US4006591A — Jet reaction turbine with rotating combustor for …

Claim 1

Independent Claim 374 words

A reaction turbine for burning solid particulate fuels in slurry form delivered to the turbine from a fuel pressure regulator, and for discharging the resulting ash from the turbine to prevent accumulation therein, comprising: a. a frame having axially spaced journal supports and having a shaft journaled therein and supporting rotary air compressor means delivering air under pressure to an air intake housing adjacent one of the journal supports; b. a fuel burning rotor having an annular peripheral portion and having a first-end portion extending radially outwardly from the shaft to the peripheral portion, and having a second end portion fixed to the peripheral portion and having a central opening therethrough, the diameter of said peripheral portion being large as compared with the axial length of the rotor between said end portions; c. an annular series of jet orifices extending through said annular portion and spaced thereabout and each oriented substantially normal to a radius of the rotor intersecting the orifice; d. a chamber housing having one end fixed to said second end portion and communicating smoothly into said rotor thereat, and having its other end supported by journals at said one journal support and communicating with said air intake housing to receive compressed air; e. a fuel injector connected with said regulator and extending through said intake housing and axially through said other end of the chamber housing and having a nozzle facing into the housing operative to spray fuel thereinto; f. a combustion chamber sleeve in said chamber housing mounted concentrically therein in spaced relationship to the chamber housing and supported to rotate therewith, the combustion chamber sleeve being longer than its diameter and terminating at one end which is necked down to closely fit around the nozzle while leaving an airspace therebetween, and the other end of the sleeve being Venturi shaped and extending beyond said second end portion and flairing into the rotor; the intake air being divided so that a smaller portion of it passes into the sleeve through said airspace and a larger portion of it passes into the rotor by passing between the sleeve and the chamber housing; and g. a solid particle fuel in slurry form, and means to ignite the fuel sprayed from the nozzle.

Claim 2

Dependent Claim 374 words

A reaction turbine for burning solid particulate fuels in slurry form delivered to the turbine from a fuel pressure regulator, and for discharging the resulting ash from the turbine to prevent accumulation therein, comprising: a. a frame having axially spaced journal supports and having a shaft journaled therein and supporting rotary air compressor means delivering air under pressure to an air intake housing adjacent one of the journal supports; b. a fuel burning rotor having an annular peripheral portion and having a first-end portion extending radially outwardly from the shaft to the peripheral portion, and having a second end portion fixed to the peripheral portion and having a central opening therethrough, the diameter of said peripheral portion being large as compared with the axial length of the rotor between said end portions; c. an annular series of jet orifices extending through said annular portion and spaced thereabout and each oriented substantially normal to a radius of the rotor intersecting the orifice; d. a chamber housing having one end fixed to said second end portion and communicating smoothly into said rotor thereat, and having its other end supported by journals at said one journal support and communicating with said air intake housing to receive compressed air; e. a fuel injector connected with said regulator and extending through said intake housing and axially through said other end of the chamber housing and having a nozzle facing into the housing operative to spray fuel thereinto; f. a combustion chamber sleeve in said chamber housing mounted concentrically therein in spaced relationship to the chamber housing and supported to rotate therewith, the combustion chamber sleeve being longer than its diameter and terminating at one end which is necked down to closely fit around the nozzle while leaving an airspace therebetween, and the other end of the sleeve being Venturi shaped and extending beyond said second end portion and flairing into the rotor; the intake air being divided so that a smaller portion of it passes into the sleeve through said airspace and a larger portion of it passes into the rotor by passing between the sleeve and the chamber housing; and g. a solid particle fuel in slurry form, and means to ignite the fuel sprayed from the nozzle.

Claim 3

Dependent Claim 85 words

In a turbine set forth in claim 1, said peripheral portion of the rotor comprising a ring having a cross-section including a radially disposed step portion at each orifice, the radially disposed portions each having a hole therethrough disposed substantially normal to a radius of the ring at the stepped location, and an orifice tube in each hole, and the end portions of the rotor converging toward said ring so as to reduce the axial length of the rotor from its axis toward said ring.

Claim 4

Dependent Claim 59 words

In a turbine as set forth in claim 1, an exhaust collecting housing around said rotor; a heat exchanger having a path for receiving exhaust from said exhaust housing and having another path connected between said air compressor means and said air intake housing, for heating the air under pressure as it is delivered to the combustion chamber housing.

Claim 5

Dependent Claim 53 words

In a turbine as set forth in claim 1, said Venturi-shaped combustion chamber sleeve having spaced holes therethrough for admitting air thereinto from said chamber housing and for allowing solid particles and ash to be slung outwardly therefrom and entrained into the stream of air passing from the chamber housing into the rotor.

Claim 6

Dependent Claim 132 words

In a turbine as set forth in claim 1, said fuel injector comprising an elongated casing extending through the air intake housing and into said combustion chamber sleeve, the casing having a hollow rod extending therethrough and the fuel regulator being connected to the outer end of the rod, the fuel nozzle being located at the inner end of the rod to receive fuel entering therethrough, the nozzle being supported by the casing, a valve member at the inner end of the rod seatable against said nozzle to restrict it, and adjustable spring means operative to yieldably urge the rod toward the nozzle tending to close it against the opposing pressure of the fuel which tends to open it thereby to restrict the flow of fuel from said bore through the nozzle.

Claim 7

Dependent Claim 84 words

In a turbine as set forth in claim 5, said injector having a head portion at its inner end extending into said combustion chamber sleeve and including said nozzle, and electric fuel ignitors carried by said head and spaced about said nozzle in the path of the sprayed fuel, the air axially entering the sleeve through said airspace between the nozzle and the sleeve under pressure and the nozzle being operative to spray the fuel directly into the path of the axially entering air.
