3 Claims. 1
The present invention relates to power systems and particularly those in which a gas turbine operates in conjunction with a reciprocating engine.
It has already been proposed to operate a reciprocating engine from part of the gases produced in a gas turbine cycle. The invention contemplates operating such a reciprocating engine at a relatively high rate of efficiency while at the same time reducing the mass of rotatin machinery ordinarily required in conventional gas turbine cycles. This is accomplished by employing the air compressed in a gas turbine cycle as primary air for the combustion of fuel in a submerged combustion boiler irom which the steam and gas mixture is supplied to a reciprocating engine. The invention will be best understood upon consideration of the following detailed description of illustrative embodiments thereof when read in conjunction with the accompanying drawing in which:
Figure 1 is a diagrammatic view of a gas turbine plant combined with a submerged combustion boiler to operate a reciprocating engine in accordance with the present invention.
Figure 2 is a view similar to Figure 1 of a system utilizing a single stage of air compression instead of two stages as is shown in Figure 1.
In Figure 1, the gas turbine ll] drives the air compressors designated II and i2 in which air is compressed in two stages. A part of the air from the first stage compressor H is taken at say 380 F. and 65 p. s. i. by way of the branch duct l3 through the heat exchanger l4 to a combustion chamber IS in which fuel is burned with the air to provide gases at say 1200 F. and 65 p. s. i. for operating the turbine Ill. The remainder of the air compressed by the first stage compressor ll passes through the branch duct IE to the second stage compressor l2 and from the latter at higher pressure of 255 p. s. i. and 400 F. through the duct H; the greater part of the compressed air is conveyed through duct Hi to serve as primary air for the combustion of fuel in the submerged combustion boiler 20 which may be of any desired form. From the boiler 20 the mixture of steam and gases at say 345 F. and 255,
p. s. i. passes through the'separately fired superheater 2| to which the remainder of the second stage compressed air at 255 p. s. i. from the compressor i2 is carried through the branch duct I9. From the superheater 2| the steam and gas mixture at a temperature at around 700 and a pressure of about 250 lbs. is carried through conduit 22 to the reciprocating engine 23 in which the 2 steam and gas mixture expands useful work in the system.
In the form shown in Figure 2 a single air-com:-
to p rform the pressor ii is employed; part of the air from the" latter being supplied through the conduit as primary air in a second separately fired super-' heater 3| which receives part of the steam and gas mixture through duct 32 from the superheater 2| and heats it to a stillhigher tempera ture in the neighborhood of 1200 for operating the turbine i0.
In both of the systems described above the thermal efficiency may not be-quite as high as in a conventional gas turbine plant utilizing a regenerator but on the other hand they possess the advantage of permitting -a reduction in the amount of rotating machinery required because the amount of air to be handled in these systems is less than in conventional gas turbine cycles. This is because the submerged combustion boiler and separately fired superheaters require only a relatively small amount of compressed air for use as primary air in burning the fuel while at the same time volume of the gas and steam mixture from the boiler 20 and the high temperatures attained by superheating it permit a greater amount of useful power to be obtained by expansion of the gas and steam mixture in the expansion or reciprocating engine 23, the mixture to the engine being made up of approximately twothirds air and one-third steam which indicates the substantial reduction in the amount of air required. All of the compressed air is used for burning fuel in the submerged combustion boiler and in the superheaters. The quantity of air furnished need be only about 20% over the theo-- retical quantity for combustion while in a conventional gas turbine plant the air used is seven or eight times the combustion requirements in order that the gas temperature entering the turbine will not be too high. The reduction in the amount of reciprocating machinery required renders the systems described above practically suitable for use on locomotives or small boats where the space for the power installations is severely limited. Another important advantage of the systems described is that the submerged combustion boilers furnish heat storage in any desired quantity which is a. useful quality in the operation of either locomotives or small high speed boats.
The temperatures and pressures indicated in the drawings are approximate and merely illustrative since such factors as pressure drops in the piping, have not been taken into consideration in each instance.
