Frame9 (HAS)
Hot Ambient Solution for Frame9 Gas Turbine
What it offers
Frame 9 (HAS) or Hot Ambient Solution is an upgrade of Frame 9 aiming to improve performance at high ambient temperature. It will increase the power up to 6 MW and thermodynamic cycle efficiency up to 1.3% (relative) or 0.4% (absolute) at target ambient temperature of 45°C. The main target here is to have the minimum cost. So, the major upgrade is based on compressor improvement. New IGV tuning and Stator blades re-staggering are the solutions to increase the compressor mass flow rate and maintain the compressor efficiency respectively.
The other modification is control logics (control system) re-adjustment. The most important advantage of HAS upgrade is producing the required power at high ambient temperature with no life reduction.
The upgrade has been designed to be performed during major inspection plan of Frame 9 with the same downtime as before.
Make the most out of the engine!
Air Compressor
- New IGV control logic
- New stagger angle for the compressor stators
A glimpse into the new design
These modifications need low, yet highly reasonable expenditure to be made to the gas turbine during the major overhaul. The main concept of Frame 9 (HAS) is to increase the compressor mass flow rate while maintaining its efficiency to produce more output power at 45⁰C ambient temperature. It is accomplished by compressor stators re-staggering, IGV opening and control logic improvement. The product has been designed to maintain the Frame 9 reliability, availability and maintenance plan. The same emission is expected and surge margin is generally kept the same as original version of Frame.
This upgrade offers higher cycle efficiency and output power at high ambient temperatures. It is also recommended for the sites which cannot produce the minimum required power at high ambient temperature. A comparison of the HAS version to the original design is shown in the figure.
