Mechanically Treated Fly Ash from Fluidized Bed

Fly ash generation in fluidized bed combustion (FBC) is a critical issue in many countries due to its disposal is becoming increasingly restricted and expensive. Because of this, there is a demand for applications in which these types of fly ashes could be utilized efficiently. One promising use for FBC fly ashes is as a cement replacement material in mortar and concrete.

Review on Reactor Configurations for Adsorption

2021-3-5 · Adsorption-based CO2 capture has enjoyed considerable research attention in recent years. Most of the research efforts focused on sorbent development to reduce the energy penalty. However, the use of suitable gas–solid contacting systems is key for extracting the full potential from the sorbent to minimize operating and capital costs and accelerate the commercial deployment of the technology

Understanding Refractory Failure—A New Perspective

Refractory has always been an integral part of steam-generating boilers. In the steam-generating industry, refractory materials are used for filling gaps and openings to help keep the fire inside the fire box, for lining ash hoppers (wet and dry) that collect ash and slag, and for the protection of lower furnace wall tubes inside fluidized bed, cyclone-fired, or refuse-derived fired boilers.

Ash deposition behavior of a high-alkali coal in

High alkali and alkali earth metals (AAEMs) content in coal causes severe slagging and fouling during combustion in a boiler. In this study, the ash deposition behavior of a high-alkali coal at different bed temperatures and the effect of kaolin were investigated in a 30 kW circulating fluidized bed (CFB) test system using an ash slagging probe and deposition probe.

Ashes from fluidized bed combustion of residual

Although bottom ash (BA) [or mixtures of bottom and fly ash (FA)] from clean biomass fuels is currently used as liming agent, additive for compost, and fertilizer on agricultural and forest soils in certain European countries, in several other countries most of the ashes are currently disposed in landfills. This is due to both a lack of a proper classification of the materials and of
