steam turbine blade made of a martensite steel having high strength and high toughness, and a low pressure steam turbine and a steam turbine power generating plant using the steam turbine blades. Steam turbine blade made of a martensite steel containing C of 0.13 - 0.40 %; Si less than 0.5 %; Mn less than 1.5 %; Ni of 2 - 3.5 %; Cr of 8 - 13 %; Mo of 1.5 - 4%; at least one kind of Nb and Ta of 0.02 - 0.3 % in total; V of 0.05 - 0.35 %; and N of 0.04 - 0.15 %.
In HP Turbine total 17th stage 50% reaction type blading. From 1st. to 8th. stages are provided with ‘3DS’ blades, 9th. to 13th. stages with ‘TX’ blades and 14th. to 17 th. stages with ‘F’ blades.
Good 👍👍👍
Thanks
बहुत अच्छा गुरू जी प्रणाम 🙏🙏
Thanks
Sir, thank u very much for showing and explaining all the components.
Thanks
Great Effort sir
Welcome
Sir Automatic turbine run-up system video
Ok
I will try to make vedio on each and every important topic .
Unable to understand some parts.
Better u must hv used arrow pointer in video sir... While explaining.
Ok
Sir pls make a video on generator cooling and exiter also. Thankyou
Ok
ATT testing video pls
Ok
Inke photos Google drive pe dijiye please
