An experimental study of temperature of burning coal particle in fluidized bed
(Amer Chemical Soc, Washington, 2006)
The purpose of this study was to investigate the temperature of coal particle during combustion in fluidized bed (FB). It is necessary to know the coal particle temperature in order to predict kinetics of chemical reactions ...
Numerical Prediction of Pulverized Coal Flame in Utility Boiler Furnaces
(Amer Chemical Soc, Washington, 2009)
In optimization of a utility boiler furnace operation, special attention is given to the flame geometry and position. As an illustration of possibilities for application of mathematical prediction and numerical experiment ...
Effect of Excess Air Ratio and Temperature on NOx Emission from Grate Combustion of Biomass in the Staged Air Combustion Scenario
(Amer Chemical Soc, Washington, 2011)
The combustion of biomass, in this case demolition wood, has been investigated in a grate combustion multifuel reactor. In this work a temperature range of 850-1000 degrees C is applied both for staged air combustion and ...
Experimental and Numerical Investigation of the Primary Fragmentation of a Lignite during Fluidized-Bed (FB) Devolatilization
(Amer Chemical Soc, Washington, 2015)
The paper presents a comparison between experimental and model results of primary fragmentation of a lignite coal in a fluidized bed (FB). In the experiments, the char particle size distribution and the general indicators ...
Prediction of Coal Primary Fragmentation and Char Particle Size Distribution in Fluidized Bed
(Amer Chemical Soc, Washington, 2013)
The combination of temperature gradient and volatile release has been identified as the main cause for primary fragmentation (breakage of fuel particles during devolatilization). A mathematical model of the primary ...
Numerical Analysis of NOx Control by Combustion Modifications in Pulverized Coal Utility Boiler
(Amer Chemical Soc, Washington, 2012)
Considerable research efforts focus on modeling NOx formation/destruction and predicting NOx emission so that it can be controlled. A motivation for this numerical study was to examine the efficiency of combustion modifications ...
