Carbonation Behavior of Fly Ash with Circulating Fluidized Bed Combustion (CFBC)

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 ...

Reuse 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...

Carbonation of Brine Slurried Size Fractionated Coal Combustion Fly Ash

Coal combustion by-products such as fly ash (FA), brine and CO2 from coal fired power plants have the potential to impact negatively on the environment. Reaction of CO2 with FA/ brine slurry can potentially provide a viable route for CO2 sequestration through formation of mineral carbonates. Fractionated FA has varying amounts of CaO which not only increases the brine pH but can also be convert...

Studies on Ash Behavior during Co-Combustion Of Paper Sludge in Fluidized Bed Boilers

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...
