Gas Turbine

Documentation of the input data as well as the output data of the gas turbine.

The gas turbine can either be modelled via the GT-Macro (component 40) or from individual components. When modeling with individual components, the combustion zone of the gas turbine as well as the generator must be specified.

The data of the gas turbine are defined as:

the data on the air line at the inlet of the compressor.
the data on the fuel line at the GT-inlet.
flue gas at the outlet of the turbine.
the mechanical power at the outlet of the turbine.
the electrical power produced by the generator.
the material composition on the last flue gas line (in volume %).

Depending upon the configuration the number of lines in the documentation of the data on the lines can change and hence also the appearance of the report.

The following configurations are implemented:

GT-Macro

Component	Name	Line	Fluid
40	GT-Macro	1	Ambient air inlet
		3	Fuel inlet
		4	Injection water/steam inlet
		2	flue gas outlet
		5	Electrical power
