Abstract

The exchanger has spirally, upwardly extending rectangular channels provided in a wall of the exchanger, and conically tapered upto an upper end for obtaining natural circulation. Circulation pumps are connected between the channels. Inlet and outlet connections are provided with blocking valves. A pressure relief valve is provided in the exchanger. A bypass line bypasses fluid i.e. water, to extent that the fluid is not heated. An additional holder serves for wall fastening. The exchanger is connected to a buffer tank for feeding heat recovered from standard heating or domestic water heating.

Description

Technische Beschreibung:Technical description:

bei dieser Erfindung wird anstelle des Rauchabgasrohres ein Konvektionswärmetauscher eingesetzt. Der der Konvektionswärmetauscher kann in baugleicher Form ausgeführt werden wie das Standard Rauchabgasrohr. Aufgrund dieser gewählten Bauform können viele kleinere bis mittlere Öfen mit dieser technischen Erfindungen nachgerüstet werden insofern ein Pufferspeicher vorhanden ist. Eine weitere Lösung besteht darin den Wärmetauscher nur als Teilstück des Abgasrohres auszuführen und mit dem restlichen Abgasrohr zu verbinden. Der Wärmetauscher besteht aus einem ca. 2–3 cm dickwandigen Guss- oder Stahlrohr oder anderen gut leitenden Metallen, in dessen Wand sich ein Kanal mit eckigem Querschnitt spiralförmig nach oben windet. Der Kanal der das flüssige Wärmeträgermedium aufnimmt läuft zum oberen Ende konisch zu. Dies ermöglicht eine natürliche Flussgeschwindigkeit wobei es sinnvoll ist konstruktiv auch eine 70 Umwältspumpe vorzusehen um größere Wassermengen erwärmen zu können. Am unteren Ende des Wärmetauscher befindet sich ein Einlassstutzen mit Absperrventil und am oberen Ende ein Auslassstutzen ebenfalls mit Absperrventil. Zur Sicherheit wird bei diesem Wärmetauscher ein Überdruckventil eingebaut. Der Wärmetauscher erhält eine Beipassleitung die für die Umleitung des Fluidums dient insofern das Fluid nicht weiter erwärmt werden soll. Um die Standsicherheit zu gewährleisten ist der Wärmetauscher mit einer zusätzlichen Halterung, die der Wandbefestigung dient, ausgestattet. Der Wärmetauscher sollte jährlich einer gründlichen Reinigung unterzogen werden um eine gute Wärmeleitfähigkeit zu gewährleisten. Daher sollten die Zu- und Ableitungen ebenfalls mit Absperrventilen versehen sein.In this invention, a convection heat exchanger is used instead of the flue gas tube. The convection heat exchanger can be designed in the same design as the standard smoke exhaust pipe. Due to this selected design many small to medium size furnaces can be retrofitted with these technical inventions insofar as a buffer memory is present. Another solution is to perform the heat exchanger only as a part of the exhaust pipe and connect to the rest of the exhaust pipe. The heat exchanger consists of a 2-3 cm thick-walled cast iron or steel pipe or other highly conductive metals, in the wall of which a channel with an angular cross-section spirals upwards. The channel which receives the liquid heat transfer medium runs conically towards the upper end. This allows a natural flow rate where it makes sense constructively provide a 70 circulating pump to heat larger amounts of water can. At the lower end of the heat exchanger there is an inlet with shut-off valve and at the upper end an outlet with shut-off valve. For safety, a pressure relief valve is installed in this heat exchanger. The heat exchanger receives a bypass line which serves for the diversion of the fluid insofar as the fluid should not be further heated. To ensure stability, the heat exchanger is equipped with an additional bracket, which serves as wall mounting. The heat exchanger should be thoroughly cleaned annually to ensure good thermal conductivity. Therefore, the supply and discharge lines should also be provided with shut-off valves.
