During hypothetical core melt accidents steam and hydrogen can be released into the air filled containment of pressurized water reactors (PWR). Without counter measures flammable mixtures may form and cause combustion loads that could threaten the integrity of the containment. German PWR’s are now equipped with passive catalytic recombiners so called PARs (passive autocatalytic recombiners). Th...

The concentrations of 16 US-EPA criteria polycyclic aromatic hydrocarbons (PAHs) were monitored during different seasons at six different cities/ locations in the northern part of Belgium. Pressurized liquid extraction was used for the fast recovery of PAHs from quartz fibre filters (QFFs) and polyurethane foams (PUFs) in less than 30 minutes with minimum solvent consumption prior to their anal...

Pressurized oxy-coal combustion has received wide attention recently due to its potential of high efficiency and low cost in CO 2 capture. However, there is still a significant knowledge gap on the effects pressure oxy-char behaviors. In this study, experiments were carried out pressurized fluidized bed combustor, oxygen concentration burnout time, reactivity temperature char particles investig...

Post-combustion carbon capture is a key component of the fight against global warming and climate change. Amine stripping is currently the leading post-combustion technology, and indeed is employed at the World’s first and only commercial scale carbon capture project applied to a power plant, at Boundary Dam, Canada. Normally, regeneration of the spent amine solution is achieved by stripping wi...

Flashing or thermodynamic breakup of a liquid jet occurs when a pressurized subcooled or saturated liquid is released to a lower pressure, resulting in violent vapor nucleation, expansion, and break up of the liquid phase. Flashing is known to produce very fine droplet atomization, often not possible by traditional mechanical means. In this work, flashing atomization is introduced in a spray bu...

The new technique ‘Multi-Intensity-Layer PIV’ was applied to a gas turbine combustor to detect the instantaneous droplet distribution and its behavior. Mie scattering theory is applied to the conventional Particle Image Velocimetry and the technique enables us to detect the instantaneous planar droplet velocity and size information. This M-PIV technique was evaluated with a generally used indus...
