Distribution Characteristics of Valuable Elements, Al, Li

Feed coal, fly ash (FA), and bottom ash (BA) were collected from a 300 MW circulating fluidized bed boiler. A mechanical screen classifier was used to separate and obtain particles with different sizes. The distribution of valuable elements, including aluminum (Al), lithium (Li), and gallium (Ga), and rare earth elements (REE) in the samples was investigated. Results indicate that the contents ...

NUMERICAL SIMULATION OF COAL GASIFICATION IN A CIRCULATING

that fluidized bed gasifiers are the most suitable for coal gasification of high ash Indian coals. The fluidized bed gasifiers can be divided into bubbling fluidized bed (BFB) and circulating fluidized bed (CFB) gasifiers. The selection of a gasifier between these two types is the next step for the designers.

Chemical-Looping Combustion with NiO and Fe2O3 in a Thermobalance and Circulating Fluidized Bed

For the chemical-looping combustion (CLC), readily available metal oxides (NiO, Fe2O3) for oxygen carriers and bentonite, TiO2, and Al2O3 for the supports of the looping materials were selected. The reactivity of the oxygen carrier particles was determined in a thermobalance reactor under the reducing (CH4) and oxidizing (O2) conditions at 923−1223 K. The reactivity of NiO is …

Circulating Fluidized Bed Combustion - an overview

In fluidized bed combustion (FBC) (Fig. 4), crushed coal, 5–10 mm in particle size, is burned in a 1000-mm-deep bed of 0.5- to 3.0-mm particles consisting mainly of additive sorbents (limestone or dolomite) and coal ash. The bed is fluidized by a blast of air through a distributor plate at the bottom of the bed.

Partitioning and transformation behavior of toxic elements

A study on toxic elements behaviors from a 330 MW coal gangue circulated fluidized bed co-combustion power plant equipped with electrostatic precipitators (ESPs) was performed.Simultaneous sampling of feed coal, bottom ash, fly ash and flue gas were implemented. Sequential chemical extraction was taken to investigate the transformation behaviors of toxic elements.
