Question 638Steam Plants - Assistant Engineer
70% to passThe constant pressure governor of a turbine-driven feed pump maintains which of the following pressures at a constant value for all capacities?
APump discharge
BPump suction
CTurbine inlet
DTurbine exhaust
AI Explanation
The correct answer is A) Pump discharge. The constant pressure governor of a turbine-driven feed pump maintains the pump discharge pressure at a constant value for all capacities. This ensures that the feed pump provides a stable and consistent output pressure to the boiler, regardless of the system's demand or the pump's operating conditions. The other options are incorrect because the constant pressure governor does not maintain the pump suction pressure (B), the turbine inlet pressure (C), or the turbine exhaust pressure (D) at a constant value. These pressures may fluctuate based on the system's operational requirements and the pump's performance characteristics.
