Abstract
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.

Claim 1
Independent Claim
248 words
In combination with a gas turbine having a compressor, a combustion chamber, a gas converter and a decompression turbine for complete and uniform combustion of the liquid fuel supplied thereto, the improvement which comprises: a. a first heat exchange means positioned in the path of the exhaust gases emanating from said decompression turbine, said first heat exchange means adapted to receive the air exiting from said compressor, said compressed air being heated by the exhaust gases passing through said first heat exchange means; b. means for supplying said heated compressed air to said combustion chamber; c. a second heat exchange means positioned in the path of the exhaust gases emanating from said decompression turbine, said second heat exchange means adapted to receive said liquid fuel, said liquid fuel being vaporized by the heat of the exhaust gases passing through said second heat exchange means; d. means for connecting said second heat exchange means to said gas converter for supplying said vaporized liquid fuel to said gas converter; and e. a gas converter comprising: 1. a plurality of reaction chambers; 2. heat exchange means in working relationship with each of said reaction chambers; 3. heat exchange means interposed between said reaction chambers; and 4. means for conducting a portion of the exhaust gases from said combustion chamber to each of said heat exchange mechanisms in said gas converter, whereby the heat of said exhaust gases given off in the gas converter heat exchange means facilitates the gas conversion process.
