Abstract

Ash fusion temperature determines suitability of coal for the entrained flow gasification/combustion process. For this, an Indonesian “Sehwa” coal sample and its acidic ash and slag constituents have been comprehensibly characterized via X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS) and inductively coupled plasma optical emission spectrometry (ICP-OES) methods. For assessment of environmental impact, leachate solution was also prepared from the discharged slag for ICP-OES analysis. The experimental data were comprehensively explained by ash fusion temperature and FactSage® thermochemical software and databases for understanding the thermodynamic fluidity properties of the coal ashes. More specifically, coal slagging behavior inside of the coal gasifier/combustor necessitated optimization of operational condition for subsequent mild slagging. The currently used coal gasification operation temperature range caused insufficient fraction of liquid available at 1200 to 1300 °C (19.7–20.1 bar). The metallic element-wise compositional analysis result via ICP-OES performed on the leachate solution therefrom excluded possibility of secondary environmental pollution from the discharged slag. This contribution continues the already published studies of the physicochemical characterization of slag waste from coal gasification syngas plants supplemented with FactSage® thermodynamic modeling results of coal gasification slag (SiO2–Al2O3–TiO2–Fe2O3–CaO–MgO–Na2O–K2O–P2O5–MnO–SO3). Besides, essentially similar experimental procedure to that employed in the already published studies was used to compare ash transformation and slagging behavior of the acidic coal feedstock.

Kurzfassung

Die Aschefusionstemperatur bestimmt die Eignung von Kohle für den Prozess der Flugstromvergasung. Hierfür wurde eine indonesische Probe der Sehwa-Kohle verwendet und ihre sauren Asche- und Schlackeinhalte mittels Röntgenfluoureszenz, Röntgendiffraktometrie und Rasterelektronenmikroskopie mit energiedispersiver Spektroskopie sowie induktiv gekoppelten Verfahren der Emissionsspektroskopie charakterisiert. Zur Abschätzung der Umweltfolgen wurden außerdem für die ICP-OES-Analyse eine entsprechende Lösung hergestellt. Die experimentellen Daten werden anhand der Aschefusionstemperatur erklärt sowie anhand der thermodynamischen Software und Datenbasis FactSage®, um die thermodynamischen Flüssigkeitseigenschaften der Kohleaschen zu verstehen. Das Kohleschlacke-Verhalten innerhalb des Kohlevergasers bzw. der Brennkammer machte die Optimierung der Betriebsbedingungen für eine nachfolgende schwache Verschlackung notwendig. Die bisher angewandte Kohlevergasungstemperatur verursachte einen ungeeigneten Anteil an Flüssigkeit bei 1200 bis 1300 °C und 19,7 bis 20,1 bar. Die metallische elementweise Analyse der Zusammensetzung mittels ICP-OES an der Lösung schloss von daher die Möglichkeit einer sekundären Umweltverschmutzung durch die abgeführte Schlacke aus. Der vorliegende Beitrag setzt die bereits veröffentlichten Studien der physikochemischen Charakterisierung des Schlackeabfalls (SiO2–Al2O3–TiO2–Fe2O3–CaO–MgO–Na2O–K2O–P2O5–MnO–SO3) aus Kohlevergasungsanlagen fort, die mit den Ergebnissen der thermodynamischen Modellierung mittels FactSage® fort. Darüber hinaus wurde eine ähnliche experimentelle Prozedur wie in den bereits veröffentlichten Studien angewandt, um das Ascheumwandlungs- und Verschlackungsverhalten von sauren Kohlebeschickungen zu vergleichen.
