Untersuchungen zur Alkalireinigung von Heißgasen für Anlagen mit Kohlenstaub-Druckfeuerung
… of CO2-Emission and protection of resources. Alkali metals, released during combustion at temperatures above 1600 °C, can cause hot corrosion of gas turbine materials in contact with the hot flue gas. That's why a hot gas cleanup related to alkalis is indispensable. Silicate melts like coal …

Freisetzung und Einbindung von Schwermetallen bei der Hochtemperaturvergasung
… temperatures is widely less investigated than alkali or sulphur removal by sorption. The intention of this study was to determine the capability of available sulphur and alkali sorption materials for the removal of heavy metals. The examined heavy metals in this work were arsenic, cadmium, …

Einbindung von Alkalimetallen bei der Druckkohlensstaubfeuerung
… turbine. A mayor problem of the PPCC is the high alkali content of the hot flue gases. The alkalis released during coal combustion can react with gaseous sulphur to alkali sulphates. These compounds cause high temperature corrosion of the Ni-base alloys of the turbine bladings. For this reason, …
