Definitions

  • the invention relates to a method for starting a heat exchanger system provided in a hot gas line with an upstream starting heat exchanger for steam generation, is supplied via the feed medium and which first releases hot steam and finally water to the heat exchanger system when starting, so that the originally unpressurized empty and essentially heated heat exchanger system is continuous is brought from the initial state to its operating state, and a heat exchanger system for performing the method.
  • the starting heat exchanger is always connected to the hot gas, and thus, when the heat exchanger system is empty, has at least essentially the same hot gas temperature as its other heat exchanger.
  • It is designed as a heat accumulator with a high storage capacity as a system of concentric pipes, which can move against each other to compensate for the different thermal expansion when feeding water when the steam generator is started.
  • it is mentioned that it would not hurt if z. B. the inner tube of the system, where the water feed takes place, tears.
  • the starting heat exchanger according to this DE-A-3 741 882 has the major disadvantage that when starting the water flowing through it damages or destroys the protective layer in the entry zone because of the considerable temperature differences, and in particular iron is thereby introduced into the boiler system, thereby also endangering the heat exchanger system becomes.
  • the method according to the invention is accordingly primarily characterized in that, for starting up the heat exchanger system, the starting heat exchanger of the heat exchanger system, which is shielded from the hot gas flow by flaps, is charged with feed medium and then hot gas is applied to the gas side by opening the shield.
  • the heat exchanger system according to the invention for carrying out the method is characterized in that the starting heat exchanger is arranged in the hot gas line and can be shielded against the hot gas flow by means of flaps, or that the starting heat exchanger is in a secondary line which can be opened and closed by means of flaps, the passage cross section of the secondary line being substantially smaller than that Passage cross section of the hot gas line is arranged and the starting heat exchanger serves as an auxiliary steam generator for starting up the entire system from the cold state.
  • the starting heat exchanger has an additional water or. Steam supply is downstream; in this way, the start-up heat exchanger can be taken out of operation after starting.
  • the invention can be implemented on any heat exchanger system; preference is given to a closed system, where the condensate formed from the steam generated after work and cooling is returned as feed water; also on any steam generation system (such as forced circulation, natural circulation, forced circulation).
  • FIGS. 1 and 2 are continuous steam generators, the embodiments according to FIGS.
  • the system is fed in the direction of the arrow A 'with water (or steam) via a collector S1 into a starting heat exchanger 2, which is connected to the preheater 3 via collectors S2 and S3.
  • the starting heat exchanger 2 is arranged above the preheater 3 in the hot gas line 1 and by means of flaps 9 or the like in relation to the hot gas flow. shieldable. It can be seen that the system according to FIG. 1 is fundamentally fed via the collector S1, but a further feed point A wie can be provided as a further special feature between the collectors S2 and S3.
  • the cold starting heat exchanger shielded from the hot gas flow is first charged with steam or water and the shielding flaps are opened so that the hot gas comes into contact with the starting heat exchanger.
  • the flap position or the feed of the start heat exchanger 2, or both, are coordinated so that the start heat exchanger emits hot steam at the start of the start-up phase and hot water at the end of the start-up phase to the preheater 3, so that the system from the hot, empty in its Operating state cools down, where hot steam is just being formed in the superheater.
  • the shielding flaps 9 can remain open or closed; the start heat exchanger 2 then acts as a preheater; Accordingly, the heating surface of the ECO could be made smaller.
  • the starting heat exchanger 2 is provided in a branch line 10 of the hot gas line 1.
  • the branch line 10 can be closed by flaps 9.
  • a further feed point A ⁇ can be provided between the collectors S2 and S3, via which additional feed medium can be metered in, for example, when starting up, or in the operating state the only feed point is feed water; in the second case, the branch line 10 then usually remains closed and the starting heat exchanger is not supplied.
  • FIGS. 3 and 4 essentially correspond to the embodiments according to FIGS. 1 and 2; the only difference is their design as circulation systems with a boiler drum 8.
  • water comes from the preheater 3 via the collector S4 into the boiler drum 8, from where it goes to the collector 6, for which purpose a pump 7 is optionally provided, and from there into the evaporator 4 and via the collector S5 in the steam chamber of the boiler drum 8, from where it approaches the superheater 6 via the collector S7 and leaves it as service steam via the collector S8 in the direction of the arrow B 'to the consumer.
  • a bridging line 11 for controlled heating of the drum 8 can be provided between the steam space of the boiler drum 8 and the collector S2 connected in the flow direction to the starting heat exchanger 2.
  • This bypass line 11 can also be used to feed auxiliary steam into the auxiliary steam system of the system for starting up the system, so that no foreign medium is required for this.
  • each boiler system can be equipped with the starting heat exchanger arrangement according to the invention.
  • the water / steam cycle can also be provided in a known manner, i.e. that waste steam and / or waste water from the consumer returns to the heat exchanger system.
