Combustion Behavior of Relatively Large Pulverized Biomass Particles at Rapid Heating Rates

Combustion modelling of pulverized biomass particles at high temperatures

Biomass co-firing is becoming a promising solution to reduce CO2 emissions, due to its renewability and carbon neutrality. Biomass normally has high moisture and volatile contents, complicating its combustion behaviour, which is significantly different from that of coal. A computational fluid dynamics (CFD) combustion model of a single biomass particle is developed in this work, to predict the ...

Computational Modeling of CO/CO2 Ratio Inside Single Char Particles during Pulverized Coal Combustion

A recently developed model was used to study the CO/CO2 ratio inside a burning pulverized coal particle, to better understand the effect of bulk gas composition on the equilibrium partial pressure of reduced metal species at the surface of ash inclusions. The motivation was to improve the ability to model submicrometer particle formation by ash vaporization, as a function of furnace conditions....

Stereoscopic Camera-Based Investigation of Pulverized Solid Fuel Combustion - particle temperature, shape and burning rates

A newly developed stereoscopic camera system has been applied to measure the temperature, size and shape of burning coal and biomass particles in a lab-scale laminar flow reactor. The stereoscopic imaging method enables to measure the particle contour which can be used to determine the shape of the particle. As the camera system is constructed for two-color pyrometry, the simultaneous detection...
