Definitions

  • the invention relates to a hot gas cooler according to the preamble of claim 1.
  • a hot gas cooler of this type is known from DE-OS 27 26 716 in the form of a high-temperature waste heat boiler.
  • the hot gas inlet channel is located at the lower end of the pressure vessel, so that the pressure compensation connection also branches off in the area of the lower end. If, for example, a leak is formed halfway up the cooling insert, hot gas passes through the cooling insert into the intermediate space because the gas pressure in the intermediate space decreases as a result of the leak. The gas entering the gap through the leak hits the wall of the pressure vessel and can locally overheat this wall, which could lead to a container explosion.
  • this object is achieved by the features of the characterizing part of claim 1.
  • the hot gas inlet duct and thus also the pressure compensation connection at the upper end of the interior, a higher pressure is established on the outside of the cooling insert because of the cooler gas column there than on its inside, and that over the entire height of the insert.
  • the pressure in the space is increased by connecting the pressure compensation connection in the area of the interior that is enlarged compared to the inlet duct. It is thereby achieved that if a leak occurs on the cooling insert, no hot gas can flow outward into the intermediate space through the leak, but at most cooled gas from the intermediate space enters the interior of the cooling insert.
  • Claim 3 teaches an appropriate use of existing elements as a cooler.
  • Claim 4 shows one of the invention's own possibilities for controlling the leakage: If a significant leakage occurs, the temperature of the gas rises in the area of the cooler outlet. This temperature is therefore a suitable measure of the size of a leak.
  • the features of claim 5 provide a way of comparing the measured temperature, so that leakage can also be inferred when starting and stopping as well as when changes in load.
  • a hot gas cooler 1 consists of a pressure vessel 2 with a cylindrical, double-walled insert 3, which is supplied below with cooling water via a radial supply nozzle 4.
  • the insert 3 forms a conical surface 6, to which a neck 8 connects, to which an outlet connection 9 for the cooling water is provided.
  • the neck 8 penetrates the pressure vessel 2 through a nozzle 10 with a flange 11.
  • the insert 3 has a flange 12 to which a funnel 16 with a neck 18 is tightly connected via a bellows 14.
  • This neck 18 also penetrates the pressure vessel 2 through a connector 20 with a flange 21.
  • the necks 8 and 18 are connected to the connectors 10 and 20 in a gas-tight manner.
  • a pressure compensation connection 30 is now provided in the area of the cone surface 6, which opens into the intermediate space 5 via a cooler 32 forming the cooling section.
  • the cooler 32 is connected in parallel to the flow path of the coolant in the insert 3 via a supply line 35 and a discharge line 36.
  • At the outlet of the cooler 32 there is a thermocouple 38 which is opposed by a thermocouple 39 installed in the space 5.
  • the thermocouples 38 and 39 are electrically connected in series in such a way that the signal directed to a display device 40 is proportional to the temperature difference at the measuring points of the two thermocouples 38 and 39.
  • a gas of, for example, 1,400 ° C. flows from the hot gas source (not shown) through the neck 8 into the interior 7 of the insert 3, in which it emits heat to the cooled insert 3 primarily by gas radiation.
  • the gas leaves the insert via the neck 18.
  • a pressure is set in the intermediate space 5, which is the same as the pressure on the conical surface 6, because when the system starts up, the gas in the insert increases with increasing pressure Pressure compensation connection 30 flows into the intermediate space 5 via the cooler 32.
  • the gas stagnating in the intermediate space 5 assumes a temperature which lies between the wall temperature of the insert 3 and that of the pressure vessel 2.
  • a leak now occurs for example on the bellows 14, a flow which depends on the pressure drop between the conical surface 6 and the bellows 14 forms in the intermediate space 5, the hot gas being cooled to a still permissible temperature depending on the amount of gas flowing through the leak .
  • the temperature drop in the cooler 32 is smaller with a large flow rate than with a small flow rate, it forms a measure of the size of the leak. This drop in temperature can be measured by determining the temperature at the inlet and outlet of the cooler 32 or by comparison with the undisturbed temperature, as shown in FIG gur 1 is shown.
  • an alarm device can be provided, which can also directly actuate a shutdown device if the input signal is correspondingly high.
  • the insert in FIG. 2 consists of a shirt 42 with an interior space 7 and a jacket 43, both of which are formed in their central section 44 as concentric circular cylinders with dense walls.
  • Shirt and coat consist of tubes 50 welded to one another via webs.
  • the tubes 50 of the shirt 42 are forked in a lower region 45, so that they no longer form a partition there, but instead allow the flue gas flowing through the shirt to pass into an annular space 25 between the shirt 42 and coat 43.
  • All tubes 50 are connected at their lower end to a distributor 52.
  • a part of the tubes 50 forming the jacket is bent outwards in a knee shape from the cylinder surface, so that the openings of the tubes 50 in the distributor 52 do not lie on the same jacket line, which would lead to a weakening of the distributor.
  • the webs each extend between adjacent straight tubes, so that the jacket 43 also forms a gas-tight wall in section 45.
  • the tubes 50 are bent toward the axis of the pressure vessel.
  • Part of the tubes of the shirt as well as the jacket form gas-tight shoulder surfaces 55 and 57 and gas-tight, adjoining necks 59 and 60.
  • Shirt 42 and coat 43 are hung on drawstrings 64 and 65 on two beam wreaths 68 and 69.
  • the drawstrings 64 are connected in the area between the two shoulders 55 and 57 to form a dense cylindrical wall.
  • the tubes of the neck 59 are an upper edge of the neck but they are deflected upwards at the lower end of the shirt and leave the annular space 25 via the line 78. Slag and soot particles fall largely into the funnel 16 due to the force of gravity, from which they flow with the water introduced there can be discharged.
  • the tubes 50 of the shirt 42 and the jacket 43 which are welded to one another form, for example, heating surfaces, preferably evaporator heating surfaces of a steam generator through which the flow is forced.
  • the tubes 50 can also be directly gas-tightly welded to one another instead of via webs.
