Dear Forum Members
A very happy New year to you all.
I'm planning to calculate gas turbine driven compressor efficiency.
P1=7 bar , T1 = 30 Deg C
P2=22 Bar , T2 =130 Deg C
Below are my queries -
1) Which inlet suction flow to be considered for calculation purpose??
Flow before Anti-surge line(A) or flow after anti-surge line( B ) .
How to consider Anti-surge valve opening effect in efficiency calculation??
Will its effect only be on fuel gas consumption of Gas turbine??
2) Adiabatic index for natural gas(Mol Wt =17.2),I am taking 1.3.
3) Polytropic index calculation will be from the formula
P1/P2 = (T2/T1)^(n/n-1)
4) I 'm calculating Efficiency by below formula
= (Work done by compressor) / (Fuel gas consumption Energy)
Any addition/suggestion will be most welcome.
Regards
Aditya
