Fluidised bed drying of soybeans.
The fluidised bed drying characteristics of soybeans at high temperatures (110-140 degrees C) and moisture contents, 31-49% dry basis, were modelled using drying equations from the literature. Air speeds of 2.4-4.1 m/s and bed depths from 10 to 15 cm were used. The minimum fluidised bed velocity was 1.9 m/s. From a quality point of view, fluidised bed drying was found to reduce the level of ure...
متن کاملAn Improved Sparge Pipe Air Distribution System for a Fluidised Bed Combustor
The purpose of the air distribution system in a fluidised bed combustor is to provide a reasonably uniform spread of combustion air over the entire horizontal cross-sectional area of the bed. One of the simplest, and hence cheapest, forms of air distributor is the sparge pipe design, in which an array of horizontal pipes is fitted at the base of the bed. Combustion air is then supplied to one e...
متن کاملMelt Granulation in Fluidised Bed: Screening of the Process Variables by Factorial Design
In recent years, the interest in melt granulation has increased due to the advantages of this technique respect to traditional wet granulation; utilizable equipments for melt granulation are high-shear mixer and fluidised bed [1]. The aim of the study was to evaluate, by asymmetrical factorial design [2], the contribution of some variables on the in situ melt granulation process performed in fl...
متن کاملA semi-empirical model for pressurised air-blown fluidised-bed gasification of biomass
A process model for pressurised fluidised-bed gasification of biomass was developed using Aspen Plus simulation software. Eight main blocks were used to model the fluidised-bed gasifier, complemented with FORTRAN subroutines nested in the programme to simulate hydrocarbon and NH3 formation as well as carbon conversion. The model was validated with experimental data derived from a PDU-scale test...
متن کاملEmissions modeling of fluidised bed co-combustion of poultry litter and peat.
Gaseous emissions from the fluidised bed co-combustion of 50% w/w chicken litter and peat were monitored and recorded. Emission data were used to create a dispersion model for a proposed site on a poultry farm in Ireland. Variables within the combustion unit influenced both combustion and emission levels of pollutants such as SO(2) and NO(x), CO. Concentrations of atmospheric pollutants decreas...
