Thermodynamische Modellrechnungen zur Entwicklung korrosionsbeständiger keramischer Werkstoffe für den Flüssigascheabscheider in kohlenstaubbefeuerten Energieanlagen
… with molten slags of hard coals in the liquid ash separater of coal combustion plants. As a result of the present thermodynamic calculations as well as the experimental findings materials based on chromcorundum show a safisfactory corrosion resistance to molten slag of hard coals because of the …

Biomass characterization and reduced order modeling of mixed-feedstock gasification
… Temperature change has the strongest effect on ash slag (lesser viscosity and thickness) while ash composition has a very small effect (greater viscosity and thickness).

Sustainable cementitious materials for building and sorption applications
… precursor aluminosilicate materials (e.g., fly ash composition) on the long-term performance of the derived cementitious material. Therefore, the overall objective of this research work is to investigate the aforementioned two sustainable alternative cementitious materials with a view to …

A Study of the Bulk Electrical Resistivity Characteristics of Fly Ash from Lignite and Other Western Coals
<p>Fly ash produced from burning fossil fuels presents an air pollution problem when it is discharged into the atmosphere. Fly ash can be removed from gases using electrostatic precipitation. Efficiency of precipitation depends to a large extent on the bulk electrical resistivity of the fly ash …

Igneous life cycles: geochemistry of magma from mantle to surface and back again
… volcanism generates a wide diversity of magma compositions, but the tempos of compositional variation are unclear. Here, we investigate a 7-million year record of volcanic ash layers in the Cretaceous Eagle Ford Group to investigate temporal changes in ash composition on <100 kyr timescales. We …

Syngas ash deposition for a three row film cooled leading edge turbine vane
… on the gas clean up procedures used, coal composition and operating conditions. These byproducts when combined with high temperatures and high gas stream velocities can cause Deposition, Erosion, and Corrosion (DEC) of turbine components downstream of the combustor section. The objective of …
