Definitions

  • This invention relates to hot gas generators of the kind comprising in combination, a combustion chamber, a turbine which is driven by exhaust gases leaving the combustion chamber, a first compressor driven by said turbine for providing dilution air to the combustion chamber, and a second compressor for providing an air/fuel mixture to a burner disposed within the combustion chamber.
  • the object of this invention is to provide such an apparatus in a form in which the possibility of the generation of undesirable combustion products is minimised.
  • a portion of the exhaust gases leaving the turbine is admitted to the inlet of the second compressor thereby reducing the combustion temperature.
  • FIG. 1 is a sectional side elevation of one example of a hot gas generator to which the invention may be applied and FIG. 2 is a diagrammatic representation of the generator of FIG. 1 modified in accordance with the invention.
  • a body part 10 in which is mounted a rotary shaft 11.
  • a radial flow turbine rotor 12 At one end of the shaft is mounted a radial flow turbine rotor 12 which is accommodated within a turbine casing 13 having a tangential inlet 14 and an axially extending outlet 15.
  • the turbine casing is secured to the body part 10.
  • a pair of radial flow compressor rotors 16 and 17 disposed in compressor casings 18 and 19 respectively.
  • the compressor defined by the rotor 16 and casing is hereinafter called the first compressor whilst the compressor defined by the rotor 17 and the casing 19 is hereinafter called the second compressor.
  • the casings 18 and 19 have tangential outlets 20 and 21 respectively and inlets 22 and 23.
  • a combustion chamber indicated at 24 includes an outer casing 25 which is of generally cylindrical form and having a throat portion 26.
  • the downstream end of the combustion chamber is secured ted States Patent 0 to the inlet 14 of the turbine and upstream of the throat portion is an annular carrier 27 which serves to support the downstream end of a flame tube 28.
  • the upstream end of the flame tube is supported by a burner assembly 29 secured to the upstream end of the outer casing.
  • Surrounding the flame tube is an annular space to which dilution air is fed by the second compressor through a pipe 29.
  • Formed in the flame tube are holes 30 through which the dilution air flows into the flame tube.
  • the burner assembly 29 is in communication with the outlet 20 of the first compressor by way of a pipe 31.
  • an ignition plug 32 which extends into the flame tube downstream of the burner assembly 29 so as to ignite the air/fuel mixture entering the combustion chamber.
  • a carburettor indicated at 33 in FIG. 2 is provided.
  • the carburettor is supplied with fuel from a source 34 and when liquid fuel is employed a conventional fuel carburettor having a venturi may be provided in order to draw the fuel into the air stream.
  • a gaseous fuel such for instance as town gas, natural gas or vapourised petroleum gas
  • the gas will be supplied under a slight pressure to the nozzle of the carburettor so that the latter is little more than a mixing device for the air and gas.
  • the heated gases leaving the combustion chamber drive the turbine rotor prior to being discharged through ducting or the like.
  • the turbine rotor in turn drives the compressor rotors which supply the air/fuel mixture and the dilution air to the combustion chamber.
  • the dilution air acts to reduce the temperature of the gases entering the turbine so that the safe working temperature thereof is not exceeded.
  • the exhaust gases leaving the outlet of the turbine are admitted to the inlet 22 of the second compressor.
  • the exhaust gases leaving the turbine have a lower oxygen content than pure air and therefore the combustion temperature will be lowered.
  • the exhaust gases are conveyed along a duct 35 to a point downstream of the carburettor 33 and for controlling the quantity of gas flowing a valve 36 is provided. In this manner the combustion temperature can be controlled.
  • a hot gas generator comprising in combination, a combustion chamber, a burner disposed in the combustion chamber, a turbine which is driven by exhaust gases leaving the combustion chamber, a first compressor driven by said turbine for providing dilution air to the combustion chamber to control the temperature of the exhaust gases entering the turbine, a second compressor driven by the turbine for delivering an air/fuel mixture to the burner, a duct through which the exhaust gases can flow between the outlet of the turbine and the inlet of the second compressor and valve means for controlling the flow of gas through said duct, the exhaust gas when mixed with the air/fuel mixture supplied to the burner 4 acting to reduce the combustion temperature. of the.air/..
