Which method should be used to warm up the pump turbines prior to discharge ________.
A.Lock the turbine rotor and slowly bleed in steam until operating temperature is reached
B.Run the pump at high speed with the discharge valves closed
C.Run the turbine at slow speed with the pump disconnected
D.Shut the discharge valve and run the pump at slow speed
第2题:

第6题:
cargo pump failure
blower failure
deck seal low water level
low inert gas temperature
第7题:
bypass exhaust gas at high loads to prevent excessive back pressure
bypass a portion of the exhaust gas at peak loads for better efficiency
recycle exhaust gas to the turbocharger
minimize moisture condensation in the boiler gas passages at low loads
第8题:
changing the direction of exhaust gas flow
increasing the exhaust gas velocity
changing the exhaust gas weight
increasing the exhaust gas static pressure
第9题:
intercooler
compressor
cylinder
open air
第10题:
Exhaust energy would draw excess air
The inertia of the turbocharger rotor causes a time lag which delays the turbocharger speed increase
Exhaust gas pumping losses are increased due to turbine windage
Exhaust gas back pressure falls slightly due to increased nozzle action
