Lumped modeling of bubbling fluidized beds for high‐temperature processes

AIChE Journal, EarlyView.
Abstract Bubbling fluidized beds (BFBs) have been a source of study for multiple decades. Among other applications, they can be used as scalable reactors for the conversion of biomass and waste resources to fuels. Several experimental and computational studies have been devoted to correlating the interplay of hydrodynamics and heat and mass transfer in

Pulverised biomass and coal co-firing simulation using computational fluid dynamics :A numerical investigation into the aerodynamics of non-spherical particles and full scale combustion for pulverised fuel applications [PDF]

, 2012
Recent national and international emissions legislation, in particular sulphur-dioxide, and the rapid depletion of fossil fuels are forcing power producing industries to look at various alternatives, such as biomass and co-firing techniques.

Coal Without Combustion [PDF]

Mechanical Engineering, 2007
This article focuses on various researches that have been undertaken to study and test use of fuel cells instead of boilers for cheap and clean electricity production. One of the most ambitious projects is the Solid State Energy Conversion Alliance (SECA), created by the U.S. Department of Energy to clear the technical hurdles that have kept fuel cells

High-temperature thermal storage-based cement manufacturing for decarbonization

Carbon Neutrality, 2022
Cost-effective CO2 capture is essential for decarbonized cement production since it is one of the largest CO2 emission sources, where 60% of direct emissions are from CaCO3 decomposition and 40% are from fuel combustion.
