🔍 Key Concepts

• Trace the flow path from the main condenser hotwell to and from the main condensate pump on Illustration SG-0010. • Locate the component actually labeled Hotwell Level Control Valve and see where its inlet and outlet are connected. • Consider why you would NOT normally control level by throttling pump suction on a condensate pump (think cavitation and loss of NPSH).

💭 Think About

• Starting at the main condenser hotwell symbol, follow the suction line into the main condensate pump, then follow all discharge branches. Which branch contains the hotwell level control device? • Look at what each discharge branch feeds: one goes to the main system, one may go to an air ejector, and another might return somewhere. Which arrangement would allow continuous control of water level in the hotwell? • If the condensate pump usually runs at constant speed, how can the system still regulate the hotwell level without changing pump speed?

✅ Before You Answer

• Verify exactly where the Hotwell Level Control Valve connects on the piping diagram (is it on pump suction, pump discharge to air ejector, or on a separate recirculating line?). • Confirm whether the line with the level control valve leads back to the main condenser/hotwell or out to another piece of equipment. • Eliminate any option that would require throttling the suction of the condensate pump, and any option that does not match the line where the level control valve is drawn.

According to the illustrated diagram, what statement is true concerning the operation of the main condenser hotwell level control device? Illustration SG-0010

The main condenser hotwell level is controlled by controlling the speed of the main condensate pump.

The main condenser hotwell level is controlled by throttling the flow in a recirculating line teed off the main condensate pump discharge line and leading back the main condenser.

The main condenser hotwell level is controlled by throttling the main condensate pump discharge to the main air ejector.

The main condenser hotwell level is controlled by throttling the main condensate pump suction from the main condenser hotwell.
