Examination of Parameters Affecting Heat Transfer In a Bubbling Fluidized Bed Reactor

Fluidized bed boilers have the characteristics of being economical, technological and environmentalist in terms of evaluation of low quality fuels according to conventional combustion systems. Fluid bed technology, coal, biomass, industrial and domestic waste can be burnt clean, safe and high efficiency. In this context, "fluid bed combustion" is an important option in the evaluation of our lignites with high moisture and sulfur levels, increasing the yield and reducing harmful emissions such as NOx and SO2. In the fluid bed, the sum of the drag force generated in the bed particle with the pressurized combustion air and the sum of the ambient lifting force in the upstream direction is compensated by the gravity forces formed in the downward direction and the bearing material is forced into a dense turbulent and fluid hydrodynamic behavior with unstable turbulence. This behavior forms the basis of the hydrodynamic design and the heat transfer mechanism in the fluid bed. In this study; The effect of the parameters determining the heat transfer from the immersed surface in a bubbling fluidized bed reactor was investigated experimentally under different test conditions
