Factors 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 کاملSimultaneous adaptive decoupling and model matching control of a fluidized bed combustor for sewage sludge
The major difficulties in designing a controller for the fluidized bed combustor for sewage sludge result from the following reasons: 1) The dynamical behavior of the plant is highly unknown and the experimental data only render a coarse model; 2) the combustion process shows large time-delay; and 3) the plant model is a stiff differential equation because the parameter values among the subsyst...
متن کاملRobust Experimental Design/Regression Model Development for Fluidized Bed Combustor (FBC) Design and Manufacturing
The hydrodynamic effect of varying operating parameters in the Fluidized Bed Combustor (FBC) has been of interest to FBC design and manufacturing. Some experiments to investigate the gas/particle flows in the gaseous fluidized bed were performed with laser-based Phase Doppler Particle Analyzer (PDPA) to measure the rise velocity of the fluidizing particles. The robust experimental design method...
متن کاملEffects of Biomass Share on So2 and Nox Emissions in a Circulating Fluidized Bed Combustor
In this study, effect of biomass share on co-combustion of coal and biomass in a circulating fluidized bed is investigated by previously developed model. SO2 and NOx emission predictions of the model are compared with test results obtained from the laboratory-scale 30 kW (thermal) atmospheric test unit of 0.86 m i.d. and 7 m tall riser data published in the literature. Simulation results show t...
متن کاملHydrodynamics of a fluidized bed co-combustor for tobacco waste and coal.
The fluidization characteristics of binary mixtures containing tobacco stem (TS) and cation exchange resin (a substitute for coal) were studied in a rectangular bed with the cross-section area of 0.3 × 0.025 m(2). The presence of herbaceous biomass particles and their unique properties such as low density and high aspect ratio resulted in different fluidization behaviors. Three fluidization vel...
