Q

In the condensate system, the automatic recirculating valve can be actuated by the __________.

🔍 Key Concepts

• purpose of an automatic recirculating valve in a condensate system (protecting the pump at low flow conditions) • relationship between pump flow rate and the parameter used to open a recirculation path • how condensate system control signals are typically sensed (pressure, level, temperature, or flow)

💭 Think About

• Ask yourself: which of these four signals changes directly and reliably when the condensate pump’s flow to the system is too low? • Which signal would best protect the condensate pump from damage like overheating or cavitation if discharge flow is restricted or blocked? • Is the control of this valve more likely based on a local pump condition (like discharge pressure) or a remote system condition (like DC heater level or superheater steam flow)?

✅ Before You Answer

• Identify which choice directly reflects condensate pump operating conditions at its outlet rather than conditions elsewhere in the plant. • Eliminate any options that mainly indicate conditions in downstream equipment (heaters, superheaters) rather than the pump itself. • Check which parameter would give the fastest and most reliable indication of low flow through the condensate pump so the valve can recirculate flow in time.
