Effect of exhaust gas recirculation on emissions from a flame-tube combustor using Liquid Jet A fuel [PDF]

open access: yes
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.

Physics of SNeIa and Cosmology

open access: yes, 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 ...

Oil heating furnace control based on calculation of the heat balance

open access: yesИзвестия высших учебных заведений: Нефть и газ
The oil heating furnace is a crucial component of the oil treatment unit and can utilize associated petroleum gas as fuel. However, gases of varying compositions require different amounts of air for complete combustion.

Exhaust emissions from a premixing, prevaporizing flame tube using liquid jet A fuel [PDF]

open access: yes
Emissions of nitrogen oxides, carbon monoxide, and unburned hydrocarbons were measured in a burner where liquid Jet A fuel was sprayed into the heated air stream and vaporized upstream of a perforated plate flameholder. The burner was tested at inlet air

Ignition of Deflagration and Detonation Ahead of the Flame due to Radiative Preheating of Suspended Micro Particles [PDF]

open access: yes, 2015
We study a flame propagating in the gaseous combustible mixture with suspended inert particles. The gas is assumed to be transparent for the radiation emitted by the combustion products, while particles absorb and re-emit the radiation. Thermal radiation

Effects of Hydrogen-Rich Gas Injection on Combustion Characteristics in Blast Furnace Raceway and Thermal Load of Tuyere: A Numerical Simulation Study

open access: yesMetals
Hydrogen-rich gas (HRG) injection is a promising low-carbon solution for blast furnace ironmaking. This study conducted numerical simulations in the lower part of a blast furnace to analyze the combustion behavior of coinjected coke oven gas (COG) and ...

Experimental Investigation into the Combustion Characteristics of Propane Hydrates in Porous Media

open access: yesEnergies, 2015
The combustion characteristics of both pure propane hydrates and the mixtures of hydrates and quartz sands were investigated by combustion experiments. The flame propagation, flame appearance, burning time and temperature in different hydrate layers were
