Definitions

  • the present invention relates to the field of balloon boilers used for example in the sector of power plants or process industries, and which are subject to frequent and rapid starts with high operating pressures.
  • the present invention relates to boilers of the type of heat recovery steam generator or HRSG (for heat recovery steam generator ).
  • the flask 1 is supplied with water by a feedwater line 4 ( feedwater line ) which contains a first valve "A”, called control valve 5 ( feed water control valve- FWCV).
  • feedwater line 4 feedwater line
  • control valve 5 feed water control valve- FWCV
  • the balloon 1 is connected to its loop "water downpipes - evaporator - water riser tubes”: the water flows from the balloon 1 to the evaporator by the downpipes 6 (downcomers), the water passes into the tubes of the evaporator 2 and is partially evaporated therein. This water / steam mixture is returned to the flask 1 by the riser tubes 7 ( risers ). The two water / vapor phases are separated in the flask by one or more appropriate equipment (methods), known to those skilled in the art.
  • the level of the body of water in the balloon is controlled by the control valve "A" 5.
  • the saturated steam above the body of water of the balloon escapes from the balloon by a leg 3 provided for this purpose and is directed to the steam network via the superheaters (if any), then feed the process or the steam turbine using the steam produced.
  • the volume of this ball must be sufficient for the ROT and swell effect considered.
  • the document US 2,702,026 A discloses a steam generating plant in which steam is generated from available heat to a plurality of separate heat sources, comprising: a plurality of independent natural circulation type individual boilers, each located at a different heat source and arranged to use the corresponding heat, each of the individual boilers having a vapor separation tank and tubes placed to extract heat from the heat source and connected with the balloon for the natural circulation of a boiler fluid through; boiler mounting means for all vapor balloons to be essentially at the same level; means for supplying feed water to each boiler at a rate governed by the heat taken from the respective boiler and independent of the feed water requirements of the other boilers; means for withdrawing steam from each boiler at a rate governed by the heat taken from the respective boiler and independent of the rate at which the steam is taken from the other boilers; pipelines interconnecting all vapor balloons above their water levels; and pipes connecting all the steam balloons below their water levels, the two types of pipes being completely independent of the circulation systems of the boilers and means for supplying the feedwater to
  • the document GB 241.961 A discloses a steam generator of the type comprising a heat radiation section and a heat convection section, wherein the tubes are arranged substantially vertically and parallel to one another.
  • the tubes in the radiation section are further apart than in the convection section.
  • the tube sections are connected to two upper water / steam separation tanks with steam outlet and also to an intermediate water tank.
  • the document US 2013/0145998 A1 relates to a system comprising an evaporator, a water tank in fluid communication with the evaporator, the water tank being located upstream of the evaporator, and a first vapor balloon in fluid communication with the evaporator, the first vapor balloon being located downstream of the evaporator, where the water reservoir operates to supply the evaporator feedwater while maintaining a predetermined water level in the first balloon of the evaporator; steam.
  • the present invention aims to provide a solution for balloon boilers subject to frequent and rapid starts with high operating pressures.
  • the invention aims to improve the fatigue resistance of the balloon, the issue being the life of this key equipment of the boiler.
  • the solution proposed in the context of the present invention is part of the multiple balloon solutions.
  • the principle is to spread over at least two reservoirs, or more than two reservoirs in a generalized version of the basic idea, the storage volume necessary to ensure on the one hand an imposed flow time (ROT) and on the other hand to accommodate the swell effect at startup or load transients.
  • ROT imposed flow time
  • the storage tank 8 In the new configuration containing the proposed improvement according to the invention shown on the Fig. 2 two volumes must be distinguished: the storage tank 8 and the boiler ball proper 1, performing the water / steam separation.
  • the tank or storage tank 8 is supplied with water by the food water pipe 4 which contains a first valve "A”, called the control valve 5.
  • This storage tank 8 is, during normal operation, completely filled and supplied with water.
  • the boiler balloon 1 through the overflow duct 9.
  • a second valve "B" called the actuatable valve 10 fitted to the backup supply duct 11 ( backup drum feeding line - BFL), is closed .
  • the boiler balloon is connected to its loop "descent tubes - evaporator - risers": the water flows from the tank 1 to the evaporator 2 through the water drops 6, the water then flows into the evaporator 2 tubes and is partially evaporated, this water / steam mixture being then returned to the flask 1 by the riser tubes 7.
  • the two water / steam phases are separated in the flask 1 by one or more suitable equipment (methods), known to those skilled in the art.
  • the level of the water in the tank 1 is controlled by the control valve "A" 5.
  • the saturated steam above the water level of the balloon 1 escapes from the balloon by the base 3 provided for this purpose and is directed to the steam network via the superheaters (if any), then feed the process or steam turbine using the steam produced.
  • the actuatable valve "B" opens partially or completely: the overflow duct 9 then makes vent office and the BFL 11 feeds the balloon 1.
  • the volume of the storage tank then contributes to ensure the required ROT.
  • Overflow duct 9 must lead to a sufficiently low position in the separator tank 1 to prevent any excessive rise of water in the upper part of the tank with overflow in the superheater or in the tubes of the steam circuit.
