True or False: Blade washing is conducted at speeds no more than 25% of full speed.

Blade washing is an essential maintenance procedure for turbines, aimed at removing accumulated debris and ensuring optimal performance. The correct answer reflects a general practice in the industry regarding the speed at which blade washing should take place. Operating at speeds no more than 25% of full speed ensures that the turbine blades can be cleaned effectively while minimizing the risk of damage to the blades or turbine components. At higher speeds, the forces exerted on the blades can be detrimental during the washing process, hence the precaution of limiting the speed.

In some scenarios, various turbines may have specific recommendations based on their design, but as a standard safety measure across many systems, the 25% limit is a widely accepted guideline for blade washing procedures. This practice helps maintain system integrity and prolongs the lifespan of the turbine components.
