Fuel Particle Conversion of Pulverized Biomass during ...

Oct 11 2012 · Three experimental parameters were examined: reaction temperature (1073 and 1273 K); particle size (125250 250500 and 5001000 m); and the length of reaction zone (650 and 1885 mm). The scanning electron microscopic (SEM) images showed that biomass swelled during heating and shrank during initial stage of pyrolysis.

Fuel Particle Conversion of Pulverized Biomass during ...

The scanning electron microscopic (SEM) images showed that biomass swelled during heating and shrank during initial stage of pyrolysis. Then char morphology transformed to cenospheres after the plastic stage. The yields of solid residue from the experiments were reasonably predicted by particle simulation.

Shape and size transformations of biomass particles during ...

Feb 01 2020 · The shape size and density of the particle is important for fluid dynamic modeling as it can affect the trajectory and residence time of the fuel particle inside the boiler . Large particle size implies ignition delay and longer burnout time and therefore higher amount of carbon in ash in a furnace. The monitoring and control of fuel particle size distribution is

Shape and size transformations of biomass particles during ...

Following devolatilization during the remaining char combustion more pronounced changes in the size and shape of the particle are apparent. In most cases the shrinking char becomes more rounded as the char particle partially melts and contracts due to surface tension. This transformation is more distinct in some of the biomass samples.
