Capturing CO2 from Biogas Plants
CFD modeling and thermodynamic analysis of a concept of a MILD-OXY combustion large scale pulverized coal boiler
A concept of a large scale pulverized coal boiler working in the oxycombustion mode has been proposed. The combustion chamber has been designed using the Moderate and Intensive Low-oxygen Dilution (MILD) combustion technology. By screening CFD solutions of several geometric configurations the best o...
Oxy-fuel burner investigations for CO2 capture in cement plants
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 burne...
Design of the experimental rig for retrieving kinetic data of char particles
A new concept for evaluating chemical kinetics data of combustion of coal char particle is proposed. The experimental rig based on the measurement of mass loss of the char particle during the combustion process has been designed and built. The char particles are dropped into a laminar carrier gas st...
Predicting Chemical Flame Lengths and Lift-off Heights in Enclosed, Oxy-Methane Diffusion Flames at Varying O2/CO2 Oxidizer Dilution Ratios

Visualization system for the measurement of size and sphericity of char particles under combustion conditions
Advanced visualization systems are used in many engineering applications where information about particle size and position plays critical roles. In practice, the manual detection and following of individual or groups of particles is not feasible; an automated computational method must be used. Devi...
NOx emissions and turbulent flow field in a partially premixed bluff body burner with CH4 and H2 fuels
The increased need for fuel flexibility and CO2 capture solutions (CCS) in the power and industrial sectors has led to higher focus on hydrogen containing fuels. The high reactivity and combustion temperature in hydrogen flames are a source of high nitrogen oxides (NOx) and a barrier to the implemen...
Fjerner CO2 fra naturens kretsløp
Lær deg uttrykket «karbonnegativ teknologi», først som sist. Det har nemlig blitt en snakkis i teknologikretser. Her får du forklaringen på hvorfor....
