Application of a Central Composite Design for the Study of NOx Emission Performance of a Low NOx Burner
Dutka, Marcin Damian; Ditaranto, Mario; Løvås, Terese (Journal article; Peer reviewed, 2015)In this study, the influence of various factors on nitrogen oxides (NOx) emissions of a low NOx burner is investigated using a central composite design (CCD) approach to an experimental matrix in order to show the applicability ... -
Cold flow characteristics of a novel bluff body hydrogen burner
Meraner, Christoph; Li, Tian; Ditaranto, Mario; Løvås, Terese (Journal article; Peer reviewed, 2018)The cold flow characteristics of a novel partial premixed bluff body (PPBB) low NOx burner, capable of operating with hydrogen as well as methane-hydrogen blends, were investigated numerically. The PPBB burner features a ... -
Concept of hydrogen fired gas turbine cycle with exhaust gas recirculation: Assessment of combustion and emissions performance
Ditaranto, Mario; Li, Hailong; Løvås, Terese (Journal article; Peer reviewed, 2015)A novel gas turbine cycle concept applicable to power plants with pre-combustion CO2 capture or integrated gasification combined cycle (IGCC) is presented. These power plants use a hydrogen rich fuel with high reactive ... -
Effects of scaling laws on the combustion and NOx characteristics of hydrogen burners
Meraner, Christoph; Li, Tian; Ditaranto, Mario; Løvås, Terese (Peer reviewed; Journal article, 2020)This paper proposes a novel bidirectional linkage between a long-term energy system model and an operational power market model. This combined modelling framework provides long-term energy system investment strategies that ... -
Emission characteristics of a novel low NOx burner fueled by hydrogen-rich mixtures with methane
Dutka, Marcin Damian; Ditaranto, Mario; Løvås, Terese (Journal article; Peer reviewed, 2015)The use of hydrogen-rich fuels may be challenging for burner designers due to unique properties of hydrogen compared to conventional fuels such as natural gas. Burner retrofit may be required to use hydrogen-enriched fuels ... -
Experimental and numerical kinetic study on charged and excited species in oxyfuel combustion for CO2 capture
Grabinski, Krzysztof Adam (Master thesis, 2016)Within the scope of the work, selected chemical kinetics and combustion issues were investigated. The first part contains a study of high temperature plasma and its po- tential usage as a working fluid in the magnetohydrodynamic ... -
Experimental and Numerical Results of a Non-DLE Aeroderivative GT Combustion System Burning Methane-Ammonia Blends at Intermediate Pressures
Ditaranto, Mario; Füri, Marc; Solvang, Sindre Ertzgaard; Saanum, Inge (Chapter, 2023)Ammonia is considered as a practical hydrogen carrier, as it can be stored in liquid form at moderate pressures and temperatures and is commonly produced and transported today. Ammonia could be used directly as a Gas Turbine ... -
Investigation of Turbulent Oxy-Fuel Jet Flames Using Raman/Rayleigh Laser Diagnostics
Sevault, Alexis; Barlow, R.S.; Dunn, M.; Ditaranto, Mario (Others, 2011) -
Laser Induced Incandescence with Long Pulse Duration
Hverven, Stine Myhre (Master thesis, 2013)Laser Induced Incandescence (LII) is a technique used to observe soot concentration and particle size in a flame. The LII signal is captured by an intensified CCD camera. Laser light impacts and heats soot particles within ... -
Lift-off of methane jet flames in O2/CO2 atmospheres
Norheim, Bård Lode (Master thesis, 2009)Turbulent jet diffusion flames and flame lift-off have been the topic of a great deal of research due to its complexity in combining both turbulent flow and combustion. The mechanisms controlling flame lift-off however, ... -
NOx emissions and turbulent flow field in a partially premixed bluff body burner with CH4 and H2 fuels
Dutka, Marcin Damian; Ditaranto, Mario; Løvås, Terese (Journal article; Peer reviewed, 2016)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 ... -
On the Scalability of a Partially Premixed Low NOx Hydrogen Burner
Meraner, Christoph (Doctoral theses at NTNU;2019:284, Doctoral thesis, 2019)Increasingly stringent regulations on nitric oxide (NOx) emissions led to the development of various low and ultra low NOx combustion technologies over the last decades. These technologies are further challenged by the ... -
On the structure of the near field of oxy-fuel jet flames using Raman/Rayleigh laser diagnostics
