Improvement of the turn-down ration of gas turbines by auto thermal on board syngas generation
Journal of the Global Power and Propulsion Society, 2017 The low reactivity of natural gas leads to a sudden increase of carbon monoxide (CO) and unburned hydrocarbons (UHC) emissions below a certain load level, which limits the part load operation range of current utility gas turbines in combined cycle power ...

Physics of SNeIa and Cosmology
, 2003 We give an overview of the current understanding of Type Ia supernovae relevant for their use as cosmological distance indicators. We present the physical basis to understand their homogeneity of the observed light curves and spectra and the observed ...

Type Ia Supernova Explosion Models: Homogeneity versus Diversity [PDF]
, 2000 Type Ia supernovae (SN Ia) are generally believed to be the result of the thermonuclear disruption of Chandrasekhar-mass carbon-oxygen white dwarfs, mainly because such thermonuclear explosions can account for the right amount of Ni-56, which is needed ...

Experimental study of the effect of cycle pressure on lean combustion emissions [PDF]
Experiments were conducted in which a stream of premixed propane and air was burned under conditions representative of gas turbine operation. Emissions of NOx, CO, and unburned hydrocarbons (UHC) were measured over a range of combustor inlet temperature,

Effect of exhaust gas recirculation on emissions from a flame-tube combustor using Liquid Jet A fuel [PDF]
The effects of uncooled exhaust gas recirculation as an inert diluent on emissions of oxides of nitrogen (NO + NO2) and on combustion efficiency were investigated.
