The residence time distribution (RTD) approach was used to characterize the flow and mixing behavior of burners. This analysis consists of injecting an inert gaseous tracer into the feed and measuring its change in concentration at various detection points. The responses are then used to characterize the flow behavior and, thus, the local mixing in...

Many efforts have been done over time to enhance the efficiency of automobiles, but an important fraction (about 80 %) of the energy created by fuel combustion is still wasted through exhaust gas and to the coolant. Extracting useful heat from the waste carried by exhaust and converting it into electricity by using thermoelectric devices seems very...

Supercritical Water Oxidation (SCWO) is the process of complete destruction of toxic and hazardous organic wastes in a compact, totally enclosed system through oxidation in water brought to temperatures and pressures above its critical point: 374 °C and 218 atm.

The emissions of polychlorinated-p-dibenzodioxins (PCDD) and dibenzofurans (PCDF) from waste combustion show a close correlation with the emissions of chlorinated benzenes or phenols, which could therefore be used as indicators for easier, faster and cheaper prediction of the potential dioxin emission levels. Using contemporary analytical methods,...

Dioxins, formed in any combustion process where carbon, oxygen and chlorine are present, are a subject of major interest due to their toxicity. Their measurement is very expensive and time consuming. In order to optimize the combustion process, on-line measurements of pollutants must be done. The use of surrogate compounds instead of dioxins seems...

As the quality of life increases and thus the demands for clean water, ensuring water purity and conservation became increasingly important. Water quality rules are more stringent, complex, and costly, to curb the tendency to use it irrationally. As a result, most companies have to clean their water both before and after they use it, since the harm...

Enhancement of the heat transfer is done, in many industrial applications, by permanent change of the fluid flow, as in spiral, compact or coiled tube heat exchangers. The Dean vortices, which appear as a result of the secondary flow, are responsible for the increase of local turbulence, and thus, the decrease of probability of stagnant zone develo...
