Definitions

  • the present invention relates to a boiler for recovering hot gases, in particular at the outlet of a gas turbine.
  • a hot gas recovery boiler comprising a gas inlet duct of generally horizontal direction, a gas deflection duct connected to the preceding duct and leading to a substantially vertical direction enclosure and containing a set of substantially horizontal and superimposed heat exchange stages and a smoke evacuation duct at the upper end of the enclosure.
  • the temperatures of the gases leaving a gas turbine are very high and can currently reach 650 ° C.
  • the inlet and deflection pipes must therefore be designed to withstand these temperatures. They cannot be made entirely of stainless steel, given the problems of expansion which would result therefrom given their large size. They therefore generally consist of a so-called warm sheet made of a steel sheet, a layer of thermal insulator and stainless steel plates arranged in the form of scales. Thus the steel sheet, in particular E24 steel, is maintained at a temperature of around 320 ° C. In addition to its relatively complex constitution, such a sheet poses problems of relative fragility.
  • the present invention proposes to solve these problems and to do this, at least one heat exchanger is disposed near the outlet of said inlet conduit so as to reduce the temperature of the gases at the outlet of this exchanger, said heat exchanger being inclined and its exit surface facing the entrance to the enclosure.
  • the conduit where the temperature is very high, for example around 650 ° C., is limited to the inlet conduit of smaller size.
  • the deflection conduit reigns a lower temperature, for example 560 ° C, allowing to release in this conduit insulation constraints and in particular no longer requiring a sheet called warm.
  • the distribution of the gas flow is also improved downstream of the exchanger before the gases enter the enclosure of the boiler, thanks to the inclination of the exchanger and the arrangement made by its anti-vibration baffles.
  • the exchanger thus constitutes a system for homogenizing the gas flow.
  • This inclined arrangement also makes it possible to reduce the height of the boiler.
  • the deflection pipe can be made of steel, preferably steel with 2.25% chromium.
  • the inlet duct can be made of stainless steel.
  • outlet surface of the inlet duct and the inlet surface of the deflection duct are inclined, turned towards the inlet of the enclosure and connected by an expansion joint.
  • the exchanger is arranged just upstream of the expansion joint.
  • the exchanger constitutes at least partially a lower heat exchange stage of the boiler.
  • Figure 1 is a vertical sectional view of a boiler according to the invention.
  • Figure 2 shows schematically the water-steam circuit of the heat exchange stages in the case of a recovery boiler with three pressures and overheating and of a combined gas turbine and steam turbine cycle.
  • the recovery boiler shown is disposed at the outlet of a gas turbine and conventionally comprises an inlet duct 1 for gases of generally horizontal direction, a deflection duct 2 for the gases connected to the preceding duct 1 and leading to a enclosure 3 of substantially vertical direction and containing a set of substantially horizontal and superimposed heat exchange stages and a smoke evacuation duct 4 at the upper end of enclosure 3.
  • At least one heat exchanger 5 is disposed near the outlet of said inlet duct 1. It is inclined, its outlet surface 6 being turned towards the inlet 7 of the pregnant 3.
  • the deflection pipe 2 is made of steel, preferably steel with 2.25% chromium and the inlet pipe 1 is made of stainless steel.
  • the outlet surface of the inlet duct 1 and the inlet surface of the deflection duct 2 are inclined, turned towards the inlet of the enclosure 3 and connected by an expansion joint 8 and the exchanger 6 is arranged just upstream of the expansion joint 8.
  • the exchanger 6 constitutes at least partially a lower heat exchange stage of the boiler.
  • the exchanger 6 is double and consists of the HT 28 superheater and the HT 37 superheater.
  • this HT 28 superheater and this HT 37 superheater are arranged with the other heat exchange stages in the enclosure 3 of the boiler.
  • the invention consists in transfer at least one of these elements at the outlet of the inlet duct 1.
