Which method should be used to warm up the pump turbines prior to discharge?
AI Explanation
The correct answer is C) Shut the discharge valve and run the pump at slow speed.
This is the correct method to warm up the pump turbines prior to discharge. By shutting the discharge valve and running the pump at a slow speed, the turbine can be gradually warmed up to the proper operating temperature without putting excessive load on the system. This helps prevent thermal shock or damage to the turbine components.
The other options are not recommended. Running the turbine disconnected from the pump (A) would not properly warm up the system. Running the pump at high speed with the discharge valves closed (B) could potentially damage the pump. Locking the turbine rotor and slowly bleeding in steam (D) is a different procedure more suitable for boiler systems.
