Device for heating liquids

The invention relates to a device for heating or warming liquids and in particular. in particular on a boiler for the storage and supply of hot water, which uses a burner, which a pressure jet flame generated z. B, from the top of a boiler is directed downwards into a vertical combustion chamber, with an enlarged intermediate chamber is provided, which is in-the boiler drum near the boiler bottom is located; the intermediate chamber communicates with the vertical combustion chamber and with exhaust gas ducts in

the drum and has a diameter larger than the diameter of the combustion chamber and the gas ducts, so that the combination of these parts ensures a damping effect on the combustion noise.

According to the invention a device for heating of liquids provided, which has the following features: A container for the liquid to be heated, one inside Combustion chamber housed in the container, a pressure jet burner unit, which is attached to a wall of the container is arranged and directs its flames into the combustion chamber, an enlarged intermediate chamber, which is a larger Has diameter than the combustion chamber and receives one end of the combustion chamber, and turns at least one exhaust duct, which is located inside the container and has a diameter which is smaller than that of the enlarged intermediate chamber is, wherein the exhaust channel at one end with the intermediate chamber and at the other end with the atmosphere in communication stands.

The invention is explained in more detail below with reference to schematic drawings.

The boiler or the device for heating liquids according to the invention consists of a cylindrical one Liquid container or a boiler drum 1 with a side plate 2, a top plate 3 and a bottom plate M, as well as from a heat exchange unit, which is located within the drum 1 is located and is generally denoted by 5. The heat exchange unit 5 consists of an enlarged intermediate chamber 6, which is located at a close distance from the bottom plate 4 and by a flat plate-shaped plate element 7 and a cover plate 8 is limited and is provided at its bottom with a cleaning opening 9 which extends through the The base plate extends to the outside of the boiler drum 1; there is provided a vertical combustion chamber 10 which is cylindrical Has shape and extends through the head plate 3 down and at its lower end in the enlarged Intermediate chamber 6 opens, which has a horizontal cross-sectional area larger than that of the combustion chamber 10, the combustion chamber 10 having a pressure jet burner unit 11 attached to the head portion of this combustion chamber 10 is arranged and directs its flame downwards into this chamber 10; furthermore there is a plurality of exhaust ducts 12 cylindrical shape is provided, each having a cross-sectional area have, which is smaller than that of the enlarged intermediate chamber 6 and which at one end in this Chamber 6 and on the other linden tree through the top plate 3 open to the atmosphere. A liquid goes through the top plate 3

keitszufuhreinlaß 13 and a hot liquid outlet 11, the with the space inside the drum 1 at diametrically opposite one another. Make the head plate 3 in connection stand.

The plate-like plate element 7 can have any shape (it can be cylindrical or polygonal); it however, it is a plate element with a circular horizontal cross-section favorable because of toughness and strength. The arrangement of a space between the bottom surface of this plate-like plate element 7 and the inner surface of the bottom plate 1 results in an increased heating efficiency than with an arrangement that does not have such a space.

The exhaust gases first travel down through the combustion chamber 10 and then across the space in the enlarged Intermediate chamber 6 and then the gas channels 12 to the atmosphere to the outside. The combustion gases from the combustion chamber 10 suddenly introduced into the enlarged intermediate chamber, which has a considerably larger diameter or has a significantly larger horizontal cross-sectional area than the combustion chamber, the gases suddenly become considerably larger larger volume expanded or relaxed. Are then these gases suddenly from the intermediate chamber 6 in the out narrower gas channels 12, the volume of the gases is suddenly reduced considerably. The enlarged intermediate chamber 6 and the gas ducts 12 therefore act in exactly the same way as the known exhaust silencers for internal combustion engines

of motor vehicles. The noises when gas and flame flow into the boiler drum 1 according to the invention gradually and progressively decreased during the hiking path of the exhaust gases, initially with the sudden entry into the intermediate chamber 6, which is larger in diameter, from the combustion chamber 10 smaller diameter and then when entering the relatively narrow gas channels. the larger in diameter Intermediate chamber 6. Such a noise damping arrangement cannot be found in any known boiler. The change in Cross-sectional area of the channels of the exhaust leads to a significant Noise dampening effect in the boiler, in addition to the noise dampening effect caused by the vertical arranged combustion chamber is already reached in itself.

The invention has been explained using an example in which the combustion chamber and the burner unit of the Head side of the boiler drum are directed downwards. Of course the invention can also be applied to a boiler of the type that has a horizontally arranged Has burner unit, as well as a boiler, which has an upwardly directed burner unit; this is readily apparent to a person skilled in the art.

The enlarged intermediate chamber can be through different Designs are modified, so is z. B. a cylindrical or rectangular box-like shape possible, which depends on the type of arrangement of the combustion chamber, the position and position of the enlarged intermediate chamber accordingly would be to choose.

. The enlarged intermediate chamber can as long as any Have a shape as having a diameter or dimension considerably larger than that of the combustion chamber and the gas passages, so that the damping effect is also achieved.
