Definitions
- the present invention relates to a heating element for heating gases to high temperatures, comprising at least one tube 1 designed for the passage of hot gas or gas and an electric heating wire in the tube, which is used to transfer heat to the heating wire passing gas is designed.
- the present invention also relates to a process heater having a housing with a gas supply and a gas outlet, a heating space between gas supply and gas outlet for receiving a heating element and electrical connections for at least one heating element,
- Corresponding heating elements have long been known. They consist, as already mentioned, of at least one pipe to be flowed through by gas, which is open on both sides for the purpose of flowing through, wherein in the pipe a heating wire is arranged, at which the gas flows past and through the direct contact with the heating wire heated.
- heating wires helically wound, fine wires whose cross-section is much smaller than the pipe cross-section and are flowed through by electricity and heat thereby.
- the electrical energy converted into heat by the heating wire naturally depends on the available electrical voltage and the resistance of corresponding heating wires, whereby the length of a coiled wire can be adapted to achieve desired resistance values or several corresponding heating wires can be connected in parallel or in series.
- the heat energy transferred to the gas flowing along the heating wire depends on the maximum temperature reached by the heating wire, on the flow velocity and on the surface available for heat exchange as well as on the exact flow conditions in the heating element.
- the maximum gas temperatures which can be reached regularly in continuous operation with such process heaters in practice, are in the order of 700 ° C.
- heating wire typically contains aluminum in small amounts, contact with oxygen initially results in the formation of a protective aluminum oxide layer around the wire.
- a large surface-to-volume ratio of the heating wires is considered advantageous for an effective transmission of the heat energy generated in the heating wire on the gas flowing past, so far the short life of such heating elements is accepted when gas temperatures in the range of 900 ° C or above.
- Process heaters and heating elements which generate gas temperatures of 900 ° C or even above, but for the aforementioned reasons regularly have only a service life of a few hours.
- the object of the present invention is to provide a process heater and a corresponding heating element which permit the generation of gas temperatures of up to 1000 ° C. or even higher, so that extremely large amounts of energy can be transferred to the gas and nevertheless remain relatively long Lifetime, which is at least 10 times the life of conventional heating coils in the generation of gas temperatures up to 1000 ° C usually.
- This object is achieved in that the heating wire is formed as extending along the tube axis heating rod whose maximum clear distance to the inner wall of the tube over at least 80% of the circumference and / or at least 80% of the overlap length of the tube and heater a value of 10 mm does not exceed.
- the heating wire is not a coiled wire whose material cross-section is substantially smaller than that of the tube, but rather a rod, for which in turn one can define a corresponding longitudinal axis which extends substantially along or parallel to the axis of the tube and while the tube fills so far that between the heating rod and tube wall remains only a relatively small, clear distance which is at most 10 mm and preferably still significantly less, even if he punctually, ie in areas less than 20% of the overlap length of pipe and Heater or make up less than 20% of the circumference of the heater can be greater.
- the term "heating wire” is therefore used in the present description as a generic term for both relatively thin coiled wires and for heating rods according to the present invention, wherein the different thickness is not the primary distinguishing criterion.
- the maximum clear distance between the heating element and the tube is between 1 and 2 mm in many practical cases, slightly above or below it down to minimum values of 0.02 mm.
- the maximum diameter of the heating element is rarely more than 10 mm, because even larger diameters, the efficiency of energy transfer significantly decreases because of a relatively large volume / surface ratio of the heating element, which can only be partially compensated by a larger Rohrund Walkerstabus. In principle, however, the use of heating elements with larger diameters is possible, although not preferred.
- a diameter range for heating rods apparently favorable in practice for the purposes of the present invention is between 0.5 mm and 5 mm.
- pipe is to be interpreted broadly in the sense of the present invention and ultimately only defines a cavity with an inlet and an outlet opening, which allow a flow of gas to be heated, not even the cross-section being constant over the length of the pipe. even if this is of course preferred in order to produce a largely constant gap, in particular a constant annular gap, between the heating rod and the tube wall by simple means
- the annular gap can be defined by elevations which are distributed over the circumference on the heating rod surface or on the inner surface of the tube are arranged to be interrupted in order to allow a centering of the heating element and to ensure a homogeneous heat transfer.
- through-holes in a solid block are also considered to be tubes, such a block having a multiplicity of parallel bores.
- the heating rods according to the present invention are relatively thick compared to the coiled wires in corresponding tubes of conventional heaters, they can heat internally. transfer and distribute what helps prevent local overheating, and they have for this reason at high thermal stress or high heating rod temperatures beyond 1000 ° C a significantly longer life and durability or allow only the heating of gases to over 1000 ° C with metallic electric heating elements.
