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...

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...

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...
Demonstration Plant and Combustion System for an Oxy-Fuel Gas Turbine Cycle
A semi-closed oxy-fuel retrofit gas turbine demonstration plant (DEMOXYT) is described and preliminary results of the oxy-fuel burner under relevant conditions are presented. The plant consists of a 100 kWel radial turbine with a pressure ratio of 4.25, featuring a recuperator, to which a specific o...
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...
