Heizwert, Brennwert und Bildungsenthalpie im thermochemischen Standardzustand

Tabelle 55.1. Heizwert H_um und Brennwert H_om als negative Reaktionsenthalpie einer Verbrennungsreaktion sowie Reaktionsenthalpie einer inversen Bildungs-reaktion im thermochemischen Standardzustand (p₀ = 1 bar, T₀ = 298,15 K) der Gasphase. Zusätzlich angegeben ist die isobare Wärmekapazität c_p, die Bil- dungsenthalpie H_f und die Entropie S im Standardzustand. Die Atome der Verbindungen sind: C, H, N, O, S, Cl und F. Die angenommenen Produkte der Verbrennung sind: H₂O(g/fl), CO₂(g), SO₂(g), N₂(g), Cl₂(g) und F₂(g). Die beiden letzten Annahmen sind falsch, somit auch die Werte für den Heiz- und Brennwert. Am Ende der Tabelle stehen wichtige Stoffe im flüssigen Zustand. Werte hauptsächlich nach I. Barin: Thermochemical Data of Pure Substances, Part I and II, VCH (1989).

Dimethylether (DME) und Hexadecan (Cetan) im Diesel-Motor

Abb. 54.1. NOx-Emissionen von einem Diesel-Motor mit der Bohrung d = 75,5 mm, dem Hub s = 84,5 mm, dem Verdichtungsverhältnis ε = 17,8 und der Drehzahl n = 1200 U/min in Anlehnung an Yoon, S.H., Han, S.C. und Lee, C.S.: Effects of High EGR Rate on Dimethyl Ether (DME) Combustion and Pollutant Emission Characteristics in a Direct Injection Diesel Engine, Energies 2013, 6, 5157-5167. Die Lufteintritts- und Kühlwassertemperatur betragen t = 70°C. Der indizierte Mitteldruck bei der injizierten Brennstoffmasse m_B = 10,69 mg (Cetan) bzw. m_B = 16,4 mg (DME) liegt im Bereich p_i = 5,74 ... 6,62 bar entsprechend einer Last von etwa 53 %. Die Einspritzdauer ist Δφ = 15° Kurbelwinkel. Die äußere Abgasrückführung variiert von AGR = 0 % (Luftverhältnis λ = 2,33 entsprechend einem Sauerstoffgehalt von O₂ = 11,3 % im Abgas) über AGR = 30 % (λ = 1,66 entsprechend O₂ = 7,7 %) bis AGR = 50 % (λ = 1,14 entsprechend O₂ = 2,3 %). Das Luftverhältnis mit Cetan (AGR = 0) als Brennstoff ist λ = 2,15 mit O₂ = 10,8 %. Berechnung nach David G. Goodwin mit dem Programm Cantera. Die Reaktionskinetik von Cetan und DME stammt von der Creck Modeling Group (Ranzi, E. und Frassoldati, A.).

Abb. 54.2. Ruß-Emissionen für den Diesel-Motor nach Abb. 54.1. Die Ruß-Emissionen sind modelliert nach Hiroyasu, H. und Kadota, T.: Models for Combustion and Formation of Nitric Oxide and Soot in DI Diesel Engines, 1976, SAE Paper 760129. In diesem Modell wurde die Brennstoffmasse durch die auftretende Massenkonzentration von Acetylen ersetzt.

Zustandsgrößen für Oktan (n-Octan, n-Octane, C8H18)

Tabelle 53.1. Dampftafel für das Nassdampfgebiet von n-Octan (C₈H₁₈). Der Nullpunkt der spezifischen Enthalpie h liegt im gasförmigen Standardzustand (t₀ = 25 °C, p₀ = 100 kPa) des idealen Gases, die spezifische Entropie s ist die konventionelle (absolute) Entropie basierend auf der Standardentropie S⁰ = 467,352 J/(mol K) nach A. Burcat. Um die Werte nach NBP-Standard (h = 0 und s = 0 für siedende Flüssigkeit bei p = 1 atm) zu erhalten, muss zu den Enthalpiewerten Δh = 120,3441 kJ/kg addiert und von den Entropiewerten Δs = 3,861245 kJ/kg K subtrahiert werden. Berechnet mit der Zustandsgleichung von R. Span und W. Wagner: Equations of State for Technical Applications. II. Results for Nonpolar Fluids. Int. J. Thermophys., 24, 41-109, 2003. Die Zustandsgrößen für Toluol finden Sie hier. Berechnet mit CoolProp (Bell, I.H.).
