At room temperature, CO2 is transparent in the ultraviolet (UV) at wavelengths longer than 205 nm; however, at temperatures above 1000 K the CO2 absorption cross-section becomes significant in the region between 200 and 320 nm. Because CO2 is a major product of hydrocarbon combustion and because both the magnitude of the absorption cross-section and the shape of the UV absorption spectrum vary ...

In thermal power station, pulverized coal furnace is widely used. It requires the chamber of furnace holding steady uniform flame, and ensureing that strong full combustion. This study has developed a neural network ensemble model to perform the judgement of combustion diagnosis based on the spectral distribution of the light intensity pulse signal of the flame. Compared with the single neural ...

Non-deforestation fire – i.e., fire that is typically followed by the recovery of natural vegetation – is arguably the most influential disturbance in terrestrial ecosystems, thereby playing a major role in carbon exchanges and affecting many climatic processes. The radiative effect from a given atmospheric CO2 perturbation is the same for fire and fossil fuel combustion. However, major differe...

Laser-induced breakdown is used for quantitative gas property measurements (gas density and ethylene fuel concentration) in a cavity flameholder in a supersonic crossflow. A plasma is produced by a focused laser beam (Nd:YAG, 532 nm) in the cavity to measure gas properties at the location of the plasma and to ignite cavity flames. Plasma energy (PE), defined by the laser pulse energy absorbed/s...
