Development of a system approach for adaptation of current and design of new combustion equipment for low-carbon and sustainable energy

Stať ve sborníku mimo WoS a Scopus

The transition to low-carbon and sustainable energy is essential for reducing greenhouse gas emissions and ensuring energy security. This study introduces a system approach for adapting existing and designing new combustion equipment under new conditions. A thermodynamic analysis based on the T-Q diagram highlights key differences when implementing low-carbon and sustainable fuels, including increased thermal loads in hydrogen-based fuels and lower flame temperatures in biomass co-firing. An initial formulation of a structured system approach is proposed, identifying four critical areas: fuel preparation and transport, combustion process, heat transfer changes in the radiation chamber and convection section and waste heat utilization. Each area requires consideration and/or computational validation to address various risks. The findings emphasize the necessity of a systematic evaluation to maintain safe and reliable operation under new combustion conditions. The proposed framework provides a foundation for future studies in which the system approach should be perfected.
