Verfahren zum Nutzbarmachen des Wärmeinhaltes von Abgasen mittels einer unmittelbar mit den Gasen in Berührung gebrachten Flüssigkeit.
Es ist bekannt, den Wärmeinhalt von Abgasen dadurch nutzbar zu machen, dass Wasser unmittelbar mit den Gasen in Berührung gebracht und diesen dadurch die Wärme entzogen wird. Die vom Wasser aufgenommene Wärme wird z. B. zur Abgabe an das Kesselspeisewasser verwendet. Die Ausführung des Verfahrens ist bekanntlich auf verschiedene Art möglich. Das Wasser kann in fein verteiltem Zustande in den Gasstrom eingeführt werden, wobei die Wasserteilchen und der Gasstrom sowohl in gleicher Richtung als auch im Gegenstrom, als auch in zwei verschiedenen Richtungen, Kreuzstrom, geführt werden können.
Gemäss der Erfindung werden statt Wasser Flüssigkeiten mit einem Siedepunkt, der höher ist als der des Wassers, z. B. Anilin und Pentachloräthan usw. verwendet.
Dies bietet die Möglichkeit, die Flüssigkeiten, welche den Gasen die Wärme entziehen, auf eine höhere Temperatur zu bringen als das zum gleichen Zweck verwendete Wasser, um damit auch eine höhere Vorwärmung des Speisewassers zu erzielen.
Bei Verwendung von Flüssigkeiten, die auch als Lösungsmittel für Teer, Öle und Stickstoffverbindungen dienen ; wie z. B. Pentachloräthan, wird auch gleichzeitig eine Reinigung der Feuergase erzielt bzw. die Möglichkeit geboten, die gelösten Stoffe rückzugewinnen.
PATENT-ANSPRÜCHE :
1. Verfahren zum Nutzbarmachen des Wärmeinhaltes von Abgasen mittels einer unmittelbar mit den Gasen in Berührung gebrachten Flüssigkeit, gekennzeichnet durch die Verwendung von Flüssigkeiten, deren Siedepunkt höher ist als der des Wassers.

Method for utilizing the heat content of exhaust gases by means of a liquid which is brought into direct contact with the gases.
It is known that the heat content of exhaust gases can be used by bringing water into direct contact with the gases and thereby extracting the heat from them. The heat absorbed by the water is z. B. used for delivery to the boiler feed water. As is known, the method can be carried out in various ways. The water can be introduced into the gas stream in a finely divided state, it being possible for the water particles and the gas stream to be conducted both in the same direction and in countercurrent, as well as in two different directions, crosscurrent.
According to the invention, liquids with a boiling point that is higher than that of water, eg. B. aniline and pentachloroethane, etc. used.
This offers the possibility of bringing the liquids, which remove the heat from the gases, to a higher temperature than the water used for the same purpose, in order to achieve a higher preheating of the feed water.
When using liquids that also serve as solvents for tar, oils and nitrogen compounds; such as B. pentachloroethane, a cleaning of the fire gases is achieved at the same time and the possibility is offered to recover the dissolved substances.
PATENT CLAIMS:
1. A method for utilizing the heat content of exhaust gases by means of a liquid brought into direct contact with the gases, characterized by the use of liquids whose boiling point is higher than that of water.
