Modeling the temperature in coal char particle during fluidized bed combustion
The temperatures of a coal char particle in hot bubbling fluidized bed (FB) were analyzed by a model of combustion. The unsteady model includes phenomena of heat and mass transfer through a porous char particle, as well ...
Entrainment of cold gas into turbulent premixed acetylene flame
(Combustion Science and Technology, 2001)
Entrainment of surrounding air into premixed acetylene flame leads to a change in velocity and temperature fields. In this paper the mixing process between the premixed acetylene flame and surrounding air, in different ...
Mathematical model of combustion in particulate 2-phase flow
(Heat Transfer Research, 2007)
A mathematical and numerical model of pulverized coal combustion in wide-range-use furnaces with swirl burners, i.e., within a turbulent particle-laden swirl flow in axisymmetric geometry is presented. The model is based ...
Investigation of the suitability of Serbian lignites for burning in CFBC boilers
The results of the detailed investigations of behavior of lignites Kolubara and Kovin, in fluidized bed combustion are presented in the paper. Investigation was carried out due to the interest of the Serbian Electric Power ...
SiO2 thin films obtained from silica sols by thermal spraying
(Journal of Optoelectronics and Advanced Materials, 2009)
The mechanism of the synthesis of silicon dioxide thin films on the surface of a stainless steel band substrate, by thermal spraying of a silica sol as a precursor was the subject of this work. The structural design of the ...
