Abstract
Disclosed herein is an improvement for a gas turbine which has been adapted to burn fuel processed by catalytic or non catalytic type gas converters. This adaptation has resulted in the reduction of the harmful polutants being emitted to the environment. The improvement, recognizing that a turbine operating with such processed fuel runs at considerably high combustion chamber temperatures, calls for the positioning of heat exchange mechanisms in the path of the exhaust gases emanating from the turbine''s decompression unit. These mechanisms preheat the fuel and air needed in the conversion process. Additionally, heat exchange mechanisms are positioned about and between the reaction chambers in the gas converter. Part of the exhaust gases are routed through these facilitating the gas conversion process. Further, mixing means are provided wherein the preheated air cooperates with the exhaust gases to reduce the heat of the latter before they pass via the turbine''s decompression unit into the environment. An alternate improvement calls for the placement of a water vaporizer in the path of the exhaust gases. Water supplied thereto is vaporized and then supplied to the gas converter for reaction with the fuel in a known way.

uniform combustion of the liquid fuel supplied thereto.
The health of the world's population is being endan-- combustion chamber and discharging from the decompression turbine is higher also.

gered more and more by iacreasing'airpollution. This is a particularly serious probleminthe thickly settled} areas. Exhaust gases not only from motor vehicles with internal-combustion engines. but also those emanating from stationary gas turbines contribute to this pollution problem. This is so primarily, because of, the nonuniform evaporation and inadequate intermixing'of the hydrocarbons and the combustion air.. resulting in inr complete combustion. The consequencer'of this is an burned or at best only partially burned hydrocarbons,
lt is'another object of this invention to provide an improved gas turbine which is supplied fuel gases from the gas convertertherebyachieving complete and uniform combustion.
it is still another object of this invention to provide a gas turbine which is more eiliclent than prior art turbines in that exhaust gas heat is recycled through the system prior todischarge into the environment to precarbon monoxide. condensation 'products,'j benzpy-;
renes, tarysoot and'aldehydesiz'lfhese are given off to it; ,1 ,20 The harmful secondary effects caused bythese exthe air via the exhaust gass haust gases can be reduced quite cons iderablyby the g use of a gas converter.

1 I SUMMARY oF'TIIE INVENTION in satisfaction of these objects and of others more readily apparent with a reading of the hereinafter disclosed invention, an improved gas turbine is provided which employs as its fuel the'reformed gas product of a gasconverter. The-compressed air required for combustionis preheated in a suitably arranged heat exthese gas converters. the fuel containing liquid hydro-fl f carbons is first evaporated, .vaporizedor atomizedQand the gaseous or vaporousfuel thus obtained isconducted over a catalyst for conversion into agas mixchange by the exhaust gases. The liquid fuel which is processed and converted to the reformed gas by the gas converter is also preheated and vaporized by the heat fof the "exhaust gases in a'suitable exchanger. Finally,

The conversion of the fuel into the fireformed gas can be made relatively soot free by feeding back a portion of the exhaust gas from the combustion. chamber of the enginefed with the reformed gas and mixing this exhaust gas with an oxygen-carrying gas such as air and passing this mixture together with the fuel through the converter. u
The gas converter employs perforated, sintered Dueto the combination of exhaust gas heat utilizathe conversion of the vaporized liquid fuel into the reformedgas by the gas converter. is facilitated by the lprovision of heat exchangers surrounding'and interposed between the reaction chambers of the converter.

They may be ofa non-catalytic type as described in the German Offenlegungsschriftj2,l32,8l9 or they can be of the catalytic type such as described in greater detail in the German Offenlegungsschrift 1,939,535. Where the catalytic type sintered blocks are employed, catalytic conversion of the hydrocarbons is obtained.v
As noted above, stationary gas turbines are also large polluters of the environment. it has been".recognized that asuitable way of materially reducing theemission of harmful pollutants by the gas turbines is an arrangement employing the gas converterdescribed in the preceding patent applications, in suitable fashion wherein the reformed gas generated bythe'converter becomes the fuel for'the' gas turbines. V
A gas turbine usually consists of a compressor forthe air required for combustion, a combustion chamber and a decompression turbine. The amount of air required for the combustion process in the gas turbine, including the excess air required for maintaining the maximum combustion temperature. is provided by the compressor.
A gas turbine operated with such reformed gases and compressed air can be run at considerably high combustion chamber temperatures than the conventional gas turbines. Therefore, the temperature of the exhaust gases entering the decompression turbine from the overallefficiency of more than 40 percent can be achieved. Mixing means are also provided for'eooling I the exhaust gases resulting in a temperature compatible with the decompression turbine design. Further, in yet another embodiment of this invention, a steam generator is placed in' the path of the exhaust'gases exiting from the decompression turbine; Water is converted to water vapor. which is in turn supplied to-:the gas converterwhere it reacts with the preheated fuel instead of the exhaustfgases to achieve conversionof the vaporized fuel to these-called reformed gas.
BRIEF DESCRlPTlON OF THE DRAWINGS FIG. 1'. is a schematic representation of the subject invention DESCRIPTION OF THE PREFERRED I EMBODIMENT combustion and routes that compressed air to the remainder of the system through line 8. The compressor and decompression turbine 4 are shown connectedtogether by line 31, which represents the common shaft upon which both would rotate in a standard turbine de-,
This facilitates the conversion of the vaporized fuel inline 9 to the reformed gas supplied to the combustion chamber. The exhaust gases exit'from heat exchangers 14, l7, 15, 18 and 16 via ducts 34'.,35', 36', 37' and 38 .respectively. These are combined through a suitable manifold arrangement and supplied by way of line 23 to mixing chamber 7. 4
Mixing chamber 7, as noted earlier, is also supplied by the compressed air exiting from heat exchanger 6. Although preheated, this air is less than the temperature of the exhaust gases in line 23. Within mixing chamber 7, the compressed air exiting from heat exchanger 6 extracts some of the heat from the exhaust gases in line 23. The exhaust gases, reduced in temperature, are supplied to the decompression turbine 4 via line 11.
The decompression turbine directs the exhaust gases, exiting therefrom by line 12 through the heat exchange devices 6 and 5. As they passthrough the exchangers, the exhaust gases preheat both the air andthe liquid fuel prior to their use in the remainder or balance ofthe system.
Once past the heat exchangers 6 and 5, the exhaust gas exits to the outside environment via duct or exhaust pipe 12'. I
In an alternate embodiment of the subject invention. a steam generator 24, shown in phantom may be inserted in the path of the exhaust gases emanating from the decompression turbine. Water is supplied thereto by line 39. The heat of the exhaust gases converts the water to steam, which is then routed to the gas converter 2 through line 25. in this arrangement the exhaust ga's fed to the converter 2 is completely or par- .tially replaced (through suitable valving, not shown) by the steam, which thereafter reacts with the fuel in a well-known conversion process.
