Investigation of the radiative heat release factor of premixed oxy-syngas flames
A significant part of the United States is being powered by combustion devises relying on coal since it is abundant and is a high emitting source of electricity per unit energy, however; the burning of this fuel is responsible for a significant contribution for the pollutant emissions causing global warming. Because coal is one of the main sources of energy in the U.S. and around the globe, the scientific community has been investigating ways to meet current and future governmental emission requirements. It is now well established that radiating heat from the flame is a major contributor of the heat flux going into the combustor walls making this issue of major interest in the design field. Oxy-fuel is a promising combustion technique that would allow a simplified carbon capture and storage process and allow for the use of coal as a source of energy. In order to be able to retrofit the existing technology with oxy-fuel combustion or design new combustor systems, a deeper understanding of factors like heat transfer and combustion kinetics is needed to prove the feasibility of this technology. Motivated by the change in the radiative properties when conducting oxy-syngas combustion and the much needed fundamental oxy-syngas combustion characteristics data, this thesis work aims to contribute to the study of the global radiation of oxy-syngas combustion. The effects of CO2 acting as a diluent, percentage of H2 in the fuel, firing input and the effects of equivalence ratio on the flame's radiative heat release are investigated.
