A model of a bubbling fluidized bed combustor oriented to char mass estimation
Fluidized bed techniques are employed in coal combustion power plants, because they allow for the use of low-quality fuel and result in low pollutant emissions. The most important dynamical difference between fluidized beds and normal combustion chambers, is that the former are characterized by a significant loading of carbon, usually absent in conventional plants. Fluidized beds are remarkably...
متن کاملCombustion of some Thai agricultural and wood residues in a pilot swirling fluidized-bed combustor
This paper reports a comparative study of burning Thai rice husk, sunflower shells and fine rubberwood sawdust as well as co-firing of the sawdust and shredded eucalyptus bark in the swirling fluidizedbed combustor (SFBC). All experiments for firing individual fuels were performed for the combustor heat input of ∼300 kWth. However, in the co-firing tests, the fuel mixture was delivered at a fix...
متن کاملCombustion behaviour of Olive pruning/animal manure blends in a fluidized bed combustor
Olive pruning and animal manure blends were burned in a fluidized bed system, in order to investigate their valorization for thermal energy production. Combustion performance was studied in terms of efficiency and emissions under various operating conditions. Both fuels burned mostly within the bed. The maximum temperature of animal manure was 50 °C lower than that of olive pruning, however eff...
متن کاملFactors Affecdngthe Performance of a Codisposal Atmospheric Fluidized-bed Combustor
The history of fluidized bed technology dates back 60 years. Gasification of pulverized coal in the Winkler process during the 1920's marked the beginning of fluidized bed application. Consider ,able work done during World War II by U.S. oil companies to improve the catalytic cracking of kerosene led to the development of the Fluid Catalytic Cracking process. Fluidized bed technology later exp...
متن کاملCfd Analysis of Circulating Fluidized Bed Combustion
In this paper computational analysis of circulating fluidized bed combustion using the fluent software is analysed. This work is concerned about gas–solid two-phase mixtures flowing upwards through the fast beds. The procedures studied are applicable to all types of fluidized-bed boilers. The type of information resulting from various ways of analyzing the pressure and temperature in fluidized ...
