The typical combined heat and power plants requires the introduction of additional heating medium. The alternative solution is the direct integration of the exhaust gases from heat engine. The high temperature, surplus oxygen and low water content of the GTs exhaust gases enabled the successful integration at industrial scale as: preheated combustion air for industrial furnaces, heat source for drying and for absorption chillers. The article comprises the reference list for direct exhaust gas integration of GTs produced by GE, the processes overview, GTs selection criteria, as well as the review of documented GTs applications in process industry focusing on technical and economic considerations. The described solutions allowed to reduce the specific energy consumption in the range from 7 to 20% or the costs of energy consumption by 15-30%. The overall efficiency of cogeneration plant above 90% was achieved. The preliminary assessment of potential applications for GTs produced by GE with TEG integration in Polish process industry is done.
W artykule opisano możliwość zastosowania spalinowych silników turbinowych do napędu pojazdów szynowych. Scharakteryzowano zalety takich silników w stosunku do silników tłokowych, takie jak: korzystny wskaźnik mocy, większa trwałość, zasilanie gorszymi gatunkami paliw płynnych. Stwierdzono, że główną wadą tych silników jest mniejsza sprawność cieplna. Opisano układy napędowe wybranych, prototypowych pociągów z turbinowymi silnikami lotniczymi. Stwierdzono, że ten rodzaj napędu zwiększa zużycie paliwa w stosunku do silników turbinowych przeznaczonych do trakcji kolejowej.

The paper describes possibilities to apply internal combustion turbine s for the propulsion of railway vehicles. Advantages of a turbine over internal combustion piston engine were named: Favourable power to weight coefficient, higher durability, tolerance to the fuel of poor quality. However, lower thermal efficiency is the main disadvantage of these engines. Drive systems of selected prototype trains driven by the aircraft turbine engines have been described. It was found that such driving systems feature higher fuel consumption as compared with the turbine engines specifically designed for the use in rail vehicles.
