Which of the listed conditions aids in directing gland leakoff steam from the low-pressure propulsion turbine to pass through the gland exhaust condenser?
• Steam turbine gland sealing systems and how leakoff steam is normally removed • Purpose and function of a gland exhaust condenser • Role of mechanical vs. pressure-driven devices in moving low-pressure steam
• Ask yourself: In a low-pressure area like turbine glands, is there usually enough pressure in the leakoff steam itself to push it where it needs to go, or do we need some kind of assist? • Which option describes equipment that is specifically designed to move vapors/air/steam from one place to another? • Which answer choices describe pressures that might already be very low at the gland area, and which describe an active system that could create flow?
• Identify which choice is a mechanical means of creating suction or flow, rather than just a source of steam pressure. • Consider the normal purpose of a gland exhaust condenser: it handles low‑pressure steam and air from the glands. How does that flow get there? • Eliminate any answer that relies solely on turbine internal steam pressure in areas that are already low pressure by design.
