In this paper, a kinetic-diffusion surface combustion model is examined. The model is modified such that two effects of turbulence are included: 1) enhancement of the mass transfer due to relative velocity between particles and fluid and 2) reduction of the mass transfer due to turbulence-induced...

... Additional investments to negative emission technologies, such as reforestation or bioenergy with carbon capture and storage (BECCS), are required to achieve Paris Agreement targets. Chemical-looping combustion of biomass (Bio-CLC)is an under-the-development combustion technology that could...

Globally, large private and public funds are invested into CO₂ capture and storage (CCS) research to provide the knowledge and technology required to mitigate CO₂ emissions below a sustainable level. A pertinent question to ask is whether this is the best way of spending limited resources. This...

Oxy-fuel conditions may have a considerable influence on the cement production process. This paper presents the results of a first validation work aiming to model the combustion behavior under rich CO₂ conditions. The experiments took place in a 500 kWth pulverized fuel combustion rig. A swirl...
