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 ...
متن کاملEmission characteristics of co-combustion of sewage sludge with olive cake and lignite coal in a circulating fluidized bed.
In this study, a circulating fluidized bed (CFB) of 125 mm diameter and 1800mm height was used to find the combustion characteristics of sewage sludge (SS) produced in Turkey. Sludge + olive cake, and sludge + lignite coal mixtures were burned separately. Various sludge-to-lignite coal and sludge-to-olive cake ratios (5/95, 10/90, 15/85, 20/80) were tried. On-line concentrations of major compon...
متن کاملOlive 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...
متن کاملReuse the Bed Ash from Circulating Fluidized Bed Combustion on Mortar Mixture
This paper investigates mortars consisting of various circulating fluidized bed combustion (CFBC) bed ash contents. The CFBC bed ash used in this study was obtained from Taiwan’s petroleum industry. This study presents experimental results on the flowability, compressive strength, drying shrinkage, scanning electronic microscopy (SEM) and mercury intrusion porosimetry (MIP) of mortar samples co...
متن کاملEcotoxicological assessment of ashes and particulate matter from fluidized bed combustion of coal.
Toxicity of ash and particulate matter from the gases generated in coal fluidized bed combustion (FBC) has been determined by the Microtox assay according to the standard leachate procedure. Results are compared with the polycylic aromatic hydrocarbon (PAH) content of the particulate matter, which was determined by fluorescence spectroscopy. Although PAHs are considered highly toxic compounds, ...
