EMISSION CONTROL USING FLUIDIZED BED COMBUSTION

Cfd 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 ...

Foam Control Using a Fluidized Bed

Control of a Fluidized Bed Polyethylene Reactor

In present paper, dynamic behavior and control of a fluidized bed reactor for polyethylene production has been considered. A double active sites model for Ziegler-Natta catalysts is used for simulation of polymerization reaction. Hydrodynamic behavior of the bed is modeled using a two phase model including bubble and emulsion phases in which bubble phase has plug flow pattern with different...

GASIFICATION vs COMBUSTION OF WASTE/BIOMASS IN FLUIDIZED BED REACTORS

This paper presents a comparison of commercial fluidized bed gasifiers and combustors used to recover energy from municipal solid wastes and biomass. The work reported here is excerpted from four case studies prepared for the International Energy Agency’s Bioenergy Agreement, under Task 23 (Energy from Thermal Conversion of MSW and RDF, 1998-2000) and Task 36 (Energy from Integrated Solid Waste...

Olive Cake Combustion in a Circulating Fluidized Bed

In this study, a circulating fluidized bed of 125 mm diameter and 1800 mm height was used to find the combustion characteristics of olive cake (OC) produced in Turkey. Olive cake alone and olive cake+lignite coal mixtures were burned separately. Various olive cake/lignite coal ratios were tried. A suitable feeding mechanism of olive cake to the bed was developed. On-line concentrations of O2, S...
