow field adjacent to two neighboring impeller blades were measured using the particle image velocimetry technique. The results showed that the flow field adjacent to two neighboring blades with the swirling inlet was significantly different from that with the non-swirling inlet. With the swirling inlet, there was a vortex located bet...

Abstract Combustion and NOx emission characteristics of a bituminous coal (BC) blended with semi-coke (SC) are investigated using a Thermogravimetric Analyzer (TGA) and Drop Tube Furnace (DTF) at a different SC blending ratio Xsc. TGA results show that BC and SC have similar mass loss patterns but BC-SC blends have a second trough on their DTG curves. The addition of semi-coke increases ignition and burnout temperatures of the blends, but barely affects the burnout rate. Within 95% mass loss, th...

The effect of rotation of the stagnation surface on the nanoparticle deposition in the flame stabilizing on a rotating surface (FSRS) configuration was numerically assessed using CFD method. The deposition properties including particle trajectories, deposition time, temperature and surrounding O2 concentration between the flame and stagnation surface were examined. The results revealed that although flame position is insensitive to the surface rotation, the temperature and velocity fields are re...
