Abstract

To utilise the condensation heat in the heat generation, the hot waste gases are according to the invention mixed with water by means of a jet nozzle. The water draws the hot gases out of the combustion chamber and cools them to below their condensation point. The water/gas mixture can be supplied to a heat exchanger and subsequently be separated from the harmful components in a filter.

Description

Die Erfindung betrifft die Wärmeerzeugung mittels einer unmittelbar hinter der Brennkammer installierten Jet-Düse, die, durch Wasser betrieben, die heißen Abgase aus der Brennkammer heraussaugt. Es entsteht ein Gas-Wassergemisch, das unter dem Kondensationspunkt der Abgase liegt. Dieses Gemisch kann nunmehr einem Wärmetauscher zugeführt werden. Es ist bekannt, daß, um einen besseren Wirkungsgrad zu erzielen, die heißen Brenngase unter ihren Kondensationspunkt abgekühlt werden können, um die Kondensationswärme auszunützen (Brennwertkessel). Dies geschieht bei allen herkömmlichen Konstruktionen durch zusätzliche Abkühlung in einem Wärmetauscher. Vermehrter Aufwand und damit höhere Kosten dämpfen jedoch deren Wirtschaftlichkeit.The invention relates to heat generation by means of a jet nozzle installed directly behind the combustion chamber, which, operated by water, are the hot exhaust gases from the Sucks out the combustion chamber. A gas-water mixture is created which is below the condensation point of the exhaust gases. This Mixture can now be fed to a heat exchanger. It is known to improve efficiency achieve the hot fuel gases below their condensation point can be cooled to take advantage of the heat of condensation (Condensing boiler). This happens to everyone conventional constructions by additional cooling in a heat exchanger. Increased effort and thus higher However, costs dampen their profitability.

Der Erfindung liegt die Aufgabe zugrunde, in einer einfachen, kompakten und billigen Konstruktion die Kondensationswärme auszunützen.The invention has for its object in a simple, compact and cheap construction the heat of condensation to take advantage of.

Die Kondensationswärme wird sofort durch Mischung mit Wasser in der Jet-Düse gewonnen. Das Volumen der Abgase verringert sich durch deren schlagartige Abkühlung. Der nachgeschaltete Wärmetauscher kann sehr klein, und die heißen Anteile des Wärmetauschers sehr niedrig gehalten werden. Die Abstrahlungsverluste reduzieren sich drastisch und die niedrigeren Temperaturen erlauben einfachere Konstruktionen. Die schädlichen Bestandteile der Abgase können vorteilhaft aus dem Wasser-Gasgemisch herausgefiltert werden. Das Wasser kann nach Trennung von den Gasen wieder in einem geschlossenen Kreislauf der Jet-Düse zugeführt werden.The heat of condensation is immediately mixed with Water won in the jet nozzle. The volume of the exhaust gases is reduced by their sudden cooling. The downstream heat exchanger can be very small, and that hot parts of the heat exchanger are kept very low will. The radiation losses are drastically reduced and the lower temperatures allow easier ones Constructions. The harmful components of the exhaust gases can advantageously be filtered out of the water-gas mixture will. The water can be separated from the gases again in a closed circuit of the jet nozzle are fed.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.An embodiment is shown in the drawing.
