Kinetics of woodchips char gasification has been examined. Steam and CO2 were used as the gasifying agents. Differences and similarities between kinetics of steam gasification and CO2 gasification have been discussed. Comparison was conducted in terms of gasification duration, evolution of...

Gasification of polyethylene (PE) and woodchips (WC) mixtures have been investigated in a semi-batch reactor, using high temperature steam as the gasifying agent. The reactor temperature was maintained at 900 °C. The ratio of PE-WC was varied from 0% to 100% in 20% intervals....

Characteristics of syngas from the pyrolysis and gasification of food waste has been investigated. Characteristic differences in syngas properties and overall yields from pyrolysis and gasification were determined at two distinct high temperatures of 800 and 900 °C. Pyrolysis and...

Steam gasification of sugarcane bagasse has been investigated. A semi batch reactor with a fixed amount of sugarcane bagasse sample placed in steady flow of high temperature steam at atmospheric pressure has been used. The gasification of bagasse was examined at reactor and steam temperatures of...

Lignite pyrolysis and gasification has been conducted in a semi batch reactor at reactor temperatures of 800–950°C in 50°C intervals. CO2 has been used as the gasifying agent for gasification experiments. The objective of this investigation is to understand the mechanism of syngas evolution...

Combustion systems results in high pollution and low performance due to lack of uniform thermal and chemical behavior in the entire reactor zone. Localization of multiple acoustic sources using an array of microphones and time difference of arrival (TDOA) method is examined. Adaptations of such...

Spectroscopic examination of the emission spectra of excited species in hydrogen/air flames both without and with H2S addition and in hydrogen sulfide/oxygen flame are conducted. The baseline case of hydrogen/air flame showed one distinct global peak of OH* at 309.13 nm. However, higher...

Reaction behavior of H2S/O2 under different equivalence ratios in methane/air flames is examined. Three equivalence ratios extending from fuel-lean ([Phi] = 0.5), stoichiometric ([Phi] = 1.0), to fuel-rich (Claus condition, [Phi] = 3.0) are examined. The results revealed that...

Combustion in small scale devices poses significant challenges due to the quenching of reactions from wall heat losses as well as the significantly reduced time available for mixing and combustion. In the case of liquid fuels there are additional challenges related to atomization, vaporization...

The dynamics of premixed propane-air flame in a meso-scale ceramic combustor has been examined here. The flame characteristics in the combustor were examined by measuring the acoustic emissions and preheat temperatures together with high-speed cinematography. For the small-scale combustor, the...
