What is installed upstream in the steam line of the governor to protect an SSTG turbine from debris?

• A. Steam trap
• B. Steam strainer
• C. Pressure regulator
• D. Flow meter

Answer: (B)

The steam strainer is the correct choice because its primary function is to filter out debris and contaminants from the steam before it reaches sensitive components like the SSTG (Steam/Steam Turbine Generator). By installing a steam strainer upstream in the steam line, it ensures that only clean steam passes through to the turbine, thus preventing potential damage or malfunction caused by particles that could lead to wear or clogging. The steam trap, while important for removing condensate and air from the system, does not provide the necessary filtration for debris removal. A pressure regulator is responsible for maintaining a constant pressure in the steam system, but it does not address the issue of debris filtering. The flow meter measures the flow rate of steam but is not designed to filter or protect the turbine from harmful particles. Therefore, the steam strainer is essential for protecting the SSTG turbine and ensuring its efficient operation.
