Question 1 of 27070

The quantity of heating steam supplied to the feed water heater of a two-stage flash type distilling plant is held relatively constant by a/an __________.

🔍 Key Concepts

• steam flow control methods in distilling plants • the normal function of an orifice plate vs a pressure regulator • how a two-stage flash distilling plant maintains steady heating conditions

💭 Think About

• Which device is typically used to keep a nearly constant flow when the upstream pressure may vary but you want steady flow through a heater? • Which of these choices is primarily designed to control temperature, which to control pressure, and which to create a fixed restriction? • In a two-stage flash type distilling plant, why is it important to keep the heating steam rate into the feedwater heater relatively constant, and which device best supports that goal automatically?

✅ Before You Answer

• Identify which option is specifically intended to maintain a set pressure or flow automatically, not just throttle manually • Recall that an orifice plate gives a fixed restriction but does not actively adjust to changing conditions • Make sure you are clear on the difference between an attemporator (temperature control) and a pressure/flow control device before choosing
