This work describes the effect of environmental polluted air properties (such as; temperature, relative humidity. volume fraction ratios of carbondioxide and carbon-monoxide ratio, and dust/sand particles) on the gas turbine performance. The polluted air properties are considered variable as under:
i) Air temperature varying from 270 .to 330°K. ii) Air relative humidity changing from 0 to 100%,and
iii) Reduction ratio in atmospheric pressure, due to the use of
air filter at compressor intake, varying from 60 to 100%.
The advanced BASIC Computer Programmes have been written for calculating the specific work and thermal efficiency of a gas turbine unit which works under the above conditions. The gas turbine performance values have been estimated by using various values of the maximum gas turbine inlet temperature (TIT) and pressure ratios (PR) (from 1200 to 1600° K, and from 10 to 16 respectively).
Specific heats of the mixture have also been considered as a function of temperatures and fuel air ratios.
The effect of environmental polluted air containing various ratios of Co, and CO2, on the gas turbine performance has also been investigated.