- An alternative condition instead of the maximum clear distance between the heating element and the tube can be expressed by a minimum ratio of the cross-sectional area of the heating element to the free inner cross section of the tube.
- the heater should, at least as far as it extends within the pipe, have a cross-sectional area which is at least 30% and more preferably at least 50% of the free pipe cross-section.
- this aspect ratio was about 80%, wherein the maximum clear distance was 0.2 to 0.5 mm and a correspondingly uniform annular gap between the heating element and the tube wall about 0.1 to 0.25 mm amounted to.
- the preferred proportions between the cross section of the heating element and the inner cross section of the tube are expediently in the range of 0.2 to about 0.95.
- a cross-sectional ratio of 0.2 results, for example, in a very thin heating rod diameter of 0.2 mm and a tube diameter of 0.45 mm ,.
- a cross-sectional ratio of 0.9 is obtained, for example, with a heater rod diameter of about 4.75 mm in a tube with 5 mm inner diameter, wherein it does not matter in terms of the cross-sectional ratios on the unit or on the absolute dimensions, as long as the Schustab screenmesser within the above and below ranges.
- a preferred range of cross-sectional ratios is between 0.3 and 0.8, corresponding to a diameter ratio of between about 0.5 and 0.9 with absolute diameters of the heating rods between 0.5 and 5 mm.
- the annular gap along the circumference of the heating element also does not necessarily have to have a constant width, but can vary between 0 (contact) and the maximum value (in the case of circular cross sections, ie twice the uniform gap width.
- the absolute pipe diameter and Wienstab preparedr can vary widely, for example between an inner diameter of the tube from 1 mm to 20 mm or more, z. B. 60 mm, again depending on the other dimensions, such as the length of tube and heater, the desired width of the annular gap, the gas flow rate and the electrical resistance of the heater and the available voltage.
- the heating rod has a correspondingly smaller diameter for small pipe diameters, and in an extreme case also 0.5 mm or less, e.g. May be 0.2 mm. He is so compared to conventional helical wires or Schufilraitn but still significantly thicker and especially not coiled, but extends parallel to the tube axis and along the tube axis.
- heating element of a heating element according to the present invention is usually also thicker than the heating wires in conventional heating elements with the same tube cross-section and a heating element in the overall comparable heating element according to the prior art.
- the heating element is arranged as accurately as possible in the center of the tube, wherein the outer cross section of the heating element substantially coincides with the shape of the inner cross section of the tube, resulting in the result that the annular gap between the heating element and inner wall of the tube has a substantially constant width Has.
- the inner surface of the tube and / or the outer surface of the heating element could also be structured, i. For example, have a running in the longitudinal direction of the rod and the tube rib or groove structure, which may also have a small helix angle. For a given annular gap width, such superficial structures may extend the laminar flow region to larger gas flow rates.
- the concrete width of the annular gap always represents a compromise between maximum heat energy transfer and pressure loss at the desired gas flow rate. That is, the narrower the annular gap, the more effective is the heat transfer from the heating element to the gas flowing between the heating element and the tube, with a narrow gap but also limits the gas flow and / or requires a large pressure difference between inlet and outlet. In addition, the reasonable width of the annular gap but also depends on the length of the tube and also from the converted in the heating element electric heating power.
- the average width of the annular gap is about 0.1 mm, in another example, 0.2 mm but it is not always possible to really concentrically arrange the heating element in a tube, so that the annular gap width at least at some axial positions in the circumferential direction can vary between zero and twice the average annular gap width.
- spacers are therefore provided at some positions along the circumference and / or over the length, which center the heating element in the tube.
- the spacers may be integrally formed with the heating element or the tube and are in particular designed so that they impede the gas flow between the heating element and the pipe as little as possible.
- the spacers are preferably made of heat-resistant ceramic and are ideally realized via the tube geometry.
- heating rod and tube are arranged coaxially with each other, d. H. their axes collapse.
- the heating element and the tube but by no means have a circular cross section, they could for example also have the cross section of a preferably equilateral polygon and it could, for example, a pipe with hexagonal or octagonal cross-section or outer contour, which receives a cylindrical heating element.
- a square or hexagonal outer contour of the tubes allows a very compact arrangement of the tube bundle and a resulting minimal bypass flow between the tubes.
- a plurality of parallel tubes are combined to form a tube package and the heating element, more precisely the heating rods of the individual tubes of the tube package have the shape of a meandering passed through the heating wire, which is inserted at the end of a tube and from the outlet side
