Gas Turbine and Internal Combustion Engines,both are used to produce Power for operations of other Machines.Below are some points,which shows that the Gas Turbine is better in performance and use,than Internal Combustion Engine.
01)In winter nights,specially in cold regions,some provision has to be made to prevent Freezing in Internal Combustion Engines using Water Cooling when the Temperature of the Atmosphere falls to sub zero values.Anti-Freezer is generally used for this purpose.
There is no danger of Freezing,as Gas Turbine does not use any Water.On the other hand Gas Turbine works better if the Temperature of the Atmosphere falls below.
02)The Output from a Gas Turbine increases if the Inlet Temperature of the working Fluid decreases.At the High Altitudes where the Temperature of the Air is quite low,the Output of the Aviation Gas Turbine can be well maintained.
While the Output of Internal Combustion Engine at High Altitude would decreases.
03)For the same Output,the weight per Horse Power of a Gas Turbine is about one third that of Reciprocating Piston Type Internal Combustion Engine.That is why,the Turbojet Engines are being more commonly used in AirCrafts.
04)A Low Grade Fuel can be used in Gas Turbine.In some cases even Coal and Peat have been burnt.Low Grade Fuel can not be used in InternalCombustion Engines.
05)The Fuel and Lubrication cost in Gas Turbine is lower comparing to Internal Combustion Engine.
You can add few points,if you know something about the topic.
