Abstract

Die Erfindung betrifft ein Verfahren zur Verbrennung von Feststoffen in einem Verbrennungskessel (1), der zumindest einen Feuerraum (2) und eine Nachbrennkammer (4) umfaßt, wobei Luft mit Überschallgeschwindigkeit in eine Übergangszone I zwischen Feuerraum (2) und Nachbrennkammer (4) eingedüst wird sowie eine Vorrichtung zur Verbrennung von Feststoffen bestehend aus einem Verbrennungskessel (1) mit einem Feuerraum (2) und einer Nachbrennkammer (4), wobei am Austritt der Verbrennungsgase aus dem Feuerraum (2) Lavaldüsen (13 u. 14) angeordnet sind, über die von einem Verdichter (20) erzeugte und in einem Wärmetauscher (21) erhitzte Luft mit Überschallgeschwindigkeit in die Rauchgase eingedüst werden.

Figure 00000001
The invention relates to a method for the combustion of solids in a combustion boiler (1), which comprises at least one combustion chamber (2) and an afterburning chamber (4), air being injected at supersonic speed into a transition zone I between the combustion chamber (2) and the afterburning chamber (4) and a device for the combustion of solids consisting of a combustion boiler (1) with a combustion chamber (2) and an afterburning chamber (4), Laval nozzles (13 and 14) being arranged at the outlet of the combustion gases from the combustion chamber (2) the air generated by a compressor (20) and heated in a heat exchanger (21) is injected into the flue gases at supersonic speed.
