Scientific research

For 10 years I worked scientifically at the TU Clausthal and for a year at thyssenkrupp Industrial Solutions. I am the laureate of the NAWA Polish Returns 2019 no. PPN / PPO / 2019/1/00023, which allowed me to return to Poland and build a research team.

My scientific and research interests are related to the numerical description of physicochemical processes of fuel conversion and phenomena related to fuel technology. During my scientific career so far, most of the publications and projects I was involved in concerned the following areas:

• testing and mathematical modeling of the coal, biomass and waste gasification process,
• numerical simulations of the solid fuel combustion process in low-power boilers,
• increasing efficiency and reducing the emission of harmful substances by optimizing the combustion chamber design of low-power boilers,
• testing and modeling the process of co-combustion of coal and gas from biomass gasification,
• reduction of nitrogen oxide emissions during the combustion of solid and gaseous fuels,
• mathematical modeling of the physicochemical coal conversion process and coke production,
• optimization of the structure of coking ovens and their heating lines,
• using the reverse procedure in physicochemical problems,
• modeling of heat transport by means of thermal radiation,
• thermogravimetric and thermovolumetric analysis and their mathematical description,
• industrial processes' simplified models development for optimization and automation,
• gas chromatography.
