What is the main turbine gland sealing steam system designed to do?

🔍 Key Concepts

• Gland sealing steam purpose at turbine shaft penetrations • Effect of air leakage into a condenser on vacuum and turbine efficiency • Why a slight, controlled steam leakage at the glands can actually be desirable

💭 Think About

• Which choice best describes the overall function of the sealing steam system, not just one small detail? • Think about what would happen at the turbine end seals when the unit is at low load or turning gear speed—what must the system automatically take care of? • Would a properly designed gland system aim for zero leakage, or a very small, controlled amount in a particular direction?

✅ Before You Answer

• Identify which options describe preventing air from entering the turbine/condenser space. • Check which option mentions controlling or regulating pressure at different operating speeds and loads. • Decide whether the system is intended to have no leakage at all, or a small outward steam leakage to keep air from getting in.

Question 1 of 27070

What is the main turbine gland sealing steam system designed to do?

seal the turbine shaft against air leakage into the turbine casing

regulate steam pressure to the glands when the main turbine is operating at reduced speeds

allow minimal steam leakage out of the gland

all of the above
