How Gas Turbine Inlet Guide Vanes Works. IGV, VGV

This video describes function of IGV of a Gas Turbine. This is one part of the IGV knowledge and rest will be covered in upcoming video.
Inlet Guide Vanes (IGVs) deliver air to the inlet of a gas turbine’s axial compressor. While maintaining proper fuel-to-air ratio through various load ranges, they minimize the potential for unwanted emissions. In present-day Combined Cycle power plants, IGVs ultimately control the exhaust gas temperature - a critical input to the Heat Recovery Steam Generator (HRSG). Stable control of the exhaust gas temperature enhances the combined unit’s level of efficiency.
Many current day turbines use low NOx combustors that require a lean air-fuel mixture. As hot gas temperatures decrease, the formation of NOx also decreases. With a higher air mix, it’s critical to control the exact amount of air into the combustors - especially during low loads.

Hello Sir, thank you for these great videos. Highly appreciated - thanks.

[@powerplantguru007]

Glad you like them!

[@vikassharma2704]

Very good video,
Please make video on IGV auto on and auto off and what parameters IGV uses to calculate its opening when working on auto mode

[@powerplantguru007]

Thank you for watching my videos. Igv on/off video is already created. Please go to my channel playlist and watch that

[@akashimitsumoto1464]

I newly started working at a thermal power plant specialized in gas turbines. Your video is brief yet so informative for beginners like me to understand. Thank you so much.

[@powerplantguru007]

Hello Akashi san
Thank you for watching my videos.
Really appreciate your kind words

[@jeremiahcalebhenry9054]

Thank you for the explanation. I'm currently working with MHI J series Turbine, and this was very helpful, also do a video on VGV. Both IGV and VGV combined video and how it works etc etc

[@ranadeera3561]

Excellent brother. Please keep doing more👍

[@nahid862]

Thanks for the amazing videos

[@powerplantguru007]

Thank you for watching my videos

[@larageneable]

Excellent explanation. Pictures very helpful to understand. Expecting more videos

[@powerplantguru007]

Thank you!
Sure, we will come up with more.

[@coolminded850]

Very clear and precise explanation. Plz keep it up.

[@powerplantguru007]

Thank you ❤️

Thank you

[@muhammadalhussain9245]

If the IGV open 84 with only 25mw and normal weather ,
Is this related to the quality of the inlet air? Also, the pressure differential of inlet air is high.
Thanks

[@powerplantguru007]

Hi Muhammad
You can check the air filter for choking.
The compressor may be fouled, you can check compressor efficiency by calculation and go for an offline water wash.

[@syed_taha_ahmed]

Can you please elaborate what is temperature slider in gas turbine control.

[@user-up2ob3uc5m]

hi .
we have a SGT100 typhone gas turbine.
can you explain how we can calibrate the VGVs?
thank you

[@powerplantguru007]

Hello thanks for reaching out, I have not worked on SGT100 and am not an expert on calibration. We have an expert panel where we have an instrument & control engineer.
You can join our Sunday session and ask that question.

[@eloymontes4334]

Friend, do you have a video where you talk about bearing from gas turbine

[@powerplantguru007]

Hello, thank you for watching my videos.
I have not worked on any video on bearings as of now.

[@TarangFF]

Hello sir
Can you pls make a detail video on HRSG

[@powerplantguru007]

Sure. What you want to understand in HRSG. It's very big topic.

[@powerplantguru007]

We can keep it clarifying your doubts

[@TarangFF]

Actually currently I'm doing my BE internship at GSECL, CCPP
I want to understand more about how actually it works, i have book information so i wanna know in plant how it works.... Simple overview

[@powerplantguru007]

Understand that

[@joshiiimt]

can u share any link for wheelspace temps

[@powerplantguru007]

Hello, Thank you for watching my videos.
I couldn't get you there, what link are you looking for?

[@viorep]

@powerplantguru007 I take it, the IGV do not guide anything, they only regulate the turbine inlet air flow. A very similar system is used to adjust the air flow through (exhaust) fans.
Anyway, many thanks for a good and useful video that you published here!

[@powerplantguru007]

Thanks

[@rafimarsidek3568]

very good content. subsribed. do you have group or channel that i can join?
