Dear Sir,

 

I have Gas Turbine Performance curves in the form of Output Shaft speed, rpm ( x axis), % reference vs shaft power, % Reference( y axis) at various heat rates, % reference at various ambient temps. Separate map for each ambient temp...PFA GT Performance curve at particular temp of ambinet and it is also available for other temps,

 

I want to show the effect of ambient temp change on gas turbine performance in simulation.How to do it ?  How to calculate turbine efficiency from heat rate? Also tell me Shall i give speed from this curve to speed controller of turbine?

 

Can u please guide me ? 

 

Regards,

Chetan

You need to obtain a power correction vs. ambient temperature (inlet air temperature) curve from the turbine manufacturer.

Turbine Efficiency (%) = 3412 (Btu/kW) / Heat Rate (Btu/kW)*100%
