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 کاملA 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 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 کاملDynamic model of NOx emission for a fluidized bed sludge combustor
Sludge incineration in fluidized bed is a very complex process, producing gaseous pollutants (carbon monoxide (CO) and nitrogen oxides (NOx)). The legislative norms need to be respected in spite of variations of sludge in composition and in quantity. The NOx formation, due to lots of chemical reactions from sludge nitrogen, is partly unknown. This paper deals with the design of a dynamic model ...
متن کاملIgnition and Flame Stabilization of a Strut-Jet RBCC Combustor with Small Rocket Exhaust
A Rocket Based Combined Cycle combustor model is tested at a ground direct connected rig to investigate the flame holding characteristics with a small rocket exhaust using liquid kerosene. The total temperature and the Mach number of the vitiated air flow, at exit of the nozzle are 1505 K and 2.6, respectively. The rocket base is embedded in a fuel injecting strut and mounted in the center of t...
