Abstract
Μέθοδος καύσεως στερού καυσίμου το οποίον έχει αλκαλικές συνθέσεις χαμηλού σημείου τήξεως, όπως εναι τα αλκαλικά μεταλλικά άλατα, ιδιαιτέρως ο λιγνίτης και αλατούχος λιγνίτης. Το καύσιμο εισάγεται εντός του θαλάμου αντιδράσεως ενός αντιδραστήρα κυκλοφορούντος ρευστοποιημένου στρώματος, και αναμιγνύεται πριν από την εισαγωγή στον θάλαμο αντιδράσεως με ένα υλικόν αντιδραστηρίου ικανόν ν' αντιδρά μετά των αλκαλικών συθέσεων χαμηλού σημείου τήξεως του καυσίμου για παραγωγή αλκαλικών μεταλλικών ενώσεων υψηλού σημείου τήξεως κατά τη διάρκεια της καύσεως. Η θερμοκρασία στον θάλαμο αντιδράσεως κρατείται κάτω του σημείου τήξεως των σχηματιζομένων αλκαλικών μεταλλικών ενώσεων. Το υλικόν αντιδραστηρίου περιλαμβάνει οξείδιο πυριτίου ή μέταλλον οξείδιο, ή υδροξείδιο, της ομάδας η οποία συνίσταται από αλουμίνιο, ασβέστιο, μαγνήσιο, σίδηρος, τιτάνιον, και μίγματα εκ δύο ή περισσοτέρων εξ αυτών. Η καολίνη είναι ιδιαιτέρως αποτελεσματική, ειδικώς όταν ο μαζικός λόγος του Al/(Na και Κ) είναι τουλάχιστον 1,0. ωA method of burning solid fuel which has alkaline compositions with a low melting point, such as alkali metal salts, particularly lignite and saline lignite. The fuel is introduced into the reaction chamber of a fluidized bed reactor, and is mixed prior to introduction into the reaction chamber with a reactant material capable of reacting with the low melting point alkaline compositions of the fuel to produce high melting point alkali metal compounds during of burning. The temperature in the reaction chamber is kept below the melting point of the alkali metal compounds formed. The reagent material includes silicon oxide or a metal oxide, or hydroxide, of the group consisting of aluminum, calcium, magnesium, iron, titanium, and mixtures of two or more thereof. Kaolin is particularly effective, especially when the mass ratio of Al/(Na and K) is at least 1.0. oh
